Chapter D: WINTERI (syn Winter a aromatica).--Winter's Bark. South America,

1827. The fine evergreen character is the chief attraction of this American shrub, so far at least as garden ornamentation is concerned. With some persons even the greenish-white flowers are held in esteem, and it cannot be denied that a well flowered plant has its own attractions. The long, narrow leaves are pale green above and glaucous beneath, and make the shrub of interest, both on account of their evergreen nature and brightness of tint. Unfortunately it is not very hardy, requiring even in southern England a sunny wall to do it justice.

ELAEAGNUS.

ELAEAGNUS ARGENTEA.--Silver Berry. North America, 1813. A spreading shrub 8 feet or 10 feet high, with lanceolate leaves clothed with silvery scales. The flowers are axillary and clustered, and are succeeded by pretty, silvery-ribbed berries.

E. GLABRA (_syn E. reflexus_).--From Japan. This is one of the handsomest species, forming bushes of delightful green, leathery leaves, and with a neat and rather compact habit of growth. It grows with great freedom when planted in light, sandy soil, big globose bushes being the result of a few years' growth. Being perfectly hardy it is to be recommended if only for the ample leathery, deep green foliage. The flowers are inconspicuous. There is a form having the leaves margined with pale yellow, and known under the name of E. glabra variegata.

E. LONGIPES (_syn E. edulis_ and _E. crisp a_).--Japan, 1873. This species, is also worthy of culture, whether for the ornamental flowers or fruit. It is a shrub 6 feet high, bearing an abundance of spotted, oval red berries on long footstalks. Quite hardy.

E. MACROPHYLLA.--Japan. This is of robust growth, with handsome, dark green leaves, and purplish branch tips. The leaves are thick of texture, often fully 3 inches long, glossy-green above, and silvery beneath. The latter is all the more remarkable, as the leaves have the habit of curling up their edges, and thus revealing the light, silvery tint of the under sides. It thrives well in light, sandy peat, and may be relied upon as one of the hardiest of shrubs.

E. ROTUNDIFOLIA.--An interesting and perfectly hardy species, growing about five feet high, and remarkable for the great wealth of pretty scarlet and amber-coloured berries. The flowers are not very showy, but this is made up by the beautiful silvery leaves, most pronounced on the under sides, and wealth of fruit, which hangs on long stalks like Cherries.

Other species of less interest are E. pungens, of which there is a variegated variety; E. Simoni, a neat Chinese shrub; and E. latifolia, of good habit and with large leaves. The various species and varieties of Elaeagnus may all be cultivated in light, free soil, and from experiments that were recently made, they have been found of great value for planting by the seaside. They are popularly known as the Wild Olives and Evergreen Oleasters.

EMBOTHRIUM.

EMBOTHRIUM COCCINEUM.--Fire Bush. South America, 1851. This is a beautiful shrub, of tall growth, with flowers of great interest and beauty. Except in warm and favoured situations, it is not very hardy, and should always be grown as a wall plant. The fiery scarlet, orange-tinted flowers, resembling somewhat those of the Honeysuckle, are very beautiful by the first weeks of May. It grows to about 6 feet in height in southern England, and is, when in full flower, a shrub of unusual beauty.

EPHEDRA.

EPHEDRA VULGARIS (_syn Ephedra monastachya_), from Siberia, 1772, is a half-hardy shrub of trailing habit, with inconspicuous flowers. Thriving in very poor soil, or on rocky situations, is the only reason why it is introduced here.

EPIGAEA.

EPIGAEA REPENS.--Ground Laurel, or New England Mayflower. Northern United States, 1736. This is, perhaps, in so far as stature is concerned, hardly worthy of a place in our list, yet it is such a pretty and useful shrub, though rarely rising more than 6 inches from the ground, that we cannot well pass it over. For planting beneath Pine or other trees, where it can spread about at will, this prostrate shrub is most at home. There it enlivens the spot with its pretty evergreen foliage, and sweet-scented, white or pinky flowers. It is quite hardy.

ERCILLA.

ERCILLA SPICATA (_syn Bridgesia spicata_).--Chili, 1840. A small-growing, half-climbing shrub, with leathery, deep green leaves, and inconspicuous flowers. Hailing from Chili, it is not very hardy, but given the protection of a wall, or planted against a tree-stump, it soon forms a neat mass of evergreen foliage.

ERICA.

ERICA CARNEA.--South Europe, 1763. This is one of the most beautiful and desirable of hardy Heaths, on account of the richly-coloured flowers and early season at which they are produced. In the typical species the flowers are pink or flesh-coloured, and produced in January and February. It is a dwarf, compact growing species, with bright green foliage. There is a form with pure white flowers, named E. carnea alba, or E. herbacea, but although distinct and beautiful, it is not of so robust growth as the parent.

E. CILIARIS.--A pretty native species, with ciliate glandular leaves, and racemes of highly-coloured, rosy flowers. Found in Dorsetshire and Cornwall.

E. CINEREA,--Gray-leaved Heath. In this species, also a native of Britain, the flowers are of a reddish-purple colour, and borne in dense terminal racemes. There are numerous varieties, including a white-flowered E. cinerea alba; E. cinerea atro-purpurea, bearing dark purple flowers; E. cinerea atro-sanguinea, dark red flowers; E. cinerea coccinea, scarlet; E. cinerea purpurea, purple flowers; and E. cinerea rosea, with deep rose-coloured flowers.

E. MEDITERRANEA.--Mediterranean Heath. Portugal, 1648. This is a robust-growing species, of rather erect habit, and often attaining to fully a yard in height. Flowers abundantly produced, and of a pretty pinky hue. Of this there are several varieties, the following being best known: E. mediterranea hibernica, found in Ireland; E. mediterranea alba, with white flowers; E. mediterranea nana, of very dwarf growth; and E. mediterranea rubra, with showy, deep red flowers.

E. SCOPARIA and E. ERECTA are desirable species, the former bearing greenish flowers, and the latter of decidedly upright growth.

E. TETRALIX.--Cross-leaved Heath. A native species of low, and bushy growth, with close umbels or terminal clusters of pretty pinky flowers. The varieties of this most worthy of notice are E. Tetralix alba, white flowered; E. Tetralix Mackiana, crimson flowered; E. Tetralix rubra, deep red flowers; and E. Tetralixbicolor, with parti-coloured flowers.

E. VAGANS..--Cornish Heath. A native species, bearing pinky-white flowers, but there are forms with white and red flowers, named E. vagans alba and E. vagans rubra.

The various kinds of Heath succeed best either in peaty soil, or that composed for the greater part of light, sandy loam, but many will grow and flower freely if planted in rich yellow loam. They are very desirable plants, either for bed formation, for rockwork ornamentation, or for planting around the shrubbery margins. Propagation is effected either by cuttings or sub-divisions, but seedlings of several species spring up freely under favourable conditions.

ESCALLONIA.

ESCALLONIA FLORIBUNDA (_syn E. montevideusis_).--New Grenada, 1827. This is one of the handsomest species, bearing long, arching clusters of white flowers. It is a very desirable shrub for wall or lattice-work covering, against which it grows rapidly, and soon forms an object of great beauty by reason of its neat foliage and graceful habit, as also wealth of pretty flowers.

E. ILLINATA.--Chili, 1830. This should also be included, it being a handsome and pretty-flowered plant.

E. MACRANTHA.--Chiloe, 1848. This is a general favourite in English gardens, where it succeeds well, but especially in maritime parts of the country. It is of stout growth, 6 feet or more in height, of spreading habit, and with elliptical, serrulated, bright green leaves, and clusters of crimson-red flowers produced in summer. For wall-covering this is an almost invaluable shrub, although it succeeds well as a standard in all but the colder parts of the country. Any free, open soil suits it well, but thorough drainage must be attended to. There are several very distinct and good varieties, such as E. macrantha sanguinea, with flowers deeper in colour than those of the parent plant; and E. macrantha Ingrami, a profuse-blooming and very desirable form.

E. PHILLIPIANA.--Valdivia, 1873. When seen as a standard bush, and loaded with its myriads of tiny white flowers, this must rank amongst the handsomest members of the family. It is very hardy, and retains its foliage throughout the winter. The hybrid forms, E. exoniensis and E. leucantha, deserve recognition, the latter even as late as November being laden with its small spikes of pretty white flowers, which contrast nicely with the neat, evergreen foliage.

E. PTEROCLADON.--Patagonia, 1854. This is remarkable for the curiously-winged branches, which give to the shrub a rather peculiar and distinct appearance. The freely-produced flowers are white or pink.

E. RUBRA.--Chili, 1827. This has less handsome leaves and flowers than the above, but it is, all the same, a beautiful plant. The flowers vary a good deal in depth of colouring, and may be seen of all tints between pure white and red.

The Escallonias are all of very free growth in any light, warm, sandy, and well-drained soil, and are readily propagated.

EUCRYPHIA.

EUCRYPHIA PINNATIFOLIA.--Chili, 1880. This shrub, is as yet rare in cultivation, and is not suited for the colder or more exposed parts of the country. It is, however, a singularly distinct and beautiful shrub, with deep glossy-green, pinnate foliage, and bearing large, pure white flowers, that are rendered all the more conspicuous by the golden-yellow anthers. As an ornamental shrub it is well worthy of cultivation. In so far as its hardihood in this climate has to do, it may be mentioned that in various parts of England and Ireland it has stood in the open ground unharmed for several years back. Light, sandy, well drained peat would seem to meet with its requirements.

EUONYMUS.

EUONYMUS AMERICANA.--American Spindle Tree. North America, 1686. This is a deciduous or semi-evergreen shrub, of about 6 feet in height, found over a wide area in Canada and the United States. It is of partially erect growth, with long and lithe branches, covered with pleasing light green bark. Flowers appearing in June, and succeeded by rough, warted, brilliant scarlet capsules, which are particularly showy and attractive. It likes a shady situation, and rich, rather damp soil.

E. EUROPAEUS.--West Asia, Europe (Britain), &c. An indigenous species, rarely exceeding 6 feet in height, and rendered very effective in autumn by reason of the pale scarlet fruit, which, when fully ripe, and having split open, reveals the orange-coloured arils of the seeds. It, too, delights to grow in the shade.

E. FIMBRIATUS, Japan and India, and its handsome variegated form, E. fimbriatus foliis variegatus et argenteo maculatus, are rather too tender for cultivation in this country, even in southern districts, and where afforded wall protection. E. verrucosus and E. atropurpureus are also worthy of cultivation.

E. LATIFOLIUS.--Broad-leaved Spindle Tree. A European species (1730), deciduous, and growing from 10 feet to sometimes fully 20 feet in height. The leaves are bright, shining green, and much larger than those of our native species. Flowers, purplish-white, appearing in June; the capsules large, deep red, and when open contrasting very effectively with the bright orange arils in which the seeds are enveloped. It is a very distinct and beautiful, small-growing lawn tree, and succeeding, as it does, best in shade is an extra qualification.

FABIANA.

FABIANA IMBRICATA.--Chili, 1838. This is, unfortunately, not hardy in any but the milder maritime parts of England and Ireland. It is a charming shrub of Heather-like appearance, with small, crowded leaves, and pure white flowers produced in May. Planted at the base of a southern wall it does best, and where it thrives it is certainly one of our handsomest half-hardy shrubs.

FATSIA.

FATSIA JAPONICA (_syns Aralia japonica_ and _A. Sieboldii_).--Japan, 1858. This is of no particular value as a flowering shrub, but being hardy in most districts, and having large handsome leaves that impart to it a tropical appearance, it is well worthy of culture. The flowers are ivory-white, and produced in large umbels towards the end of autumn, but our early frosts too often mar their beauty. In this country it grows about 10 feet high, and is usually what is termed "leggy" in appearance, and thrives well in any good loamy soil if fairly dry.

FENDLERA.

FENDLERA RUPICOLA.--Mexico, 1888. A low-growing shrub, peculiar to the dry rocky parts of the United States, particularly the south-western district. It grows about a yard high, and bears a great profusion of bluish-white flowers, that are rendered very conspicuous by reason of the bright yellow stamens. It is the only known species, and is nearly allied to the Saxifrages. Any fairly good garden soil will suit it well, but it wants to be planted where superfluous moisture is quickly carried off.

FORSYTHIA.

FORSYTHIA SUSPENSA (_syn F. Fortunei_ and _F. Sieboldii_).--Japan and China, 1864. A slender-growing shrub, with variable leaves, and long, trailing shoots. The flowers are abundantly produced, are of a beautiful golden tint, and bell-shaped, and being of good substance last for a long time. Either as a wall plant, or for using in some sheltered corner, and where the branches can spread about at will, it forms a very distinct and handsome shrub, and one that is perfectly hardy and quite indifferent as regards the quality of soil in which it is planted. There are several forms of this pretty shrub, but as they do not differ to any great extent from the species, are hardly worthy of consideration.

F. suspensa intermedia is a garden hybrid, 1891.

F. VIRIDISSIMA.--Japan, 1845. This is another desirable species, but it is not comparable in point of beauty with the former. It is usually of strong erect growth, with stout shoots, wreathed with bright yellow flowers towards the end of winter. It is a very beautiful shrub, and a valuable addition to the winter or early spring flowering section.

FOTHERGILLA.

FOTHERGILLA ALNIFOLIA.--North Eastern America, 1765. This is an ungainly habited shrub, of dwarf growth, the branches being somewhat slender and crooked. The flowers are white, sweetly scented, and produced in dense terminal spikes. It is perfectly hardy.

FRAXINUS.

FRAXINUS ORNUS (_syn F. argentea, F. rotundifolia_, and _Ornus europea_).--Manna Ash. South Europe, 1730. This is a handsome tree, especially when young and vigorous, and by far the most ornamental species in cultivation. For planting in situations where large-growing subjects would be out of place this is a valuable tree, while the wealth of flowers renders it particularly interesting and effective. It rarely exceeds 30 feet in height, with leaves not unlike those of the common Ash, and conspicuous panicles of light, feathery, white petaliferous flowers, produced usually in great abundance all over the tree. Perfectly hardy.

F. Ornus serotina alba and F. Ornus serotina violacea are beautiful seedling forms that were raised in France, and on account of their dwarf habit and profusion of flowers are well worthy of attention. The flowers of the first-named variety are pure white, the stamens having at first yellow anthers, which speedily turn to a rich blackish-brown. The other differs but little, only in the flowers, which are of a distinct greyish-violet hue, while the leaves are of a darker shade of green, and the leaflets longer and narrower.

F. MARIESII.--Northern China, 1880. This is hardy in most parts of the country. The whole tree is quite glabrous except the petioles, which are clothed with a dense pubescence. Flowers pure white, and arranged in large dense panicles.

FREMONTIA.

FREMONTIA CALIFORNICA.--California, 1851. A handsome and deciduous Californian shrub, but scarcely hardy enough for the open air without protection. In Southern England and Ireland, however, it does well, and all the better if planted within the influence of the sea. The large yellow flowers are often about 2 inches across, and produced singly along the branches, while the leaves are large, lobed, and of an enticing shade of green. Planted against a wall, in good dampish loam, it succeeds well.

FUCHSIA.

FUCHSIA MACROSTEMA GLOBOSA (_syn F. globosa_).--Chili. This is readily recognised by the globose form assumed by the incurved sepals, while the flowers are smaller and less showy than those of F. Riccartoni. Hardihood about similar to the following.

F. RICCARTONI.--This seedling from F. m. globosa is one of the two hardiest varieties, but even this plant, except in warm, maritime districts, is by no means satisfactory. Where it does well it is a shrub of great beauty, and blooms profusely. This species has red, straight sepals, and a purple corolla. In favoured districts it may frequently be seen as much as 12 feet high, and is then during the flowering period an object of great beauty. It originated at Riccarton, near Edinburgh, about 1830.

GARRYA.

GARRYA ELLIPTICA.--California, 1818. This is a handsome shrub, with dark green coreaceous leaves, resembling very nearly those of the Evergreen Oak. The long, tassellated catkins, of a peculiar yellowish-green colour, render the plant one of much interest and beauty. As a wall plant it thrives well, the slight protection thus afforded favouring the growth and expansion of the catkins. For planting in the shrubbery it is also well suited, and where it oft-times attains to a height of 6 feet, and is bushy in proportion. It is well to bear in mind that there are male and female plants of the Garrya, and that the former is the more ornamental. Good rich, well-drained loam will suit this shrub well.

GAULTHERIA.

GAULTHERIA NUMMULARIOIDES (_syn G. nummulariae_ and _G. repens_). --Himalayas. This is a neat Alpine species, with small and very dark green leaves. It likes a shady situation and vegetable soil. For planting on the rockwork, amongst tree roots, or beneath the shade of trees, the Gaultherias are particularly suitable. Light, but rich vegetable soil suits them best.

G. PROCUMBENS.--Canada Tea, or Creeping Winter-green. North America, 1762. This is of much smaller growth than the following, rarely rising to a greater height than about half a foot, with lanceolate, serrated leaves, and pendulous axillary clusters of white flowers.

G. SHALLON.--North-west America, 1826. Growing in favourable situations to fully a yard in height, this distinct evergreen shrub, which is fairly common in cultivation, is particularly valuable, as it thrives well under the shade and drip of trees. It is a rambling plant, with ovate-cordate, almost sessile leaves, and bears tiny white flowers that are succeeded by purplish fruit. G. Shallon acutifolia has more sharply pointed leaves than those of the species.

GENISTA.

GENISTA AETNENSIS (_syn Spartium aetnensis_).--Etna Broom. Sicily and Sardinia, 1816. This is a large-growing species of elegant growth, and remarkable for the abundance of yellow flowers with which it is literally covered in August. Than this South-European Pea-flower, perhaps not another member of the family is more worthy of culture, the neat, elegant habit of growth and profusion of flowers rendering it a plant of particular interest and beauty. It is quite hardy, thrives in any light soil if well drained, and is readily propagated from seed, which it ripens in abundance.

G. ANXANTICA.--Naples, 1818. This is a nearly allied species to our native G. tinctoria, and is of dwarf growth with a rich abundance of golden yellow flowers that are produced towards the end of summer.

G. CINEREA (_syn G. ramosissima_), from South Europe, is a very beautiful and desirable species, a yard high, and bearing in July slender twigs of the brightest yellow flowers.

G. EPHEDROIDES.--Corsica and Sardinia, 1832. With small and abundantly-produced flowers, this resembles Ephedra, hence its name.

G. GERMANICA.--Germany, 1773. This is a handsome rock garden shrub, of fully 18 inches in height, with arching stems and a plentiful supply of bright flowers during the summer and autumn months.

G. HISPANICA.--South-western Europe, 1759. This species resembles our common Broom, but the branches are not angular. The large, yellow, fragrant flowers appear in July. There is a charming double-flowered variety named G. hispanica flore-pleno.

G. LUSITANICA.--Portugal, 1771. This is remarkable for its opposite branches, is of spiny growth, and one of the earliest to appear in flower.

G. MONOSPERMA.--South Europe, 1690. This has white flowers, and is of value as a seaside shrub, and grows well in almost pure sand. A native of the Mediterranean coast.

G. PILOSA.--Greenweed. Europe (Britain). This is a dense prostrate native species, with bright yellow blossoms produced freely during May and June. A delightful rock shrub, and one that will succeed well almost in pure gravel.

G. PROSTRATA.--Burgundy and Alps of Jura, 1775. A small-growing species suitable for rock gardening, and of spreading bushy growth. Flowers small, but ornamental, and produced in May and June.

G. RADIATA (_syn Spartium radiatum_).--South Europe, 1758. This is a slender-growing shrub, about 18 inches high, with narrow leaflets, and terminal heads of yellow flowers produced in summer.

G. SAGITTALIS.--South Europe, 1750. With its peculiarly winged and jointed stems, which are of a deep green colour, this is one of the most distinct forms. The flowers are few but pretty, and with the dwarf habit render the plant an excellent subject for rockwork.

G. TINCTORIA.--Dyers' Greenweed. Europe (Britain), North and West Asia. This is a spineless species, and bears a profusion of yellow flowers from July onwards. The double-flowering variety, G. tinctoria flore-pleno, is, in so far as ornamental qualities are concerned, superior to the parent form.

G. TINCTORIA ELATIOR (_syn G. elatior_) grows to 12 feet in height, is of free, spreading growth, and a very handsome plant. The flowers, which are individually small and yellow, are so thickly produced that the shrub, in late summer, has the appearance of a sheet of gold.

G. TRIANGULARIS (_syn G. triquetra_).--South Europe, 1815. This is a decidedly good garden plant, and of neat, trailing habit. The stems are three sided, and the flowers golden yellow and plentifully produced. A native of South Europe, and perfectly hardy in almost any position.

The above include most of the hardy Genistas, though G. capitata and G. daurica, both very ornamental kinds, might be added to the list. They are all very hardy, free-flowering shrubs, of simple culture, and succeeding well in any light and rather dry soil.

GLEDITSCHIA.

GLEDITSCHIA TRIACANTHOS.--Honey Locust. United States, 1700. As an ornamental hardy tree this is well worthy the attention of planters, the pinnate and bipinnate foliage being particularly elegant, while the flowers, though individually small, are borne in such quantities of fascicled racemes as to attract notice. The stem and branches are armed with formidable prickles, but there is a form in which the prickles are absent. A native of North America, and readily cultivated in any soil of even fair quality. For town planting it is a valuable tree. There is a good weeping variety named G. triacanthos pendula.

G. SINENSIS (_syn G. horrida_).--China, 1774. This nearly resembles the latter, and is occasionally to be met with in cultivation in this country.

GORDONIA.

GORDONIA LASIANTHUS.--Loblolly Bay. North America, 1739. A shrub of great beauty, but one that, unfortunately, is rarely to be seen outside the walls of a botanic garden. It is of Camellia-like growth, with large, sweetly fragrant flowers and a good habit of growth.

G. PUBESCENS.--North America, 1774. This is of smaller growth than the latter, rarely exceeding about 6 feet high, with large white flowers that are rendered all the more conspicuous by the tuft of golden stamens. Both species are somewhat tender, although hailing from the coast, swampy grounds of the southern States of North America. Planted in favoured sites, they usually grow freely in light, peaty soil, or that containing a large admixture of decayed leaf soil.

GRABOWSKIA.

GRABOWSKIA BOERHAAVIAEFOLIA.--Peru, 1780. This is occasionally to be seen in sheltered and favoured gardens, but it is not to be relied upon in other than southern and seaside districts. The plant is of no particular interest to the cultivator, the outline being ungainly, while the pale blue flowers are both dull and uninteresting. It belongs to the Solanum family, and is only worth cultivating as a curiosity. Light, warm soil and a sunny position are necessities in the cultivation of this shrub.

GRISELINIA.

GRISELINIA LITTORALIS.--New Zealand, 1872. This forms a compact bush of moderate size, and is fairly hardy. The leaves are of a light, pleasing green shade, coriaceous, and glossy, and remain on the plant during winter. It is an excellent shrub for the seaside, and, moreover, will succeed well in stiff soils where many other plants would refuse to grow.

GYMNOCLADUS.

GYMNOCLADUS CANADENSIS.--Kentucky Coffee Tree. Canada, 1748. When in full leafage this is a distinct and beautiful tree, the foliage hanging in well-rounded masses, and presenting a pretty effect by reason of the loose and tufted appearance of the masses of finely-divided leaves. Leaves often 3 feet long, bipinnate, and composed of numerous bluish-green leaflets. Flowers white, borne in loose spikes in the beginning of summer, and succeeded by flat, somewhat curved brown pods. It prefers a rich, strong soil or alluvial deposit.

G. CHINENSIS.--Soap Tree. China, 1889. Readily distinguished from the American species by its much smaller and more numerous leaflets, and thicker fruit pod. It is not very hardy in this country unless in the milder sea-side districts. The leaves are used by the Chinese women to wash their hair, hence the popular name of Soap Tree.

HALESIA.

HALESIA DIPTERA (_syn H. reticulata_).--North America, 1758. This is not so suitable for our climate as H. tetraptera, though in southern parts of the country it forms a neat, healthy bush, and flowers freely. It is distinguished, as the name indicates, by having two wings to the seed vessel, H. tetraptera having four.

H. HISPIDA (_syn Pterostyrax hispidum_).--Japan, 1875. This is a shrub of perfect hardihood, free growth, and very floriferous. The flowers, which are pure white, and in long racemes, resemble much those of the Snowdrop Tree. Leaves broad and slightly dentated. It is a handsome shrub, of free growth, in light, sandy loam, and quite hardy even when fully exposed.

H. PARVIFLORA has smaller flowers than those of our commonly-cultivated plant.

H. TETRAPTERA.--Snowdrop Tree. North America, 1756. This is a very ornamental tall-growing shrub, of somewhat loose growth, and bearing flowers which resemble, both in size and appearance, those of our common Snowdrop. It is one of the most ornamental of all the small-growing American trees, and richly deserves a place in every collection, on account of the profusion with which the flowers are produced in April and May. They are snow-white, drooping, and produced in lateral fascicles of eight or ten together. It is a native of river banks in North Carolina, and is well suited for cultivation in this country. Light, peaty soil will grow it to perfection.

HALIMODENDRON.

HALIMODENDRON ARGENTEUM (_syn Robinia Halimodendron_).--Salt tree. A native of Asiatic Russia (1779), having silvery foliage, and pink or purplish-pink flowers, axillary or fascicled. It is a neat and pretty shrub, that is rendered valuable as succeeding well in maritime districts. Quite hardy and of free growth in sandy soil.

HAMAMELIS.

HAMAMELIS JAPONICA.--The Japanese Witch Hazel. Japan, 1862. This is a small species with lemon-yellow flowers. H. japonica arborea is a taller growing variety, with primrose-yellow petals, and a deep claret calyx. The flowers are borne in clusters in early spring. Rarely in this country do we find this species of greater height than about 8 feet, but it is of bushy growth, though somewhat straggling in appearance. As early as the beginning of January this Witch Hazel may be found in bloom, the bare branches being studded here and there with the curious-shaped flowers, these having bright yellow, twisted petals and reddish calyces. H.j. Zuccarinianais a very desirable free-flowering variety, with pale yellow petals and a greenish-brown calyx.

H. VIRGINICA.--Virginian Witch Hazel. North America, 1736. This has smaller flowers than H.j. arborea, and they are plentifully produced in autumn or early winter. In this country it assumes the shape of an open bush of about 6 feet in height, but is usually of untidy appearance from the branches being irregularly disposed.

They all delight in cool, rather moist soil, and are of value for their early-flowering nature.

HEDYSARUM.

HEDYSARUM MULTIJUGUM.--South Mongolia. Hardly ten years have elapsed since this pretty shrub was introduced into England, so that at present it is rather rare in our gardens. It is a decided acquisition, if only for the production of flowers at a time when these are scarce. Usually the flowering time is in August, but frequently in the first weeks of October the pretty flowers are still full of beauty. It is of bushy habit, from 4 feet to 5 feet high, with oblong leaflets, in number from twenty to thirty-five, which are Pea-green above and downy on the under sides. Flowers bright red, and produced in axillary racemes. It is perfectly hardy, and grows freely in porous decomposed leaf-soil.

HELIANTHEMUM.

HELIANTHEMUM HALIMIFOLIUM.--Spain, 1656. This species is of erect habit, 3 feet or 4 feet high, and with leaves reminding one of those of the Sea Purslane. It is an evergreen, and has large bright yellow flowers, slightly spotted at the base of the petals.

H. LAEVIPES (_syn Cistus laevipes_).--South-western Europe. A dwarf shrub, with Heath-like leaves, and yellow flowers that are produced in great abundance.

H. LASIANTHUM (_syns H. formosum_ and _Cistus formosus_).--Spain and Portugal, 1780. This is a beautiful species, but not hardy unless in the South and West. It has large, bright yellow flowers, with a deep reddish-purple blotch at the base of each petal.

H. LAVENDULAEFOLIUM has lavender-like leaves, with the under surface hoary, and yellow flowers. A native of the Mediterranean regions.

H. LIBONATES.--This species bears dark green Rosemary-like leaves, and yellow flowers that are produced very abundantly. South Europe.

H. PILOSUM.--South of France, 1831. This bears white flowers that are of good substance, and about an inch across.

H. POLIFOLIUM (_syn H. pulverulentum_).--Europe (Britain), and North Africa. This is a neat-growing shrub, of very dwarf growth, with hairy leaves and yellow flowers; and H. polifolium roseum, has pretty rosy-red flowers.

H. UMBELLATUM.--South Europe, 1731. A neat, small-growing species, with white flowers and glossy-green leaves covered with a rusty-white tomentum beneath.

H. VULGARE.--Common Rock Rose. Europe (Britain), North Africa, and West Asia. A widely distributed native plant, of dwarf growth, with linear-oblong, hairy leaves, and usually yellow flowers. H. vulgare nummularium differs in having the leaves green and sub-orbicular, with yellow flowers. H. vulgare barbaturn is of erect habit, with silky, hairy, oval leaves. H. vulgare mutabile bears pale rose flowers, marked with yellow at the base. H. vulgare grandiflorum is remarkable for the large, bright yellow flowers, and is one of the most beautiful and worthy varieties. H. vulgare ovalifolium (_syn H. serpyllifolium_) bears yellow flowers and ovate leaves, with the margins revolute. H. vulgare hyssopifolium bears reddish flowers, but the colouring varies considerably, and saffron is not uncommon.

The Rockroses are very valuable plants, in that they will succeed on poor, gravelly banks where few other plants could eke out an existence. They cannot withstand stiff soil, nor that at all inclined to be damp, their favourite resorts being exposed, rocky ground, and dry, gravelly banks. Being readily increased from cuttings, which take root well under a hand glass or in a cool house, it is advisable, at least with the more tender forms, to have at hand a stock, so that blanks in the shrubbery may be filled up.

HIBISCUS.

HIBISCUS SYRIACUS (_syn Althaea frutex_).--Syrian Mallow. Syria, 1596. An old occupant of our gardens, and one that cannot be too freely cultivated. When favourably situated, it often reaches 6 feet in height, with three-lobed, neatly-toothed leaves, and with large, showy blossoms that are borne towards the end of summer. The typical species has purplish flowers, with a crimson spot at the base of each petal, but others, varying in colour from snow-white to purple and blue, are common in cultivation. H. syriacus coelestis bears bright blue flowers, while H. syriacus variegatus has beautifully variegated foliage. Of the double-flowered forms, there are several beautiful and worthy plants, the following list containing some of the best varieties of this popular shrub:--

HIPPOPHAE.

HIPPOPHAE RHAMNOIDES.--Sea Buckthorn, or Sallow Thorn. Though generally considered as a sea-side shrub, the Sea Buckthorn is by no means exclusively so, thriving well, and attaining to large dimensions, in many inland situations. The flowers are not at all conspicuous, but this is amply compensated for by the beautiful silvery-like leaves and wealth of fruit borne by the shrub. In not a few instances, for fully a foot in length, the branches are smothered with crowded clusters of bright orange berries, and which render the shrub during November and December both distinct and effective. It does best in sandy soil, and is readily increased from suckers, which are usually plentifully produced by old plants. For sea-side planting it is one of our most valuable shrubs, succeeding, as it does, well down even to high water mark, and where the foliage is lashed with the salt spray.

HOLBOELLIA.

HOLBOELLIA LATIFOLIA (_syn Stauntonia latifolia_).--Himalayas, 1840. An evergreen climbing shrub that is more often found under glass than out of doors. In the South of England, however, it is quite hardy against a sunny wall. It grows 12 feet high, with shining green leathery leaves, and fragrant purplish-green flowers. H. latifolia angustifolia has decidedly narrower leaves than the species, but is in no other way different.

HYDRANGEA.

HYDRANGEA ARBORESCENS.--North America, 1736. This is a plant of large growth, but the flowers are greenish-white, and by no means conspicuous.

H. HORTENSIS (_syn Hortensia opuloides_).--China, 1790. This is an old-fashioned garden shrub that is only hardy in the south and west of these islands and in the vicinity of the sea. In some of the forms nearly all the flowers are sterile, the calyx-lobes being greatly expanded, and in others the outer flowers only are sterile. According to the nature of the soil the flowers vary much in colour, some being pure white, others pink, and others of varying shades of blue. There are some very beautiful and distinct varieties, such as H. hortensis japonica; H. hortensis Otaksa, with large panicles of sterile blue flowers; H. hortensis rosea-alba, with large rosy flowers; H. hortensis Thomas Hogg, a very free-flowering and welcome form; H. hortensis mandschurica, and H. hortensis stellata flore-pleno, with partially double flowers, are worthy of attention.

H. PANICULATA.--Japan, 1874. This is one of the most distinct species, in which the flower-heads are elongated, not flat, as in most other species, and from which the finest form in cultivation has been obtained. This is H. paniculata grandiflora, in which the flowers are sterile and pure white, forming large panicles often a foot in length. It is a magnificent variety, and, being perfectly hardy, should be extensively planted for ornament. The flowers are produced in late summer, but remain in good form for fully two months, dying off a rich reddish hue.

H. QUERCIFOLIA.--Oak-leaved Hydrangea. Florida, 1803. This species has neatly lobed leaves, and terminal panicles of pinky-white, but partially barren, flowers.

H. SCANDENS.--Climbing Hydrangea. Japan, 1879. This is not very hardy, but with the protection of a sunny wall it grows freely.

The Hydrangeas require a rich, loamy soil, and, unless in maritime districts, a warm and sheltered situation. They are readily propagated by means of cuttings.

HYMENANTHERA.

HYMENANTHERA CRASSIFOLIA.--A curious New Zealand shrub with rigid ashy-coloured branches, and small leathery leaves. The flowers are violet-like in colour, but by no means conspicuous. The small white berries which succeed the flowers are, in autumn, particularly attractive, and very ornamental. It is perfectly hardy and of free growth in light peaty earth.

HYPERICUM.

HYPERICUM ANDROSAEMUM.--Tutsan, or Sweet Amber. Europe (Britain). A pretty native species, growing about 2 feet high, with ovate leaves having glandular dots and terminal clustered cymes of yellow flowers.

H. AUREUM.--South Carolina and Georgia, 1882. This soon forms a neat and handsome plant. The flowers are unusually large, and remarkable for the tufts of golden-yellow stamens with which they are furnished.

H. CALYCINUM.--Aaron's Beard, or Rose of Sharon. South-east Europe. This is a well-known native species of shrubby growth, bearing large yellow flowers from 3 inches to 4 inches in diameter. It is a prostrate plant, with coriaceous glossy leaves with small pellucid dots, and of great value for planting in the shade.

H. ELATUM is a spreading species from North America (1762), growing to fully 4 feet in height, and bearing terminal corymbs of large, bright yellow flowers in July and August. Leaves rather large, oblong-ovate, and revolute. On account of its spreading rapidly from the root, this species requires to be planted where it will have plenty of room.

H. HIRCINUM.--Goat-scented St. John's Wort. Mediterranean region, 1640. A small-growing and slender species, with oblong-lanceolate leaves 2 inches long, and producing small yellow flowers in terminal heads. There is a smaller growing form known as H. hircinum minus. The plant emits a peculiar goat-like odour.

H. MOSERIANUM is a beautiful hybrid form with red anthers.

H. OBLONGIFOLIUM (_syns H. Hookerianum_ and _H. nepalensis_).--Nepaul, 1823. An evergreen species, about 4 feet high, with oblong, pellucid, dotted leaves, and deep golden, somewhat waxy flowers at the end of summer.

H. PROLIFICUM.--North America, 1758. This is a much branched twiggy shrub, about 4 feet high, with small, linear-lanceolate leaves, thickly studded with pellucid dots. Flowers not very large, five-petalled, and of a pleasing bright yellow colour. The allied if not identical H. Kalmiana is worthy of being included in a selection of these plants.

H. URALUM.--Nepaul, 1823. A neat but fragile species that attains to about a yard in height. Leaves rather small, elliptic, almost stalkless, and perforated with transparent dots. Flowers small and of a bright golden yellow.

H. fasciculatum, H. pyrimidatum, and H. patulum are all worthy of attention, where a good representative collection is of importance. The Hypericums succeed best when planted in a rather sandy and not too dry loam, and they are readily increased either from divisions or by means of cuttings.

IDESIA.

IDESIA POLYCARPA (_syns Flacourtica japonica_ and _Polycarpa Maximowiczii_).--A Japanese tree of small growth, and only introduced to this country in 1866. It is a handsome, hardy species, bearing large, bright-green leaves with conspicuous crimson footstalks, often 4 inches across, and of a glaucous tint on the under sides. The deliciously fragrant flowers are greenish-white or yellowish-green, and produced in graceful drooping racemes. In southern England it does well, and, being a tree of unusual beauty of both leaves and flowers, is well worthy of attention. Rich loam, not too stiff, will grow the Idesia well.

ILEX.

ILEX AQUIFOLIUM.--Common Holly. Europe (Britain) and West Asia. Though the Hollies are not usually reckoned ornamental for the sake of their flowers, their berries are highly so. Some of them are nevertheless deliciously fragrant when in bloom. The leaves of this, our native species, in their typical form are oblong-ovate, wavy, and deeply spiny-toothed. The tree flowers in May and June, while the clusters of bright red berries ripen in autumn, persist all the winter, and sometimes even hang on tree till a second crop is matured, provided they are not devoured by birds during severe weather. The varieties are very numerous, and differ chiefly in the form and toothing of the leaves, which are variegated in many cases, their size and form, and in the colour of the berries in a few instances.

I. Aquifolium albo-marginata has ovate, nearly flat, spiny-serrate leaves, with a narrow silvery margin, and fruits freely. I. Aquifolium fructu albo has white berries; in I. Aquifolium fructu luteo they are yellow and very abundantly produced; and in I. Aquifolium fructu nigro they are black. I. Aquifolium handsworthensis has elliptic-oblong spiny leaves, with a creamy-white margin and marbled with gray. Grafted trees bear berries in great profusion from the time they are only a foot high, and are highly ornamental. I. Aquifolium Hodginsii has large, broadly oblong-ovate, slightly spiny leaves, and large crimson-red berries that ripen late in autumn. I. Aquifolium Hodginsii aurea is a sub-variety with a broad golden margin to the leaves, and the disc splashed with gray. Beautiful and distinct is I. Aquifolium Lawsoniana, with ovate, flat, almost spineless leaves, heavily and irregularly blotched with yellow in the centre. The berries are of a brilliant red. The variety differs from Milkmaid in having flat, nearly entire leaves. I. Aquifolium pendula has a wide, rounded, drooping head, but otherwise does not differ from the type. Many others bear berries, but the above are all very distinct forms.

I. OPACA.--American Holly. United States, 1744. The leaves of this species are oblong or oval, small, spiny-serrate, and of a dark opaque green. The berries, which ripen in autumn, are small, bright red, and very liable to be eaten by birds. In America this Holly is put to precisely the same purposes as the common Holly is in Europe. It is perfectly hardy here.

ILLICIUM.

ILLICIUM FLORIDANUM, from Florida (1771), is a beautiful but uncommon shrub, probably on account of its being tender and susceptible to injury by frost, unless in the warmer and more favoured parts of the country. The fragrant flowers are of a purplish-rose, while the foliage is neat and of a pleasing green.
