Chapter V: Part II (1)

[*]=Acacia Julibrissin.=--A native of Persia, with large and elegant much-divided leaves, and flowers somewhat like short tinted brushes from the numerous purple stamens. Though this does not succeed as a standard tree in all parts of England (where it grows well against walls, and sometimes flowers), yet doubtless it would do so in some parts of the south, and I have seen it make presentable standards about Geneva and in Anjou. But for our purposes it is better that it should not be perfectly hardy, as by confining it to a single young stem and using young plants, or plants that have been cut down every year, we shall get an erect stem covered with leaves more graceful than a fern, and that is the kind of ornament we want as a graceful object amidst low-growing flowers. The leaves, like those of some other plants of the pea tribe, are slightly sensitive. On fine sunny days they spread out fully and afford a pleasant shade; on dull ones the leaflets fall down. This interesting phenomenon takes place with other members of the same family--for instance, the elegant _A. dealbata_ of our conservatories. Seed of _A. Julibrissin_--or the silk-rose, as it is called by the Persians in consequence of its silky stamens--is readily obtained, and it is much better raised from seed, as then you get those single-stemmed and vigorous young plants which are to the flower-garden what an elegant fern is to the conservatory or show-house. To succeed with it in the way above named, it may be protected at the root and cut down every year in spring, or strong young plants may be put out annually, in much the same way as those of _A. lophantha_.

[*] _The names of all hardy species and other kinds easily raised from seed in spring (the kinds useful in all classes of garden), are preceded by an asterisk._

=Acacia lophantha.=--This elegant plant, though not hardy, is one of those which all may enjoy, from the freedom with which it grows in the open air in summer. It will prove more useful for the flower-garden than it has ever been for the houses, and, being easily raised, is entitled to a place here among the very best. The elegance of its leaves and its quick growth in the open air make it quite a boon to the flower-gardener who wishes to establish graceful verdure amongst the brighter ornaments of his parterre. It has graceful fern-like leaves and a close and erect habit, which permits us to closely associate it with flowering plants without in the least shading them or robbing them. Of course I speak of it in the young and single-stemmed condition, the way in which it should be used. By confining it to a single stem and using it in a young state, you get the fullest size and grace of which the leaves are capable. Allow it to become old and branched, and it may be useful, but by no means so much so as when young and without side branches. It may be raised from seed as easily as a common bedding plant. By sowing it early

Ornamental foliaged herbaceous Section; retaining its leaves till very late in the year.]

in the year it may be had fit for use by the first of June; but plants a year old or so, stiff, strong, and well hardened off for planting out at the end of May, are the best. It would be desirable to raise an annual stock, as it is almost as useful for room-decoration as for the garden. Native of New Holland.

ACANTHUS.

These stout and hardy herbaceous plants are of the greatest importance in the subtropical garden or the pleasure-ground, their effect being very good when they are well established. They thrive in almost any soil, but attain their greatest luxuriance and beauty in deep warm ones. The best uses for these species are as isolated tufts in the grass, in the mixed border, or in picturesque groups with other hardy subjects. In all cases they should be placed in positions where they are not likely to be disturbed, as their beauty is not seen until they are well established. All are easily propagated by division. Few herbaceous genera may be made more useful than this.

=*Acanthus hirsutus.=--This uncommon species has a narrow spiny leaf, more in the way of _Morina longifolia_ than the ordinary Acanthuses, and is dark green in hue. The leaves grow to a length of about 15 ins. or 16 ins. in ordinary soil. Being distinct, it may be worth growing, though in point of character or importance it is inferior to the larger kinds. South of Europe.

=*Acanthus latifolius.=--The leaves of this are bold and noble in outline, and the plant has a tendency, rare in some hardy things with otherwise fine qualities, to retain them till the end of the season without losing a particle of their freshness and polished verdure. In fact, the only thing we have to decide about this subject is, what is the best place for it? Now, it is one of those things that will not disgrace any position, and will prove equally at home in the centre of the mixed border, projected in the grass a little from the edge of a choice shrubbery, or in the flower-garden; nobody need fear its displaying anything like the seediness which such things as the Heracleums show at the end of summer. I should not like to advise its being planted in the centre of a flower-bed, or in any other position where it would be disturbed; but in case it were determined to plant permanent groups of fine-leaved hardy plants, then indeed it could be used with great success. Supposing we have an irregular kind of flower-garden or pleasure-ground to deal with (a common case), one of the best things to do with this Acanthus is to plant it in the grass, at some distance from the clumps, and perhaps near a few other things of like character. It is better than any kind of Acanthus hitherto commonly cultivated, though one or two of these are fine. Give it deep good soil, and do not grudge it this attention, because, unlike tender plants, it will not trouble you again for a long time. Nobody seems to know from whence it came. Probably it is a variety of _Acanthus mollis_. The plant varies a good deal; I have seen specimens of it about a foot high, with leaves comparatively small and stiff and rigid, as if cast in a mould, by the side of others of thrice that development, and of the usual texture.

=*Acanthus longifolius.=--A fine, distinct, and new species from Dalmatia and S. Europe, 3½ ft. to 4 ft. high, distinguished from _A. mollis_ (to which it is allied) by the length and narrowness of its arching leaves. They are about 2½ ft. long, very numerous, of a bright green colour, growing at first erect, then inclining and forming a sheaf-like tuft, which has a very fine effect. The flowers are of a wine-red colour, becoming lighter before they fall. A specimen in the gardens of the Museum at Paris, in four years after planting, had twenty-five blooming-stems rising from the midst of a round mass of verdure nearly 2½ ft. in height and width. This would be very effective on the undulating and picturesque parts of landscape-gardens. It does not run so much at the root as _A. mollis_. It seeds more freely than the other kinds, and may be readily increased by seeds as well as by division. Its free-flowering quality makes this species peculiarly valuable, while it is as good as any for isolation or grouping.

=*Acanthus mollis.=--A well-known old border-plant from the south of Europe, about 3 ft. high, with leaves nearly 2 ft. long by 1 ft. broad, heart-shaped in outline, and cut into angular toothed lobes. The flowers are white or lilac, the inflorescence forming a remarkable-looking spike, half the length of the stem. Well adapted for borders, isolation, margins of shrubberies, and semi-wild places, in deep ordinary soil, the richer the better. Increased by division of the roots in winter or early spring.

=*Acanthus spinosissimus.=--This is in all respects among the finest of thoroughly hardy “foliage-plants,” growing to a height of 3½ ft., and bearing rosy-flesh-coloured flowers in spikes of a foot or more in length. It is perfectly hardy, very free in growth, and is quite distinct from any of the other species, forming roundish masses of dark-green leaves, with rather a profusion of glistening spines, by which it is known immediately from its relatives. As a permanent object, fit to plant in a nook in the pleasure-ground or on the grass, associated with the nobler grasses or other plants, there is nothing to surpass it. I know of no hardy foliage-plant so thoroughly neat in its habit at all times. It does not often flower; and if it should throw up a spike, it will perhaps be no loss to cut it off, as its leaves are its best ornament, though the flowers too are interesting. Never at any time does it require the least attention; it will stand any exposure; and is, in a word, invaluable as a hardy ornamental plant. It will thrive best in good and deep soil. South of Europe.

=*Acanthus spinosus.=--This species appears to flower well more regularly than any other. Its leaves are rather narrow, and very deeply divided into almost triangular segments: they are also covered with short spines. The flowering-stems are about 3 ft. high, and bear dense spikes of purplish flowers. Useful for borders, or grouping with the other kinds and plants of similar character and size. South of Europe.

=*Adiantum pedatum.=--This fern, which abounds in the woods of Canada and the United States, is unquestionably one of the most elegant of those which are able to endure the climate of Britain, and grows from 16 ins. to 20 ins. high. From the tops of the erect black stems the fronds branch and spread horizontally in a very graceful and peculiar manner. The leaflets are slightly wedge-shaped, the upper margin resembling an arc of a circle. The American Maiden-hair flourishes in a light cool soil, and in a half-shaded position, or in a coarsely-broken, shallow, turfy peat soil, covered with a layer of moss to keep it constantly cool. It is commonly grown in the greenhouse with us, but is especially adapted for embellishing the low and shady parts of rockwork, and for ornamenting beds and mounds of peaty soil which have a north aspect or are sheltered from the full sun. It is propagated by division of the tufts in autumn or early spring. If done in autumn, the divisions should be potted and placed under a frame for the winter, as they form new roots more readily if so treated. There can be no question that, if planted in rich moist soil in a shady wood, we should have no trouble in naturalising this graceful fern, the fronds of which are such graceful objects in the dense woods of the “great country.”

=Agave americana.=--This and its variegated varieties are plants peculiarly suited for subtropical gardening, being useful for placing out of doors in summer in vases, tubs, or pots plunged in the ground, and also for the conservatory in winter. It forms a large rosette of thick fleshy leaves of a glaucous ashy-green colour, overlapping each other at the base, from 4 ft. to 6½ ft. long, and from 6 ins. to 10 ins. broad, ending in a strong spine, and having numerous spines along the margin. When the plant flowers, which it does only once, and after several years’ growth, it sends up a flowering-stem from 26 ft. to nearly 40 ft. high. The flowers are of a yellowish-green colour, and are very numerous on the ends of the chandelier-like branches. It will grow in any moderately dry greenhouse or conservatory in winter, or even in a large hall, and may be placed out of doors at the end of May and brought in in October. All the varieties are easily increased from suckers. N. America.

=*Agrostis nebulosa.=--This beautiful annual grass forms most delicate feathery tufts about 1 ft. or 15 ins. in height, terminated when in flower by graceful panicles of spikelets, which are at first of a reddish-green colour, and afterwards change to a light red in the upper part, the remaining two-thirds being of a deep green: the pedicels are extremely slender and of a violet colour. It forms very handsome edgings, and is very valuable for bouquets, vases, baskets, room and table decoration, etc. If cut shortly before the seed ripens, and dried in the shade, it will keep for a long time. Dyed in various colours it is much used by makers of artificial flowers. It may be sown either in September or in April or May. In the former case it will flower from May to July, in the latter from July to September. The seed, being very fine, should be only slightly covered. Though small, this deserves a place in groups of the finer and dwarfer plants, such as _Thalictrum minus_, and also in herbaceous borders. Spain.

=*Ailantus glandulosa.=--Much trouble and expense are incurred in the purchase, growth, and protection of tender plants with fine compound leaves like this, but which in our climate never display anything like the fresh vigour, health, spotless appearance, and youthful grace characteristic of hardy subjects. This is one of the most valuable of the hardy trees which, if kept in a dwarf state by being planted young and cut down annually, will furnish as good an effect as any tropical plant. The Ailantus should be kept in a young state, with a single stem clothed with its superb pinnate leaves; and we can readily keep it in this form by planting it young and cutting it down annually, taking care to prevent it from breaking into an irregular head, as then the symmetry of the leaf beauty becomes confused and is not at all so effective as when it is kept to a single stem. Vigorous young plants and suckers in good soil will produce handsome, arching, elegantly divided leaves 5 ft. and even 6 ft. long, not to be surpassed by those of any stove-plant. Under such treatment it could be grown conveniently to about from 4 ft. to 7 ft. high, and would thus do grandly for association with the larger class of garden flowers--Gladioli, Dahlias, and Hollyhocks, for example--while among Cannas and the like it will prove fine. The leaves are not liable to be attacked by insects--a good point in a plant used for the purpose I suggest--and they retain their healthy green till the first frosts in November, when they suddenly drop off. It is propagated with facility by cuttings of the roots, but is cheap in all nurseries. China and Japan.

=*Aira pulchella.=--One of the most ornamental grasses, with numerous hair-like stems, growing in light elegant tufts 6 ins. to 8 ins. high. It is useful for forming very handsome edgings, or for interspersing amongst plants in borders, or growing in vases or pots for room-decoration. Its delicate panicles give an additional charm to the finest bouquets. May be sown either in September or in April. S. Europe.

=*Alisma Plantago.=--A native perennial water-plant, growing nearly 3 ft. high, and bearing a very handsome pyramidal panicle of rosy-white flowers from June to September. The leaves are oval-lance-shaped with a cordate base, and are borne nearly erect on long stalks for some distance above the surface of the water. A graceful object on the margins of ponds, lakes, etc., where a plant of it transferred from any place where it grows will soon increase.

=Alsophila excelsa.=--A noble tree-fern, native of Norfolk Island, where it attains a height of 40 ft., crowned with a magnificent circular crest of bipinnate fronds. These fronds or branches fall off every year, leaving an indentation in the trunk. It stands well in the open air in this country in shady, moist, and thoroughly well sheltered places. It should be put out at the end of May, and taken indoors at the end of September or early in October, and receive warm-greenhouse or temperate-house treatment in winter. The same remarks apply to _A. australis_, and probably others of the family will be found to thrive well in the open air when sufficiently plentiful to be tried in that position.

*THE AMARANTUSES.

Among the common annuals of our gardens I know of none more in want of judicious use and appreciation than these. The few we grow are usually treated as rough common annuals, and sown so thickly that they never attain half their true development, or never fulfil any of the graceful uses for which they are adapted. But the family possesses greater claims on our attention by reason of the more recent additions to it. The old “Love lies bleeding” (_A. caudatus_), with its dark-red pendent racemes, is a very striking object when well grown, but _A. speciosus_ and some of the more recent varieties are still more so.

=*Amarantus caudatus.=--A hardy and vigorous-growing species, from 2 ft. to 3¼ ft. high. Flowers from July to September, dark purplish, very small, collected in numerous whorls, which are disposed in drooping spikes so as to form a handsome pendent panicle. There is a variety which has yellow flowers and is equally hardy. It is advisable to give this plant plenty of room to spread; otherwise much of its picturesque effect will be lost; and to use it in positions where its fine and peculiar habit may be seen to advantage,--as, for example, in large vases, edges of large beds of subtropical plants, or dotted among low-growing flowering plants. Although as easily raised as any common annual, it deserves to be properly thinned out, and each plant isolated in rich ground, so that it may attain its full size. E. Indies.

=*Amarantus sanguineus.=--Is distinguished by the blood-red colour of its leaves, and grows about 3 ft. high. Its purple flowers appear from July to October, disposed partly in small heads in the axils of the upper leaves, and partly in slender, flexible spikes which form a panicle more or less branching. This plant, though a native of the East Indies, is quite hardy, and seems to do best in light soil with plenty of leaf-mould and having a warm aspect. It may be sown in hotbeds in April and pricked out in May, or in the open air at the end of April or beginning of May, and, like the others, should never be allowed to get crowded.

=*Amarantus speciosus.=--A very large kind, well adapted for associating with subtropical plants, as it grows from 3 ft. to nearly 5 ft. high. The flowers are very numerous, of a dark crimson purple, and arranged in large erect spikes, forming a fine plumy panicle. The leaves are suffused with a reddish tinge. Plants of this species are occasionally met with having leaves with a light green centre surrounded by wavy zones of a reddish hue. This colouring disappears at the time of flowering. It is an effective subject in the autumn months. Culture, the same as for the preceding kind. Nepaul.

=*Amarantus tricolor.=--Distinguished by the very handsome and remarkable colouring of its leaves, which are of a fine transparent purplish-red, or dark carmine, from the base to the middle. A large spot of lively transparent yellow occupies the greater part of the upper end of the leaf, and sometimes covers it altogether, with the exception of the point, which is mostly green. The leaf-stalk is either of a light green or yellow colour. Sometimes leaves occur which have the lower half green and the upper part red. Another variety (_bicolor_) has leaves of a tender green variously streaked with light yellow. It is rather delicate, and requires very good soil, and a warm, open aspect. Another variety (_bicolor ruber_) is hardier than the last-named, and has leaves which are of a brilliant glistening scarlet when young, gradually changing to a dark violet-red mixed with green. Another variety (_ruber_) has a more squat and ramified habit, and leaves of a deep rose-colour thickly clothing the stems. Other varieties recommended are _elegantissimus_ (with scarlet leaves), _Gordoni_, _melancholicus ruber_, and _versicolor_, all having some claims as bedding plants. The foliage of these varieties is exceedingly ornamental, and rivals the finest flowers in the richness of its hues. Planted along with large-leaved subjects, such as the Cannas, Wigandias, Ricinus, Solanums, etc., the effect is very fine. They may also be advantageously employed in borders and flower-beds of all sizes, and for fringing the edges of shrubberies. The varieties of _A. tricolor_ are a little more tender than the other kinds, and a light soil and a warmer position are necessary for them. They do well in gardens by the seaside. They should be sown in April in a hotbed, pricked out in a hotbed, and finally planted permanently about the end of May. _A. t. giganteus_ is described as very fine in recent catalogues of the nurserymen. To these may be added a beautiful new kind, _A. salicifolius_, in the possession of the Messrs. Veitch, but not yet sent out. It has highly coloured and very long, narrow, and arching leaves, and is a singularly graceful and brilliant object. E. Indies.

=*Andropogon squarrosus= is a hardy East Indian grass, which survives the winter with but slight protection, making luxuriant tufts seven feet high, or more, when in flower. It would probably make a beautiful object in the warmer and milder parts of England and Ireland in good soil, but it is not a subject which can with confidence be recommended for every garden. However, all who value fine grasses should try it. Well-drained and deep-sandy loam.

*ARALIAS.

This genus embraces many plants of very diverse aspects, and few that are fitted for the open air in our climate; but in the case of _A. canescens_, and its relative (_A. spinosa_), the Angelica-tree of North America, we have subjects which thrive perfectly well in our gardens, and which in the size and beauty of their leaves are far before many “foliage-plants” carefully cultivated in hothouses at a perpetual expense.

=*Aralia canescens.=--The specimen of this species figured was one of a batch of young plants growing in a London nursery, and sketched in the summer of 1868. The engraving falls far short of rendering the beauty of the plant. It is easy to imagine what a graceful effect may be realised by such an object, either isolated on the turf near the edge of a shrubbery, or grouped with subjects of similar character. Success with these plants may be secured by first selecting a sheltered and warm position, so that their noble leaves may be well developed and not lacerated by storms when they are fully grown; secondly, by giving them a deep, free, and thoroughly-drained soil; and thirdly, by confining them as a rule to a simple and rather dwarf stem, so that the vigour of the individual may not be wasted in several branches. The effect of a plant kept to a single stem, as shown in the plate, is always much superior to that of a branched one. Young plants present this aspect naturally; but old ones may be cut down,

Deciduous fine-leaved Shrub; hardy everywhere.]

when they will shoot vigorously. If the effect of a full-grown specimen be desired, the shrubbery is the place for it. = _A. japonica (Hort.)._

=*Aralia edulis.=--This is a vigorous herbaceous perennial, well suited for those positions in which we desire a luxuriant type of vegetation. It is perfectly hardy, is of a fresh and vigorous habit, and grows 6, 7, and even 8 ft. high in good soil, even so early as the end of June. The leaves attain a length of nearly a yard when the plant is strong, while the shoots droop a little with their weight, and thus it acquires a slightly weeping character. It is rare in this country now, but, being easily propagated, may, it is to be hoped, not long prove so. As it dies down rather early in autumn, it must not be put in important groups, but rather in a position where its disappearance may not be noticed. An isolated position, or one near the margin of an irregular shrubbery, fernery, or rough rockwork by the side of a wood walk, will best suit it. Japan. Division.

=*Aralia japonica.=--A valuable species, quite distinct from any of the others, with undivided, fleshy, dark-green leaves. It is usually treated as a green-house plant, but is hardy and makes a very ornamental and distinct-looking shrub on soils with a dry porous bottom. It grows remarkably well in the dwelling-house; in fact it is one of the very few plants of like character that will develop their leaves therein in winter. Not difficult to obtain, it may be used with advantage in the flower-garden or pleasure-ground among medium-sized plants--say those not more than a yard high. It would form striking isolated specimens on the turf, and is also very suitable for grouping. A native of Japan. = _A. Sieboldi._

=*Aralia nudicaulis.=--A very vigorous perennial, with a smooth stem scarcely rising out of the ground, bearing large leaves with long-stalked, oval-oblong, pointed, toothed leaflets, and a shorter naked flower-stem, with from two to seven umbels of blossoms. Roots several feet long and highly aromatic. Similar uses to those directed for _A. edulis_. North America.

=Aralia papyrifera= (_Chinese Rice-paper Plant_).--This, though a native of the hot island of Formosa, flourishes vigorously with us in the summer months, and is one of the most valuable plants in its way, being useful for the greenhouse in winter and the flower-garden in summer. It is handsome in leaf and free in growth, though to do well it must, like all the large-leaved things,

be protected from cutting breezes. If this Aralia be planted in a dwarf and young state, it is likely to give more satisfaction than if planted out when old and tall. The leaves spread widely out near the ground, and then it is very ornamental through the summer. Prefer therefore dwarf stocky plants when planting it in early summer. It should have rich, deep soil and plenty of water during the hot summer months. For the public gardens of Paris it is kept underground in caves during the winter; but in private gardens it will doubtless be thought worthy of a place in the greenhouse throughout that season. In Battersea Park a bed of _A. papyrifera_, 13 ft in diameter, attained a height of 5 ft, from cuttings struck in the spring of 1868. The plants were left out all the next winter, and, although killed to the ground, the thick fleshy roots next season produced numerous strong shoots or suckers. These were produced irregularly, and so numerously that they had to be thinned out in many places; a few spaces only requiring to be filled up. It is easily increased by cuttings of the root, and is usually planted in masses, edged with a dwarfer plant; but as a small group in the centre of a bed of flowers, or even as an isolated specimen in a like position, it is most excellent.

=*Aralia racemosa= (_American Spikenard_).--An herbaceous species, with smooth, widely-branching, diverging stems, about 4 ft. in height, and pinnate, slightly downy leaves with ovate heart-shaped leaflets. Flowers numerous, white, in racemose umbels. Thrives best in good soil in shady or half-shady positions. Similar positions, etc., to those for _A. nudicaulis_ and _edulis_. N. America.

=*Aralia spinosa= (_Angelica tree of North America_) is highly useful, in consequence of its beauty of foliage, among subtropical plants. Like many of the hardy things, it should not be placed in positions where it would be necessary to remove it, nor closely associated with tender plants requiring frequent disturbance of the soil Flowers in autumn, small, white, in numerous umbels arranged on a much-branched panicle beset with velvety stellate down. The leaves are twice and thrice pinnate, with ovate, deeply serrated, smooth leaflets. In most cases it grows with a single erect stem--the very type we require--and it should not be allowed to depart from this habit. The stem is fiercely arrayed with spines. On account of its umbrella-like head this fine thing has often been planted in exposed open spaces, where it would produce a distinct feature, but it is better planted where the great leaves will not be lacerated. It generally grows not more than 10 ft. high; and in every size from that down to a plant with a stem not more than 18 ins. high, it may be effectively used in the ornamental garden. It is propagated by cuttings of the roots. N. America.

=Aralia macrophylla= is a fine large digitate-leaved species which stands summer exposure pretty well, but does not make any growth in the open air; hence it can be but of comparatively slight importance for this purpose. Norfolk Island.

=Areca sapida.=--A New Zealand palm from 6½ ft. to nearly 10 ft. high, with a beautiful crown of bright-green pinnate leaves, which when young are tinged with a bronze colour: leaflets from 16 ins. to 2 ft. in length, lance-shaped. The young leafstalks are of a greyish red hue. A fine palm for placing in the open air in summer, and equally so for the conservatory in winter and spring. It is of very easy culture, if supplied with plenty of water.

=Aristolochia Sipho.=--This well-known huge-leaved plant is capable of being used with excellent effect where large and distinct foliage is desired. Generally it is used as a wall plant; but it is far finer when used to cover bowers or any like structure. I have seen a most effective object formed by making the framework of a tent loosely with rough boughs, and then planting the Aristolochia around it. It formed a dense green and singular-looking wigwam. _A. tomentosa_ is smaller, but distinct in tone of green, well worthy of a place, and to be employed in like manner. N. America.

=*Artemisia anethifolia.=--A hardy perennial species about 4 ft. high, with a simple round stem, woody at the base, and branching vertically above, clothed from about a foot above the ground with much-divided leaves, the segments of which are almost thread-like. Flowers very numerous, small, in a dense, large, terminal panicle, with erect branches. Useful in groups, or as isolated specimens in beds or borders. Division.

=*Artemisia annua= (_Annual Wormwood_).--An exceedingly graceful kind of wormwood, with tall stems reaching to a height of 5 ft. or 6 ft. in a season; the foliage is small and fine, and the flowers inconspicuous but arranged in not inelegant panicles. The hue of the plant is a peculiarly fresh and pleasing green, and it forms an elegant object in the centre of a flower-bed or group with plants of like character. Raised from seed as easily as any half-hardy annual.

=*Artemisia gracilis.=--An exceedingly graceful plant, 3 or 4 ft. high, with leaves cut into very fine hair-like segments, having some resemblance to fennel or other umbelliferous plants with minutely-cut leaves, and of a deep grass-green, except in the hearts of the shoots, where the young leaves are unfolding, where there is a slight hoary pubescence. The flowers are in compound panicles, quite obscure, of a pale green, not at all ornamental in the common sense, but forming a not ungraceful inflorescence. However, the plant is only likely to be grown for its graceful foliage and habit, and the flowers, which only appear in autumn, may be pinched off if not admired. Similar positions to those recommended for the preceding species. Seed.

=*Arum crinitum.=--The appearance of this plant when in flower is very grotesque from the singular shape of its broad, speckled, contorted spathe. The leaves are divided into five or seven deep segments, the central division being much broader than the others, and the leaf-stalks, overlapping each other, form a sort of spurious stem a foot or 14 ins. high, marbled and spotted with purplish-black. The treatment for this plant is similar to that given for _A. Dracunculus_; but as it is rather more tender, it will require more care and shelter in winter. Warm borders, fringes of shrubberies, or beds of the smaller subtropical plants, will suit it best. The appearance of the flower is almost too repulsive for the nerves of some persons. Division. S. of Europe.

=*Arum Dracunculus.=--A strange-looking but handsome plant, with a white stem curiously marbled with black, about 3 ft. high, and very deeply cut palm-like leaves, broadly veined and spotted with white. The spathe is of a pale green colour on the outside and of a deep purple-violet within, and, as well as the flowers, exhales a powerful carrion odour. Requires a light, deep, and dry soil, and does best in half-shady positions. Easily multiplied by division in spring or autumn. It is best fitted for the fringes of shrubberies, etc., or among the vegetation that sometimes starts from the bottoms of warm walls. S. of Europe.

=*Arum italicum.=--This plant, which is a native of the Isle of Wight and the Channel Islands, resembles the common _A. maculatum_ in habit and in the shape of its leaves, which are, however, of a dark bluish-green colour, handsomely spotted with white, and marked with yellow veinings. Although it is a very hardy plant, and will thrive almost anywhere in moist soil and a shady position, it will be better to place it in sheltered positions along the sunny fronts of shrubberies, amidst low-spreading evergreens, and in cosy spots about the flanks of rock work and ferneries, to prevent its handsome foliage from being disfigured by cold wintry winds. One great merit of this is that it may be used to ornament positions in which few other plants will thrive,--as, for instance, under trees, groups of shrubs, etc. Easily multiplied by division in the end of summer and in autumn. S. of Europe.

=*Arundo conspicua.=--A companion for the Pampas grass, though by no means equal to it, as has been stated by some writers. In some very fine deep and free sandy loams it attains a height of nearly 12 ft., but this is rare. As a conservatory subject it is fine in flower, and it will be often seen in large conservatories after a few years. A large pot or tub will be necessary if it is grown indoors. The drooping foliage will always prove graceful, and it sends up long silvery plumes, drooping also, and strikingly beautiful. Judging by its different appearance when freely grown in a tub indoors, and when planted out even in favourable spots, my impression is that it by no means takes so kindly to our northern climate as the Pampas grass. However, it is well worth growing, even in districts where it does not attain a great development. It comes into flower before the Pampas grass, and may be considered as a sort of forerunner of that magnificent herb. New Zealand.

=*Arundo Donax.=--This great reed of the south of Europe is a very noble plant on good soils. In the south of England it forms canes 10 ft. high, and has a very distinct and striking aspect. It will grow higher than that if put in a rich deep soil in a favoured locality; and those who so plant clumps of it on the turf in their pleasure-grounds will not be disappointed at the result. Nothing can be finer than the aspect of this plant when allowed to spread out into a mass on the turf of the flower-garden or pleasure-ground. It seems much to prefer deep sandy soils to heavy ones; indeed, I have known it refuse to grow on heavy clay soil, and flourish most luxuriantly on a deep sandy loam in the same district. Like all large-leaved plants, it loves shelter. No garden or pleasure-ground in the southern parts of England and Ireland should be without a tuft of it in a sheltered spot. But, fine as it is for effect and distinctness, its variegated variety is of more value for the flower-garden proper.

=*Arundo Donax versicolor.=--We have already noticed several fine things for grouping together, or for standing alone on the turf and near the margin of a shrubbery-border, and this is as well suited for close association with the choicest bedding-flowers as an Adiantum frond is with a bouquet. It will be found hardy in the southern counties, and, considerably north of London, may be saved by a little mound of cocoa-fibre, sifted coal-ashes, or any like material that may be at hand. In consequence of its effective variegation, it never assumes a large development, like the green or normal form of the species, but keeps dwarf, and yet thoroughly graceful. It is of course best suited for warm, free, and good soils, and abhors clay, though it is quite possible to grow it even on that with a little attention to the preparation of the ground. But it is in all cases better to avoid things that will not grow freely and gracefully on whatever soil we may have to deal with: and it is to those having gardens on good sandy soils, and in the warmer parts of England, that I would specially recommend this grand variegated subject. For a centre to a circular bed nothing can surpass it in the summer and autumn flower-garden, while numerous other charming uses may be made of it. Not the least happy of these would be to plant a tuft of it on the green turf, in a warm spot, near a group of choice shrubs, to help, with many other things named, to fill up the gap that is now nearly everywhere observed between ordinary fleeting flowers and the taller tree and shrub vegetation. It is better to leave the plant in the ground, in a permanent position, than to take it up annually. Protect the roots in the winter, whether it be planted in the middle of a flower-bed or by itself in a little circle on the grass. Increased by placing a shoot or stem in a tank of water, when little plants with roots will soon start from every joint; they should be cut off, potted, and placed in frames, where they will soon become strong enough for planting out.

=*Arundo Phragmites= (_Common Reed_).--A native marsh-or water-plant, 5 ft. or 6 ft. high, bearing when in flower a large, handsome, spreading, purplish panicle. The stems are smooth, simple, very erect, and grow closely together. The plant is only attractive when in flower, as its flat, ribbon-like leaves do not of themselves present any very striking appearance. Useful for the margins of artificial waters, etc., to which it may be brought from its wild haunts. It should, however, if possible, be kept in one spot and not allowed to spread too much.

=*Asclepias Cornuti.=--A handsome hardy perennial from N. America, sending up from its running, underground rootstock a number of erect, unbranched stems, from 4 ft. to 6½ ft. high, thickly covered with large opposite oval leaves. The flowers are of a light rose-colour, and agreeably fragrant, and are borne in large umbels at the tops of the stems. The plant does well in almost any kind of soil or position, and is well adapted for planting in places which do not require much attention. As it spreads very rapidly at the root, it is better to exclude it from small beds or gardens, which would soon be overrun by it. Several other species are in cultivation, the best of which are _A. speciosa_ (Douglasii), _A. incarnata_, and _A. tuberosa_.

=*Asparagus Broussoneti= (_Giant Asparagus_).--A vigorous, climbing asparagus, with a tapering, shrubby stem, 10 or 12 ft. high. The flowers are small and inconspicuous, and are followed by numerous small red berries. An excellent subject for tall trellises, rustic bowers, stumps of trees, tall poles, etc. Canary Islands.

=Asplenium Nidus-avis.=--This is a remarkable fern, which has been placed out of doors in the garden in summer, from early in June to October; but it is not vigorous or hardy enough to be generally recommended for this purpose. However, as it may have been noticed in abundance at Battersea Park, I allude to it here. The leaves are rather broad, pointed, and undulating, nearly 3 ft. long, and form roundish, spreading, nest-like tufts. It is a favourite subject in places where large collections of tropical ferns are grown, and in such places a plant may be tried in the open air in a very warm, shady, and perfectly sheltered position. E. Indies.

=*Astilbe rivularis.=--A large-leaved and striking plant from Nepaul, with the habit and general appearance of a _Spiræa_, growing to a height of more than 3 ft., and of a free and graceful habit, which makes it useful for association with the finer-foliaged herbaceous plants, and for dotting here and there in the wild or picturesque garden. It keeps its foliage well through the season, unlike some herbaceous plants, and is therefore all the more valuable. Flowers late in summer, small, yellowish-white, in large panicled spikes. The radical leaves are broad, twice ternate with toothed divisions, and the base of the leaf-stalk is covered with numerous rough tawny hairs. Being pretty hardy, the Astilbe usually succeeds well in any cool rich soil, and best in half-shaded positions. Easily multiplied by division. It is suited for isolation, borders, fringes of shrubberies, or for groups of hardy plants.

*=Astilbe rubra.=--A very pretty and hardy plant, also resembling a. _Spiræa_ in habit and appearance, and growing from 4 ft. to 6 ft. high. The leaves are twice ternate, with oblique, heart-shaped leaflets, 1 in. to 2 ins. long, and with lengthened serrated points. The flowers are numerous, in dense panicles, and of a rose-colour, appearing late in summer and in autumn. The same positions, etc., as those for the preceding kind. North America, Japan, and mountains of Northern India.

=*Bambusa.=--I wish to call the attention of all horticulturists who live in the southern and more favoured parts of these islands to the fact that there are several bamboos and bamboo-like plants from rather cool countries that are well worth planting. Nothing can exceed the grace of a bamboo of any kind if freely grown; but if starved in a crowded house, or grown in a cold dry place, where the graceful shoots cannot arch forth in all their native beauty, nothing can be more miserable in aspect. In cold bad soils and exposed dry places in the British Isles these bamboos have little chance; but, on the other hand, they will be found to make most graceful objects in many a sheltered nook in the south and southwestern parts of England and Ireland. We have some knowledge of the capabilities of one kind in this country. In a well-sheltered moist spot at Bicton I have seen _Bambusa falcata_ send up young shoots, long and graceful, like the slenderest of fishing-rods, while the older ones were branched into a beautiful mass of light foliage of a distinct type. The same plant grows in the county of Cork to a height of nearly 20 ft. This is the best known kind we have. At Paris I was fortunate enough to observe various other kinds doing very well indeed, although the climate is not so suitable as that of Cork or Devon. These were _Bambusa edulis_, _aurea_, _nigra_, _Simonii_, _mitis_, _Metake_, and _viridi-glaucescens_, the first and last of this group being very free and good. All the others will prove hardy in the south of England and Ireland, though, as some of them have not yet been tried there, it requires the test of actual experiment. Those who wish to begin cautiously had better take _B. Simonii_, _viridi-glaucescens_, and _edulis_ to commence with, as they are the most certainly hardy, so far as I have observed. The best way to treat any of these plants, obtained in summer or autumn, would be to grow them in a cool frame or pit till the end of April, then harden them off for a fortnight or so, and plant out in a nice warm spot, sheltered also, with good free soil--taking care that the roots are carefully spread out, and giving a good free watering to settle the soil. There are no plants more worthy of attention than these where the climate is at all favourable, and there are numerous moist nooks near the sea-side where they will be found to grow most satisfactorily, as well as in the south.

=*Bambusa aurea.=--A very hardy and graceful Chinese species, differing but slightly from _B. viridi-glaucescens_ in size and habit, and forming elegant tufts with its slender much-branched stems, which attain a height of from 6½ ft. to 10 ft., and are of a light-green colour when

Thriving in warm and mild southern districts.]

young, changing into a yellowish hue, and finally becoming of a straw-yellow when fully grown. The leaves are lance-shaped acute, light green, and are distinguished from those of _B. viridi-glaucescens_ by having their under surface less glaucescent, and the sheath always devoid of the long silky hairs. The preliminary remarks on culture, etc., will apply to all the species here described.

=*Bambusa edulis.=--A hardy and vigorous kind, with very elegant light-green shoots and olive-green stems, attaining a height of 10 ft. in the neighbourhood of Paris. The leaves are small, and the plant is not nearly so branching as in some other kinds.

=*Bambusa falcata= (_Arundinaria falcata_).--A very ornamental species from Nepaul and the Himalayas, and at present the only kind of bamboo much planted with us. It grows from 7 ft. to 20 ft. high, and has woody, twisted, smooth stems of a yellowish-green or straw-colour, knotty, bearing on one side of each of the knots a bundle of small branches equally knotty and twisted. The whole plant has a pale yellowish hue, except in the young spikelets and sheaths, which are occasionally purplish. The leaves are of a fine delicate green, from 4 ins. to 6 ins. long, ribbon-like, linear-acute, sickle-shaped, in two rows, short-stalked, and sheathing. It is hardy over the greater part of England and Ireland, but only attains full development in the south and west. I have seen it attain great luxuriance in Devon, and nearly 20 ft. high near Cork, though in many districts it is stunted. It loves a deep, sandy, and rich soil, and plenty of moisture when growing fast.

=*Bambusa Fortunei.=--A pretty dwarf variegated species from Japan, of which I have not seen the green form in cultivation, with very dwarf, slender, branching, hollow, half-shrubby stems, seldom growing more than 18 ins. high, and with very short internodes. The leaves are 3½ ins. to 8 ins. long, linear-lance-shaped, abruptly pointed, somewhat rounded at the base, serrated and often fringed with long hairs on the margin, downy on both sides; they are distinctly variegated, the transverse veins being often of a bottle-green colour; stalks very short and hairy. This kind has proved hardy in our gardens, but it has not the charm of grace possessed by the other kinds, and is chiefly desirable in collections of variegated and edging plants.

=*Bambusa japonica= (_B. Metake_).--A large-leaved and rather dwarf species from Japan, growing from 4 ft. to 7 ft. high, with erect thickly-tufted stems, which are entirely covered by the sheaths of the leaves; the branches are also erect. The leaves are lance-shaped, with a very sharp point, dark green, persistent, narrowed into a short leaf-stalk, and nearly a foot long. This species sometimes flowers with extraordinary profusion at the expense of a portion of the foliage, which withers away and leaves the naked stems exposed. This may, however, be prevented to some extent, by placing the plants on mounds somewhat above the level of the surrounding soil. I have seen it thrive very freely in the late Mr. Borrer’s garden in Sussex, and in one or two other places. It loves a peat soil, or a very free moist and deep loam, and runs a good deal at the root.

=Bambusa mitis.=--A fine and vigorous kind from Cochin China, somewhat tenderer than most of the other

Hardy Bamboo Section; growing 16 to 20 feet high in the milder southern parts of England and Ireland.]

kinds enumerated, though no doubt it will be found to thrive in the milder southern districts; or it may be found useful if grown in the conservatory in winter and placed out in the open air in summer, as is sometimes done with _B. arundinacea_, which otherwise could not possibly be seen out of doors in our climate. Panicle simple, erect, close; spikes long, imbricated. Leaves rather large, lance-shaped, striated, clasping the stem, which is woody and tapering; nodes rather distant, and not very prominent.

=*Bambusa nigra.=--A rather compact-growing Chinese kind, with nearly solid stems, and thinner leaves than those of any other species. The stems are smooth and bushy, about 7 ft. high, of a light green, dotted and striped with purple when young, changing to a glistening black when fully grown; they branch very much at the top, and sometimes from the base up. The leaves are oval-oblong, acute, shortly-stalked, with a hard, dry, persistent sheath; their tender green colour contrasting finely with the blackish hue of the stems. It is best planted as isolated specimens near the margins of shrubberies, or on slopes in the pleasure-ground in warm, sunny, and sheltered positions, in deep, sandy, and well-drained soil.

=*Bambusa Quilioi.=--A Japanese species of vigorous growth, with robust green stems and bright-green leaves, polished above and slightly mealy beneath, the ligule bearing a little bundle of brownish-grey hairs at the top. This kind I first saw in the gardens of the Acclimatisation Society at Paris, where it was thriving vigorously, and I have little doubt of its proving valuable in Britain.

=*Bambusa Simonii.=--A handsome, distinct, and vigorous species, which has grown very freely for some years past in the neighbourhood of Paris. The stems are numerous and grow as much as 10 ft. high in a season. They are mealy-glaucous at the joints, and the branchlets are numerous and rather closely crowded. The leaves are narrow, sometimes nearly a foot long, and are occasionally striped with white. This species, which was obtained from China some years since, has thriven very well in the gardens at Paris, where M. Carrière first drew my attention to it. From what I have seen it do there I have no doubt it will prove of great value in the milder southern parts of England and Ireland.

=*Bambusa violascens.=--A hardy and vigorous kind, intermediate between _B. nigra_ and _B. viridi-glaucescens_, most resembling the last-mentioned however. It has blackish-violet much-branched stems, which assume a yellow tinge with age. The leaves are green above, bluish-grey beneath, with an elongated ligule surrounded by a bundle of black hairs. Native of China.

=*Bambusa viridi-glaucescens.=--A species from Northern China, which has been proved very hardy and free in the Paris gardens, and will, probably, in warm parts of our islands, make a more vigorous growth and prove a more beautiful object than any other kind. The stems, of a light-yellowish-green, grow from 7 ft. to 12 ft. high, branching from the base, each branch again branching very much. The leaves are very numerous, especially at the ends of the branches, of a pale-green, bluish underneath, sheathing the stem for a considerable length. It forms a fine object when planted as isolated specimens in sheltered warm glades in the pleasure-ground, or in snug open spots near wood-walks, in very deep, rich, light, and well-drained soil.

=*Bambusa viridis striata.=--Described as a vigorous-growing, hardy kind, with numerous branches, having its long leaves green on both sides, and marked with bands, some of a yellowish and others of a deeper green. It is a native of Japan, and was recommended by MM. Thibaut and Ketteleer of Paris, but I have had no experience of its growth.

=*Baptisia australis.=--A handsome hardy perennial from N. America, forming strong bushy tufts from 3 ft. to 5 ft. high, and from 3 ft. to 6 ft. across, with sea-green trifoliate leaves which reflect a metallic lustre. The flowers are of a delicate blue, with wings of a greenish-white colour, and are borne in long erect spikes. Grows well in ordinary, deep, well-drained soil, preferring a sandy loam. _B. exaltata_ and _B. alba_ are closely allied to the preceding species, and form equally handsome bushes. The foliage of these is of a character to permit of their being grouped along with some of the finer perennial foliage-plants with good effect. Division.

=*Berberis Aquifolium.=--A well-known shrub from N. America, with simple stems from 3¼ ft. to 6½ ft. high, and very glistening, bright green leaves, each consisting of 7 or 9 sessile, oval, spiny leaflets. Where the plant is fully exposed to the sun, the foliage frequently acquires an agreeable reddish tinge. There are numerous varieties, of which _B. floribunda_ may be mentioned as very handsome in habit and profuse in flower, and _B. nitens_, remarkable for the extremely glossy appearance of the old leaves, which when young are of a rich bronze changing to a dark green. This variety is of a dwarf and compact habit. It requires a shady situation and a compost of peat, loam, and sand. Though so very common, it will be found worth planting in some places among groups of hardy things, and also for isolation on the turf, its leaves being very ornamental.
