Chapter IV: Preface (4)

This is a charming kind, seldom seen and, perhaps, little known; the name would imply that it is a variety having equal traits of two other forms. It blooms in January and the flowers appear without any foliage. So well is the Crocus known, it will only be needful to state the more striking features of the one under notice.

The flowers are produced on tubes 3in. to 5in. long, and stoutly formed; the colour is a shaded lilac-purple, striped with darker lines; the petals or divisions of the perianth are 1½in. long and ½in. broad, shining or satiny, and become well expanded during the short moments of winter sunshine; the stamens are half the length of perianth, of a fine deep orange colour, and covered with a thick coat of pollen all their visible length. In rich contrast with these is the style, with its tuft of filaments of a bright orange scarlet colour. From this description it will be seen that the flower is a rather small Crocus, but from the soft tints of the perianth, and more pronounced and bright colours of the seed organs, it is one of much beauty. These features, added to the facts of the bloom appearing in winter and having the scent of wild roses, are sure to render it a favourite kind wherever grown. The leaves are short and narrow, almost grassy.

It enjoys a light but rich loam and sunny aspect, and increases itself freely by offsets of the matured corms, clumps of which may be divided after the foliage has withered.

Flowering period, January.

Cyananthus Lobatus.

_Nat. Ord._ POLEMONACEÆ.

A small plant with a large flower, a veritable gem; no collection of choice alpines can be complete without this species. A native of Chinese Tartary, brought to this country in 1844, where it proves perfectly hardy in the most exposed parts of the open garden; it is herbaceous and perennial; its large and brilliant flowers are very beautiful, but all its other parts are small, as may be seen in the illustration (Fig. 31). It is seldom met with except in collections of rare plants, but there is no reason why it should not be more commonly grown, as its requirements are now well understood. It is not a showy subject, but, when examined, it proves of exquisite beauty.

The flowers are of a bright purple-blue colour, over an inch across, the petals being of good substance, tongue-shaped, and falling backwards, when the china-like whiteness about the top of the tube becomes more exposed; the calyx is very large, nearly egg-shaped, having five finely-pointed and deeply-cut segments; the bulky-looking part, which has an inflated appearance, is neatly set on a slender stem, and densely furnished with short black hairs of even length; this dusky coat has a changeable effect, and adds not only to the character, but also to the beauty of the flower. The small attenuated leaves are alternate and laxly arranged on the flower stems, which are 6in. to 12in. long, round, and nearly red. Each leaf is less than 1in. long, distinctly lobed with five or more lobes, and all the edges are turned back, causing the foliage to appear thick and well finished; the foliage of the stems not bearing flowers is more closely set. The habit of the plant is procumbent; stems contorted, and producing solitary flowers.

(Natural size.)]

It should be grown on rockwork, where its stems can nestle between the stones and its roots find plenty of moisture, as in a dip or hollowed part; the long and fleshy roots love to run in damp leaf mould and sand. The position should be open and sunny, in order to have flowers. Cuttings may be taken during summer, and struck in sandy peat kept moist, or strong roots may be divided. The latter method is the less desirable, not only because of jeopardising the parent stock but also because strong roots show to greater advantage when not separated.

Flowering period, September and October.

Cypripedium Calceolus.

ENGLISH LADY'S SLIPPER; _Nat. Ord._ ORCHIDACEÆ.

This well-known terrestrial orchid is a rare British plant, very beautiful, and much admired, so much so, indeed, that many desire to grow it. It happens, however, that it seldom thrives under cultural treatment, and seems to prefer a home of its own selection, but its habitats are said now to be very few in Great Britain, it having been hunted out and grubbed up everywhere. Fortunately, it can be grown in gardens, and in good form, though rarely seen thus. To see well-grown flowers of this orchid either makes us feel more contented with our own climate or strongly reminds us of others where the most gorgeous varieties of flowers and fruit grow wild. It is large and striking, fragrant, and very beautiful; no one can see it, especially in a growing state, without being charmed by its freshness and simplicity; it also forms one of the finest specimens for the student in botany, and in every way it is a plant and flower of the highest merit (see Fig. 32). It should be in all collections of choice plants, and every amateur should persevere until he succeeds in establishing it.

(One-third natural size.)]

Under cultivation it flowers in early May, at a height of 9in. to 12in.; the flowers are composed of a calyx of three brownish-purple sepals, which have only the appearance of two, from the fact of the lower two being joined or grown together, and even so combined they are somewhat less than the upper sepal. The division may be observed at the tips, though in some specimens it is microscopic--in the one now by me it is hardly the eighth of an inch. Two petals; these are cross-form in relation to the sepals, of the same colour, and a little longer--about 2in.--narrow, drooping, pointed, and slightly twisted when a few days old; lip, "blown out like a slipper," shorter than the sepals, compressed, richly veined, and lemon yellow. The seed organs are curious, the stigma being foot-stalked, peltate, and placed between and above the anthers. The leaves are pale green, very hairy, many-ribbed, stem-clasping, alternate, ovate, and slightly wavy; the lower ones are 5in. or 6in. long and 2in. to 3in. wide, and pointed. The root is creeping, the fibres stout, long, wiry, and bent. During spring the plant makes rapid growth, and seldom bears more than one flower; for the first time a plant produced two with me in 1882. They are sweetly scented, like the primrose.

Many amateurs, who have otherwise proved their knowledge of the requirements of plants by growing large and choice collections, have failed to establish this after many trials; and were it not for the fact that with me it is growing in various positions and under different modes of treatment, and that it has so grown for several years, I think I should not have ventured to give hints to experienced horticulturists. In my opinion, four conditions are strictly necessary in order to establish this native orchid in our garden: (1) A strong specimen with a goodly portion of the rhizoma attached; (2) Firm or solid planting during autumn; (3) Moist situation; (4) Shade from the mid-day sun. Further information may be best given by stating the _modus operandi_: Several years ago a number of good roots were planted in sandy loam of a calcareous nature. They were put in somewhat deeply, the roots carefully spread out, and the soil made solid by repeated waterings, the position being shaded by an apple tree. They are now well established, and only receive a top dressing of leaves and manure to keep them cool and moist in summer. At the same time a number were potted deeply in loam, peat, and broken oyster shells; when filling in the compost, it, too, was washed to the roots, so as to make all solid by frequent applications; the pots have always been kept in cool and shady quarters, and plunged; they bloom well every season. I have likewise found another plan to answer well. In a moist corner make up a low-lying bed of sand and peat, mostly sand, plant 9in. deep, and make all solid, as before, by water. When the growths appear on the surface, water with weak liquid manure, and if shade does not exist from the mid-day sun, some should be provided; in this way I am now growing my finest specimens; but if once the roots become dry, the plants will suffer a serious check. I feel equally confident that the roots enjoy a firm bed, but it should be of such material that they can freely run in it.

Flowering period, May and June.

Daphne Cneorum.

TRAILING DAPHNE; _Common and Poetical Name_, GARLAND FLOWER; _Nat. Ord._ THYMELACEÆ.

An alpine shrub from Austria; dwarf, evergreen, and having a tendency to creep. It is deservedly a great favourite; it wins admiration by its neat and compact form and its dense and numerous half-globular heads of rosy pink flowers, which are exceedingly fragrant, in the way of the old clove carnation, but more full.

(One-fourth natural size; (1) flower, full size.)]

The flower buds are formed during the previous season of growth, like those of the rhododendron; for many days before the flowers open the buds have a very pleasing appearance, being closely packed and coral-like; when all the florets are expanded they form a half-globular head 1in. to 1½in. across, being of a lively pink colour. The flowers are composed of a tubular calyx, four-parted; leaves inversely ovate, lanceolate, pointed, and entire; about an inch long, and narrow; of a dark green colour and much substance, being arranged in circular form on the round and somewhat wiry, tough stems, which in time become very long and bare.

In order to grow this shrub well, three conditions are needful, viz., a moderately pure atmosphere, exposure to full sunshine, and plenty of moisture; it also prefers peat or vegetable soil, but this is not strictly needful if the other conditions are present. I have grown the specimen, from part of which the illustration (Fig. 33) was drawn, for four years in rich loam, without a particle of peat, but the roots have been protected against drought by large stones at the base of small rockwork. Doubtless, peat, where it is plentiful, used in addition to the above compost, would prove beneficial. After a few years' growth in one position, bushes which have become long and bare in the stems may be transplanted with advantage, laying in the stems to a moderate depth, from which new roots will issue the first season; this is also the readiest way of propagation. February or September would be suitable months for such operation, but the latter would probably interfere with its flowering at that time, when frequently a second but spare crop is produced.

Flowering periods, April and May, and again in September.

Daphne Mezereum.

MEZEREON; _Old Names_, SPURGE-FLAX, GERMAN OLIVE-SPURGE, _and_ DWARF BAY; _Nat. Ord._ THYMELACEÆ.

This is a dwarf deciduous shrub, which produces its welcome flowers in great abundance whilst bare of leaves; it is a British species, though not occurring generally, yet it is pretty well known from its extensive cultivation as a garden shrub. The flowers are very desirable, from the way in which they are produced in knotted clusters on the long stems; they appear in winter; moreover, they are of a hardy and durable nature and very sweetly scented. As a shrub it is very suitable for any sized garden, being dwarf--2ft. to 4ft. In some parts it is a general favourite, and may be seen in almost every garden; such patronage is well merited, as it not only enlivens the garden at a dead season, but it heralds spring time and furnishes long sprigs of wallflower-scented blossom as cut bloom, which shows to advantage by gaslight.

There are interesting facts in connection with this shrub that add to its charm. It was esteemed of old of great virtue; all its parts are hot and biting, more especially the berries, of which it was said that "if a drunkard do eate--he cannot be allured to drinke any drinke at that time: such will be the heate of his mouth and choking in the throte." Its wood is very soft and tough, and cannot easily be broken; this, however is a quality common to the genus. The berries are poisonous to man, but birds are so fond of them that they are rarely allowed to become ripe, at least, such is the case near towns. The seeds of this and allied species are used in the South of Europe as a yellow dye for wool. From its importance, the shrub has been long and widely known, and both its botanical and common names are numerous; for these, however, the reader may not care. It is seldom called by any other than its specific name, Mezereon, which Gerarde describes as English-Dutch.

Its flowers, which are purple, come on the otherwise naked stems of last season's growth, lateral fashion, in threes mostly, and sometimes the blossomed stems will be over a foot in length; the flowers are ½in. long, sessile and funnel-shaped; the limb four-cut; sweet smelling and very durable. The berries are the size of a small pea, bright green at first, then turning to red, and ultimately to a nearly black colour. The leaves--lance-shaped, smooth, and deciduous--appear after the flowers. The habit is branched and erect, forming neat bushes. In a wild state it flowers in March and April, but under cultivation it is much earlier.

In the garden it may be planted under other trees, where it proves one of a scarce class of shade-loving flowering shrubs; it also does well in open quarters. In gardens, where its fruit is unmolested, it is, perhaps, more attractive than when in blossom, as then the foliage adds to its beauty. The flowers in a cut state are serviceable, pretty, and desirable from their sweetness; long sprigs mixed with lavender or rosemary form a winter bouquet not to be despised; or, it may be placed in a vase, with a few small-leaved ivy trails and a spray of evergreen bamboo (Metake). Gerarde's description of this shrub will, doubtless, be read with interest: "The braunches be tough, limber, and easie to bend, very soft to be cut; whereon do grow long leaves like those of priuet, but thicker and fatter. The flowers come foorth before the leaves, oftentimes in the moneth of Januarie, clustering togither about the stalks at certain distances, of a whitish colour tending to purple, and of a most fragrant and pleasant sweet smell. After come the smal berries--of an exceeding hot and burning taste, inflaming the mouth and throte of those that do taste thereof, with danger of choking."

Flowering period, February to April.

There is a variety called _D. M. album_; the only difference from the typical form is implied by the name, the flowers being white. It also is in bloom at the same time as the species.

_D. M. autumnale_ is another variety, which, however, blooms in the autumn; the flowers are red; it is a native of Europe.

These shrubs enjoy a light but moist soil of a vegetable nature, but they also thrive in a sandy loam. They may be increased by seed, or, more quickly, by grafting on stocks of spurge laurel; cuttings may be rooted, but are uncertain.

Dentaria Digitata.

TOOTHWORT; _Nat. Ord._ CRUCIFERÆ.

A hardy, tuberous perennial, native of Switzerland, but long cultivated in British gardens, and decidedly "old-fashioned."

Imagine a spray of pale purple wallflower, and that will give some idea of the form and colour of its flowers, which are produced on round wiry stems, nearly a foot high, in terminal racemes. The leaves, which are produced mostly in threes on a stem, have a channelled petiole, and, as the specific name denotes, are spread out like fingers, mostly of five parts; a five-cut leaf of a Christmas rose will give a fair notion of the form, but the Toothwort leaves are less, not so thick, and more herb-like than the hellebore; they are also finely, deeply, but irregularly toothed. The roots are of singular form, almost like human teeth, arranged as scales, whence the name Toothwort. Its first appearance above ground is in February, when the young growths are bent or folded like those of the anemone, and in genial seasons it will flower early in March.

It loves both a little shade and moisture. I grow it at the base of a bit of rockwork, in black or leaf mould; the aspect is south-east, but an old sun-dial screens it from the mid-day sun. The whole plant has a somewhat quaint appearance, but it has proved a great favourite. When the tops have died down the roots can safely be lifted, cut in lengths of one or two inches, and then replanted. It also produces seed freely, but from the easy method of increase by root division, I have not had occasion to experiment with seed.

Flowering period, March to May.

Dianthus Deltoides.

MAIDEN PINK; _Old Names_, "WILD GILLOFLOWER," "VIRGIN-LIKE PINKE," "MAIDENLY PINKE"; _Nat. Ord._ CARYOPHYLLACEÆ--SILENACEÆ.

A British species of perennial character, never failing to bloom for a long period when it meets with a suitable home in our gardens--as in positions similar to those described for _Erysimum pumilum_. Seen either wild or in gardens it is much admired; it bears but simple flowers, but therein consists its beauty.

As Gerarde says, "Virgin-like Pinke is like unto the rest of the garden pinkes in stalkes, leaves, and rootes. The flowers are of a blush colour, whereof it tooke his name, which sheweth the difference from the other." It is about the most simple form of the Pink tribe. The flowers are a little over ½in. across, of a rose colour or pleasing blush. It grows nearly a foot high in some soils, but in a poor compost it is more dwarf and floriferous. The flower stems are much divided near the tops, and capable of producing a good effect from their numbers of bright flowers. The leaves are small, scarcely 1in. long, linear, lance-shaped, and of a dark green colour; they are closely arranged on decumbent stems, which sometimes are more than 1ft. long. The habit is compact, both as regards leaves, stems, and flowers.

For all such places as afford dryness at the roots this is a suitable plant as a constant bloomer of effective colour. When once it has become established it seeds freely, and the young plants may be seen in the walks for yards around the parent stock. It is one of those happy subjects that can take care of themselves, either braving its enemies or having none.

In its wild state it blooms from the sixth to the tenth month, both inclusive; but with cultural attention and during favourable winters, it has been seen in flower to the end of the year.

Flowering period, June to October.

Dianthus Hybridus.

_Syn._ D. MULTIFLORUS; MULE PINK; _Nat. Ord._ CARYOPHYLLACEÆ.

Hardy and evergreen. The specific name of this variety is not at all descriptive, and it may be better to at once give its common name of Mule Pink, of which there are various colours, as bright scarlet, rose and pure white, all very double and neat flowers.

It is the double rose kind which has induced me to speak of this section of the Pink and Sweetwilliam family. I dare say many will be surprised when I state that my strongest plant of this has been in flower more than two years. Severe as the 1881 winter was, when the plant was clear of snow it was seen to have both flowers and buds--in fact, for two years it has flowered unceasingly; the other varieties are not such persistent bloomers. The genus to which these hybrids belong is very numerous, and includes Carnations, Picotees, garden and alpine Pinks and Sweetwilliams. They are all remarkable for their fresh green and glaucous foliage and handsome flowers. Some species or varieties are amongst the "old-fashioned" garden plants of Parkinson's time, and all are characterised by an exquisite perfume. The Latin name of this genus is a very happy one, meaning "divine flower," in reference to its fragrance. Nearly every form and colour of Dianthus are popular favourites, and hardly any garden is without some of them.

The Mule Pink is supposed to have been produced from _D. barbatus_ and _D. plumarius_; be that as it may, the features of both are distinctly seen in it: the colour and partial form of the foliage, the form of stems, and clustered arrangement of the buds much resemble _D. barbatus_ or Sweetwilliam; whilst the stout reflexed and pointed features of the leaves, and the general form of the small but double flowers resemble _D. plumarius_, or the garden Pink. To this description of _D. hybridus_ I will only add that in both foliage and flowers there is more substance than in either of its reputed parents, and the habit of the plant is semi-trailing or procumbent, as seen in specimens three years old. It is rather more difficult to grow than the common Pink. Any position or soil will not answer; it does well on rockwork, where it can hardly suffer from damp, so much disliked by all the genus; but if thus planted, it should be where its thickly-foliaged stems cannot be turned over and wrenched by strong winds. It may be grown in borders in sandy loam; and if such borders are well drained, as they always should be for choice flowers, there will be little to fear as to its thriving. Such an excellent flower, which, moreover, is perpetually produced, deserves some extra care, though, beyond the requirements already mentioned, it will give very little trouble.

To increase it, the readiest way is to layer the shoots about midsummer, half cutting through the stems, as for Carnations; thus treated, nice plants will be formed by October, when they may be lifted and transplanted to their blooming quarters; and I may here state that a line of it, when in flower, is richly effective. A good style also is to make a bold clump by setting ten or twelve plants 9in. apart. Another mode of propagation is to take cuttings at midsummer and dibble them into boxes of leaf soil and sand. Keep them shaded and rather close for a week or more. If the boxes could be placed in a cucumber frame, the bottom heat and moisture would be a great help to them. The object to aim at should be not only to root the cuttings, but to grow them on to fair-sized plants for putting out in the autumn. To do this, when the cuttings are rooted they should be planted 6in. apart in a bed made up of well decayed manure and sand, in which it will be seen that they will make plenty of roots and become sturdy plants. The wireworm and slugs are both very fond of Pinks and Carnations. Slugs should be trapped, but the wireworm, unfortunately, has often done the mischief before we become aware of its presence, and even then it is a troublesome pest to get rid of. I find nothing more useful than stirring and digging the soil as soon as there is room to work with a spade or fork; the worm cannot endure frequent disturbance, and such operations are otherwise beneficial to the plants.

Flowering period, May to September.

Dodecatheon Jeffreyanum.

_Nat. Ord._ PRIMULACEÆ.

This is a distinct and noble species. The older leaves are more spoon-shaped, at least a foot long, rather narrow, not toothed, of a reddish colour at the base, and the mid-rib pale green, almost straw-colour; the flower scape is also reddish, but the flowers are fewer. As a foliage plant this species is very effective.

All the Dodecatheons make a rapid growth in spring, their scapes being developed with the leaves; the genus will continue in flower for two months, after which time, however, their foliage begins to dry up. They should, therefore, be planted with other subjects of later growth and blooming, so as to avoid blank spaces. The overshading foliage of other things will do them no harm, as it will be only for a season. The position should be moist and somewhat sheltered from high winds, or the stout and tender flower stems will be snapped off. The soil should be of a vegetable character and retentive of moisture. My specimens are grown in leaf soil and loam, in a dip of small rockwork. All the kinds were planted that a large flat stone, which we had ready, would so fit to, or over, them as to secure their roots against drought. This I find a good plan with moisture-loving subjects, where suitable positions are not otherwise readily offered. Besides, the varieties so grown have a pleasing appearance, and for purposes of comparison are very handy. Their propagation is easy. The crowns may be divided either in spring or autumn, the latter being the best time, as then probably each piece will flower the following spring.

Flowering period, April to June.

Dodecatheon Meadia.

SHOOTING STAR, _or_ AMERICAN COWSLIP; _Nat. Ord._ PRIMULACEÆ.

A distinct and pretty herbaceous perennial, very hardy and floriferous. Those who do not readily recognise it by any of the above names, may do so by the illustration (Fig. 34). It has long been grown in English gardens--nearly 150 years--its habitat being North America. Not only does it do well in this climate, but since its introduction several improved varieties of this species have been produced, which are both good and distinct. A brief notice of them will not be out of place here, but first the general description may as well be given.

(One-sixth natural size.)]

The flowers much resemble the Cyclamen, but they are only about one-fourth the size; the calyx is five-parted; the corolla has five stout petals inserted in the tube of calyx; they are well reflexed and rather twisted; their colour is purplish-lilac, but at the base of the petals there is a rich blending of maroon and yellow. The seed organs are very long, compact, and pointed, giving the appearance of shooting stars. The flowers are arranged in fine clusters on a scape more than a foot high, each flower having a rather long, wiry, and gracefully bending pedicel; all of them spring from one centre. The leaves are radical, oblong, smooth, dented, and wavy, about 8in. long and nearly 3in. broad.

_D. M. albiflorum_ I do not grow, but from what I remember of it, it differs from the above only in being less vigorous and in having white flowers.

_D. M. elegans_.--Shorter and broader in leaf, and roundly toothed; flower stems shorter, umbels more numerously flowered, bloom deeper in colour.

_D. M. giganteum_ has a very large leaf, much larger than the typical form of the species, and of a pale green colour, and in all other respects it is larger, being also more than a week earlier in flower.

Flowering period, April to June.

Dondia Epipactis.

_Syns._ ASTRANTIA EPIPACTIS _and_ HACQUETIA EPIPACTIS; _Nat. Ord._ UMBELLIFERÆ.

This is a little gem, perhaps rather overdone with too many big names; still, this choice, hardy, herbaceous perennial is worth knowing by all its titles. Never more than 6in. high, its singular flowers are very attractive; they spring from the ground almost abruptly, are greenish-yellow and leafy in appearance--in fact, what at first sight might seem to be the petals are really but whorled bracts, which embrace the tiny umbels of flowers. Soon after the flowers the leaves begin to appear, unfolding like many of the anemones, each one springing from the root only; they also are of a peculiar colour and shape, being three-lobed and finely notched.

It will stand any amount of rough weather, always having a fresh appearance when above ground. It forms a choice specimen for pot culture in cold frames or amongst select rock plants; it should be grown in mostly vegetable mould, as peat or leaf mould, and have a moist position. Not only is it a slow-growing subject, but it is impatient of being disturbed; its propagation should therefore only be undertaken in the case of strong and healthy clumps, which are best divided before growth commences in February.

Flowering period, April and May.

Doronicum Caucasicum.

LEOPARD'S-BANE; _Syn._ D. ORIENTALE; _Nat. Ord._ COMPOSITÆ.

The specific name denotes sufficiently whence this comes. It is hardy, herbaceous, and perennial, and one of those plants which deserves to be in every garden; its general appearance is that of a tender plant, from the pale but fine delicate green of its foliage, a somewhat uncommon shade for so early a season. It begins to flower in March in a warm situation in the garden, when only a few inches high, and it goes on growing and flowering until summer, when it is nearly 2ft. high. A glance at Fig. 35 will give a fair idea of its habit.

(One-third natural size.)]

The flowers, which are bright yellow, are 2½in. across, produced one at a time, though the leafy stems are well supplied with buds in various stages of development. The leaves, besides being so rich in colour, are of handsome forms, being variously shaped, some having long stalks, others none; all are finely toothed and heart-shaped; the radical ones come well out and form a good base, from which the flower stems rise, and they in their turn serve to display the richly veined and ample foliage which clasps them to near their tops. Although this species is not a very old plant in English gardens, it belongs to a genus, several species of which are very "old-fashioned," and, consequently, it shares the esteem in which such subjects are held at the present time.

If left alone, after being planted in fairly good soil, it will soon grow to a bold specimen. Plants three years old are 2ft. across; rockwork or ordinary borders are alike suitable for it, but if planted on the former, it should be of a bold character, so as to harmonise. I have observed that neither grubs nor slugs seem to meddle with this plant, which is certainly a rare recommendation. Its propagation may be carried out at almost any time.

Flowering period, March to July.

Echinacea Purpurea.

_Syn._ RUDBECKIA PURPUREA; PURPLE CONE-FLOWER; _Nat. Ord._ COMPOSITÆ.

In the autumn season one is almost confined to Composites, but in this subject there is, at any rate, a change, as regards colour. Yellows are indispensable, but then predominate too strongly. The flower under notice is a peculiar purple with greenish-white shadings. This will doubtless sound undesirable, but when the flower is seen it can hardly fail to be appreciated. It is much admired; in fact it is stately, sombre, and richly beautiful--not only an "old-fashioned" flower, but an old inhabitant of English gardens, coming, as it did, from North America in the year 1699. In every way the plant is distinct; it does not produce many flowers, but they individually last for several weeks, and their metallic appearance is a fitting symbol of their durability. They begin to expand in the early part of September, and well-established plants will have bloom until cut off by frost.

The flowers are borne at the height of 2ft. to 3ft., and are produced singly on very thick, rigid stalks, long, nearly nude, grooved, furnished with numerous short, bristle-like hairs, and gradually thickening up to the involucrum of the flower. Said involucrum is composed of numerous small leaves, a distinguishing trait from its nearest relative genus _Rudbeckia_. The receptacle or main body of the flower is very bulky; the ray is fully 4in. across, the florets being short for so large a ray; they are set somewhat apart, slightly reflexed, plaited, and rolled at the edges, colour reddish-purple, paling off at the tips to a greyish-green; the disk is very large, rather flat, and furnished with spine-like scales, whence the name _Echinacea_, derived from _echinus_ (a hedgehog). In smelling this flower contact should therefore be avoided; it is rather forbidding; the disk has changeable hues of red, chocolate, and green. The leaves of the root are oval, some nearly heart-shaped, unevenly toothed, having long channelled stalks; those of the stems are lance-shaped, distinctly toothed, of stouter substance, short stalked, and, like those of the root, distinctly nerved, very rough on both sides, and during September quickly changes to a dark, dull, purple colour. The habit of the plant is rather "dumpy;" being spare of foliage, thick and straight in the stems, which are drum-stick like; it is for all that a pleasing subject when in flower; I consider the blooms too stiff for cutting, more especially as they face upwards.

Unlike many species of its order, it is somewhat fickle. I have lost many plants of it; it likes neither shade nor too much moisture; latterly I have found it to do well in a sunny situation, in deep rich loam and vegetable soil mixed. If planted with other ray flowers it forms a fine contrast, and when once it has found suitable quarters the more seldom it is disturbed the better. It may be propagated by division, which may be more safely done after growth has fairly started in spring, or it may be done at the sacrifice of the flowers in late summer or early autumn, before growth or root action has ceased.

Flowering period, September to end of October.

Edraianthus Dalmaticus.

_Nat. Ord._ CAMPANULACEÆ.

A rare and beautiful alpine species, from Dalmatia and Switzerland. At the end of July it is one of the most distinct and charming flowers in the rock garden, where it not only finds a happy home, but, by its neat and peculiar habit, proves a decorative subject of much merit. This desirable plant (see Fig. 36) is quite hardy in this climate, being herbaceous and perennial; it has, however, the reputation of being difficult to manage, but, like numerous other things, when once its requirements and enemies are found out, the former supplied and protection from the latter afforded, it proves of easy management. In some instances these conditions may, though stated in such few words, prove comprehensive; but in this case it is not so. The position and soil it most seems to enjoy may be readily afforded in any garden, as we shall shortly see; but, so far as my experience goes, the slugs are its most persistent enemies. Especially when in flower do they make long journeys to reach it; they go over sand and ashes with impunity, and often the beautiful tufts of bloom are all grazed off in one night. I had occasion to fetch in from the garden the specimen now before me, and, when brought into the gaslight, a large slug was found in the midst of the grassy foliage, and a smaller one inside one of the bell flowers. The "catch and kill 'em" process is doubtless the surest remedy, and three hours after sunset seems to be the time of their strongest muster. Not only does this plant suffer from slugs when in flower, but perhaps equally as much when in its dormant state, especially if the winter is mild; then I have noticed the somewhat prominent crowns eaten entirely off, and it is not unlikely that this plant has come to have the name of a fickle grower, from being the favourite prey of slugs.

It is not more than 4in. high under any conditions in this climate, and more often only 3in. in height. From the thrift-like tufts of foliage there radiates a set of stout round flower stalks, which are 3in. to 4in. long, and rest on the ground; the large heads of flowers are erect; the stalks are red, and furnished with short stout hairs and short foliage, the latter becoming sere long before the bloom fades. The crowded heads of "bells" are of pale purple colour, in the style of the bell-flower; they are an inch in length, the corolla being somewhat deeply divided; eight to twelve form the terminal cluster, and they have a fleshy calyx, with very long and persistent segments; the lower part can scarcely be seen for the ample and somewhat peculiar bract which closely embraces the whole cluster; said bract springs from the much thickened stalk and is composed of half leaf and half scale-like forms, arranged in two or more circles; the scales feather off with the leaf-like appendage, the latter being reflexed, but the whole is furnished with spines. The foliage of a well-grown specimen is arranged in tufts, the whole having a grass-like appearance. The leaves are 2in. to 4in. long, rough and hairy on the upper side, smooth and shining underneath, the edges having rather long hairs their whole length; the main root is long, thick, and somewhat woody.

To grow this plant well, it requires a good deep loam for its long roots, and a surfacing of grit will be of benefit, as the crowns should be clear of the damp loam. This elevation of the crowns is natural to the plant, and should be provided for. The position cannot well be too exposed, provided the deep searching roots can find plenty of moisture. On rockwork this subject may be planted with considerable effect. If put between large stones in upright positions, the plant will show its pretty form to advantage. The spoke-like flower stalks, radiating from the rich dark green tufts of foliage, are very pleasing. It may be propagated by offsets from strong and healthy plants. Care should be taken not only to have all the roots possible with each crown, but the young stock should be carefully established in pots before planting in the open. Shade and careful watering will be needful; too much of the latter will render rot inevitable. Soon as the flowering period is past is the best time to divide the roots, which should not be done too severely.

Flowering period, July and August.

Epigæa Repens.

CREEPING _or_ GROUND LAUREL; _Nat. Ord._ ERICACEÆ.

A hardy evergreen creeper, long since imported into this country from North America (1736), but only within the last few years has it won much favour. At the present time it is much sought after. It has the reputation of being a ticklish subject to grow. Many have had it and lost it, and those who still retain a specimen are loth to mutilate it for increase. This may to some extent account for the present demand for and difficulty experienced in obtaining it. For the last three years, hard as the seasons have been within that time, its flowers have been produced in great abundance on my specimen.

Usually it flowers in this climate in April, but when winter has continued open and genial, its blooms are produced as early as the middle of March, and they are in their full beauty in early April. They are white, delicately tinged with pink, of much substance and wax-like appearance. They are small, not unlike in form the lilac flower, but rather more open at the corolla and shorter in the tube. They are arranged in one-sided, elongated bunches, which rest on the ground, the blossoms peeping through the foliage. I must not omit to mention perhaps the most desirable property of this species--viz., the perfume of its flowers, which is strong, aromatic, and refreshing. The leaves are cordate, ovate, and entire, nearly 2in. long, slightly drawn or wrinkled, and covered with stiffish hairs. They are arranged on procumbent branches, all, like the flowers, facing upwards. To see the clusters of waxy flowers these branches must be raised, when it will be seen that the flower stalks issue from the axils of the leaves all along the branches. In a cut state the flowers are more than useful; they are, from their delicious, scent, a great treat. The plant is a suitable companion to the ledums, kalmias, gaultherias, and other genera of its own order.

Its culture, in this climate at least, has, from all accounts, proved rather difficult, so that it may be said to require special treatment; such, at any rate, has been my experience of it. Suitable soil, aspect, shelter, moisture, and position, all seem necessary for the well-doing of this plant. It deserves them all, and, let me add, they may all be easily afforded. The list of requirements may seem formidable on paper, but to put them into practice is but a trifling affair. My specimen is grown in leaf mould, a little loam mixed in with it, and fine charcoal instead of sand, but sand will answer nearly as well; the aspect is east, it is sheltered from the west by a wall, the north by rhododendrons, and the south by a tall andromeda. Moreover, its position is one that is sunken between small mounds, where moisture collects, and is never wanting; and when the specimen was first planted a large sandstone was placed over its roots to further secure them against drought; under these conditions it has thriven and flowered well, and afforded many offshoots. I attribute its well-doing mainly to the sheltered aspect and even state of moisture, but doubtless all the conditions have helped its growth. Its propagation is best carried out by earthing up about the collar, so as to induce the branches to become rooted, or they may be pegged near the extremities like carnation layers, but they will be two years, probably, before they can be safely lifted.

Flowering period, middle of March to end of April.

Eranthis Hyemalis.

_Syn._ HELLEBORUS HYEMALIS; WINTER ACONITE; _Nat. Ord._ RANUNCULACEÆ.

This, though well known and a general favourite, is not seen in the broad masses which ought to characterise its culture.

It is nearly related to the Christmas roses, and, like them, flowers in winter, the bright golden blossoms suddenly appearing during sunshine close to the earth. A little later the involucrum becomes developed, and is no unimportant feature. It forms a dark green setting for the sessile flower, and is beautifully cut, like the Aconite. There are other and very interesting traits about this little flower that will engage the study of botanists.

It enjoys a moist soil, somewhat light; also a little shade. In such quarters not only do the tubers increase quickly, but the seed germinates, and if such positions are allowed it, and garden tools kept off, there will soon be a dense carpet of golden flowers to brighten the wintry aspect of the open garden. Many things in the way of deciduous flowering shrubs may be grown with them, their bareness in winter and shade during summer favouring their enjoyment and growth. Early in the summer they die down. From that time the tubers may be lifted and transplanted. Such work should be finished in early autumn, or the roots will not have time to establish themselves for the first winter's bloom.

Flowering period, December to February.

Erica Carnea.

WINTER HEATH; _Nat. Ord._ ERICACEÆ.

A well-known, hardy, evergreen shrub, belonging to a genus comprising many hundreds of species and varieties, which, for the most part, however, are not hardy in this country, being natives of the Cape. The genus is most numerously and beautifully illustrated in _Loddige's Botanical Cabinet_. This might be thought to have no claim to consideration in this book, but I introduce it because of its great value in the spring garden, and because in all respects it may be cultivated like an ordinary border plant, which is saying a deal for one of the Heath family.

_Erica carnea_ comes to us from Germany, but it has so long been grown in this country that it would appear to have become naturalised in some parts. In the latter part of March it is to be seen in its full beauty; the flowers are reddish-purple, abundantly produced on short leafy stems, and arranged in racemes, drooping; the foliage is of the well-known Heath type; the whole shrub has a procumbent habit, rarely growing more than a foot high; its fine deep green foliage, compact habit, and bright enduring flowers are its chief recommendations; the latter often last six weeks in good form and colour, so that little more needs to be said in its praise.

It can hardly be planted in a wrong position--on rockwork, in borders, or shrubberies, fully exposed, or otherwise, it proves a cheerful object, whilst as an edging shrub it is second to none, excelling box by the additional charm of its flowers. Not long since I was struck by the way in which the common vinca had interlaced itself with a few bushes of this Heath, both being in full bloom at the same time; the effect was truly fine, the red of the Heath and pale blue flowers of the periwinkle being so numerous and set on such a fine bright green carpet, of two distinct types of foliage, that to my mind they suggested a most pleasing form of spring bedding, and also one of semi-wildness, which, for quiet beauty, more laboured planting could certainly not excel. Most Ericas require peaty soil; in the case of this, however, it is not necessary. Doubtless it would do well in peat, but I have ever found it to thrive in ordinary loam or garden soil, so that I have never planted it otherwise, except where peat has been the most handy. It is also easily propagated, carrying, as it does, plenty of root as well as earth with each rooted stem; these only need to be carefully divided and transplanted in showery weather, just before the new growths commence being the best time. An annual top dressing of leaf mould is very beneficial.

Flowering period, February to April.

Erigeron Caucasicus.

CAUCASION FLEABANE; _Nat. Ord._ COMPOSITÆ.

Herbaceous and perennial. This species is a somewhat recent introduction compared with some of the same genus which may be called old varieties, from having been introduced as early as 1633, as in the case of _E. graveolens_. Moreover, the genus is represented by such British species as _E. acris_, _E. alpinus_, and _E. uniflorus_. The variety now under notice is, as its specific name implies, a native of the Caucasus, first brought into this country about sixty years ago. It is a pleasing subject when in flower, and is certainly worth growing.

Its daisy-shaped flowers are less than an inch across, and when fully matured of a rosy purple colour; but, perhaps, the most interesting and attractive features about this plant are the various forms and colours of its flowers at their different stages of development; just before opening, the buds are like miniature birds' nests formed of white horsehairs, all arranged in the same way, _i.e._, round the bud, but the points are turned into the centre--these are the unexpanded florets; the next stage of development may be seen in buds, say, two days older, when a few of the florets have sprung from the nest form, and have the appearance of mauve-coloured spiders' legs laid over the bud; gradually they (being dense and numerous) expand in a similar manner, outgrowing their angularity, and at the same time deepening in colour, until at length we see the rosy-purple, daisy-shaped, and feathery flower with a yellowish centre. These pleasing flowers are borne in loose masses on stems nearly 2ft. high, and remain in bloom all the summer through.

About the middle of August a large plant was divided, and the flowers were then cut away. The young stock so propagated were in flower in the following June. I may here appropriately name an experiment I tried on this species two years ago. It was sent to me as the dwarf _Aster dumosus_, which it much resembles in the leaves, these being spoon-shaped from the roots, the others tongue-shaped and stem-clasping, but rougher and lighter green. I also saw it was not woody enough in the stem for the Michaelmas daisy. It was then near flowering, and the winter was just upon us, so, in order to get the flowers out, I covered it with a bell glass, slightly tilted. It flowered, and continued to flower throughout the winter with such shelter, and doubtless many of our fine late-blooming perennials, by such simple contrivances, might have their flowers protected or produced at a much later date than otherwise.

Flowering period, June to October.

Erigeron Glaucum.

_Syn._ CONYZA CHILENSIS; GLAUCOUS FLEABANE, _or_ SPIKENARD; _Nat. Ord._ COMPOSITÆ.

This very beautiful species is far from common. There are many facts in connection with it which render it of more than ordinary value and interest. It is sometimes classed as an alpine; probably that is only an inference, or it may be so considered by some, from its dwarf habit and suitable association with alpines. It is not an alpine; it comes from South America, and though that climate differs so widely from ours, the plant grows and winters to perfection in this country.

One of its main distinctions is its somewhat shrubby and evergreen character; of the whole genus, so far as it is at present comprehended, it is the only species with such traits; its foliage, too, is of leathery substance, and compares oddly with the herb-like leaves of its relatives; it is, moreover, as indicated by its specific name, of a glaucous hue; and otherwise, as may be seen in the following description, there exist well marked dissimilarities. But, what is of more importance, when viewed as a garden subject or an ornamental flower, it is one of the most useful as well as distinctly beautiful, as much from the fact that it produces its flowers in two crops, which extend over six or seven months of the year, as from their numbers and showiness.

The flowers are nearly 2in. across the ray, the florets being of a pleasing lilac-purple, and rather short, owing to the large size of the disk, which is often nearly an inch in diameter; this part of the flower is more than usually effective, as the disk florets become well developed in succession, when they have the appearance of being dusted with gold; the scales, which are set on the swollen stem, are of a substantial character; the numerous imbricate parts, which are covered with long downy hairs pointing downwards, give the body of the flower a somewhat bulky appearance. It will be observed that I have made no mention of the Conyza traits of divided ray florets and reflexed scales, simply because they do not exist in this species, and though there are other Conyza traits about the plant, notwithstanding its almost isolating distinctions from other Erigerons, it would seem to have more properly the latter name, and which is most often applied to it. The flower stems, which produce the flowers singly, seldom exceed a height of 12in.; they are stout, round, and covered with soft hairs, somewhat bent downwards. They spring from the parts having new foliage, and for a portion--about half--of their length are furnished with small leaves, which differ from those on the non-floriferous parts of the shrub, inasmuch as they have no stalks. The leaves are produced in compact tufts on the extremities of the old or woody parts of the shrub, which become procumbent in aged specimens; the leaves vary in length from 2in. to 4in. long, and are roundly spoon-shaped, also slightly and distantly toothed, but only on the upper half; they are stout, ribbed, clammy, and glaucous. The habit of the shrub is much branching, dense, and prostrate; its foliage has a pleasant, mentha-like odour, and the flowers have a honey smell.

This subject may occupy such positions as rockwork, borders of the shrubbery, or beds of "old-fashioned" flowers. Its flowers, being, as taste goes at the present time, of a desirable form, will prove very serviceable as cut bloom. A good loam suits it to perfection, and no flower will better repay a good mulching of rotten manure. Its propagation, though easy, is somewhat special, inasmuch as its woody parts are stick-like and bare of roots, until followed down to a considerable depth, therefore the better plan is either to take advantage of its prostrate habit by pegging and embedding its branches, or, as I have mostly done, take cuttings with a part of the previous season's wood to them, put them well down in deeply-dug light soil, and make them firm. If this plan is followed, it should be done during the summer, so that the cuttings will have time to root before winter sets in. The layering may be done any time, but if in spring or summer, rooted plants will be ready for the following season.

This subject begins to flower in June, and, as already hinted, it produces two crops of flowers; the first are from the parts which have been green and leafy through the winter, the second from the more numerous growths of the new season, and which are grandly in bloom in August; not only are the latter more effective as regards numbers and colour, but the fuller habit or more luxuriant condition of the shrub render the specimens more effective in late summer.

Eryngium Giganteum.

GREAT ERYNGO; _Nat. Ord._ UMBELLIFERÆ.

This hardy species was brought from the Caucasus in 1820. The genus, though not commonly patronised as garden subjects, are, nevertheless, highly ornamental, and when well grown much admired. Specimens are of various heights, according to position and nature of the soil; under ordinary conditions they will be 2ft. to 3ft. high at the blooming period.
