BRYANTHUS.
BRYANTHUS ERECTUS.—Siberia. This is a pretty little Ericaceous plant, nearly allied to Menziesia, and with a plentiful supply of dark-green leaves. The flowers, which are borne in crowded clusters at the points of the shoots, are bell-shaped, and of a pleasing reddish-lilac colour. It wants a cool, moist peaty soil, and is perfectly hardy. When in a flowering stage the Bryanthus is one of the brightest occupants of the peat bed, and is a very suitable companion for such dwarf plants as the Heaths, Menziesias, and smaller growing Kalmias.
B. EMPETRIFORMIS (syn Menziesia empetrifolia).—North America, 1829. This is a compact, neat species, and well suited for alpine gardening. The flowers are rosy-purple, and produced abundantly.
BUDDLEIA.
BUDDLEIA GLOBOSA.—Orange Ball Tree. Chili, 1774. A shrubby species, ranging in height from 12 feet to 20 feet, and the only one at all common in gardens. Favoured spots in Southern England would seem to suit the plant fairly well, but to see it at its best one must visit some of the maritime gardens of North Wales, where it grows stout and strong, and flowers with amazing luxuriance. Where it thrives it must be ranked amongst the most beautiful of wall plants, for few, indeed, are the standard specimens that are to be met with, the protection afforded by a wall being almost a necessity in its cultivation. The leaves are linear-lanceolate, and covered with a dense silvery tomentum on the under side, somewhat rugose above, and partially deciduous. Flowers in small globular heads, bright orange or yellow, and being plentifully produced are very showy in early summer. It succeeds well in rich moist loam on gravel.
B. LINDLEYANA.—China, 1844. This has purplish-red flowers and angular twigs, but it cannot be relied upon unless in very sheltered and mild parts of the country.
B. PANICULATA (syn B. crispa).—Nepaul, 1823. This may at once be distinguished by its curly, woolly leaves, and fragrant lilac flowers. It is a desirable species, but suffers from our climate.
BUPLEURUM.
BUPLEURUM FRUTICOSUM.—Hare's Ear. South Europe, 1596. A small-growing, branching shrub, with obovate-lanceolate leaves, and compound umbels of yellowish flowers. It is more curious than beautiful.
CAESALPINIA.
CAESALPINIA SEPIARIA (syn C. japonica).—India, 1857. This is as yet a comparatively little known shrub, but one that from its beauty and hardihood is sure to become a general favourite. Planted out in a light, sandy, peaty soil, and where fully exposed, this shrub has done well, and proved itself a suitable subject for the climate of England at least. The hard prickles with which both stem and branches are provided renders the shrub of rather formidable appearance, while the leaves are of a peculiarly pleasing soft-green tint. For the flowers, too, it is well worthy of attention, the pinky anthers contrasting so markedly with the deep yellow of the other portions of the flower. They are arranged in long racemes, and show well above the foliage.
CALLUNA.
CALLUNA VULGARIS (syn Erica vulgaris).—Common Ling on Heather. This is the commonest native species, with purplish-pink flowers on small pedicels. There are many very distinct and beautiful-flowering forms, the following being some of the best: C. vulgaris alba, white-flowered; C. vulgaris Hammondi, C. vulgaris minor, and C. vulgaris pilosa, all white-flowered forms; C. vulgaris Alportii, and C. vulgaris Alportii variegata, the former bearing rich crimson flowers, and the latter with distinctly variegated foliage; C. vulgaris argentea, and C. vulgaris aurea, with silvery-variegated and golden foliage; C. vulgaris flore-pleno, a most beautiful and free-growing variety, with double flowers; C. vulgaris Foxii, a dwarf plant that does not flower freely; and C. vulgaris pumila, and C. vulgaris dumosa, which are of small cushion-like growth.
CALOPHACA.
CALOPHACA WOLGARICA.—Siberia, 1786. This member of the Pea family is of dwarf, branching growth, thickly clothed with glandular hairs, and bears yellow flowers, succeeded by reddish-purple pods. It is of no special importance as an ornamental shrub, and is most frequently seen grafted on the Laburnum, though its natural easy habit of growth is far preferable. Hailing from Siberia, it may be considered as fairly hardy at least.
CALYCANTHUS.
CALYCANTHUS FLORIDUS.—Carolina Allspice. Carolina, 1726. If only for the purplish-red, pleasantly-scented flowers, this North American shrub is worthy of extensive culture. The hardiness, accommodating nature, and delicious perfume of its brightly-coloured flowers render this shrub one of the choicest subjects for the shrubbery or edges of the woodland path. It is of easy though compact growth, reaching in favourable situations a height of 12 feet, and with ovate leaves that are slightly pubescent. Growing best in good fairly moist loam, where partial shade is afforded, the sides of woodland drives and paths will suit this Allspice well; but it wants plenty of room for branch-development. There are several nursery forms of this shrub, such as C. floridus glaucus, C. floridus asplenifolia, and C. floridus nanus, all probably distinct enough, but of no superior ornamental value to the parent plant.
C. OCCIDENTALIS.—Californian or Western Allspice. California, 1831. This is larger in all its parts than the former, and for decorative purposes is even preferable to that species. The flowers are dark crimson, and nearly twice as large as those of C. floridus, but rather more sparsely produced. This is a very distinct and desirable species, and one that can be recommended for lawn and park planting, but, like the former, it delights to grow in a rather moist and shady situation.
CARAGANA.
CARAGANA ARBORESCENS.—Siberian Pea Tree. Siberia, 1752. On account of its great hardihood, this is a very desirable garden shrub or small-growing tree. The bright-yellow, pea-shaped flowers are very attractive, while the deep-green, pinnate foliage imparts to the tree a somewhat unusual but taking appearance. Soil would not seem to be of much moment in the cultivation of this, as, indeed, the other species of Caragana, for it thrives well either on dry, sunny banks, where the soil is light and thin, or in good stiff, yellow loam.
C. FRUTESCENS.—Siberia, 1852. Flowers in May, and is of partially upright habit; while C. Chamlagii, from China, has greenish-yellow flowers, faintly tinted with pinky-purple.
C. MICROPHYLLA (syn C. Altagana), also from Siberia, is smaller of growth than the foregoing, but the flowers are individually larger. It is readily distinguished by the more numerous and hairy leaflets and thorny nature.
C. SPINOSA.—Siberia, 1775. This, as the name indicates, is of spiny growth, and is a beautiful and distinct member of the family. They are all hardy, and readily propagated from seed.
CARDIANDRA.
CARDIANDRA ALTERNIFOLIA.—Japan, 1866. With its neat habit, and pretty purple-and-white, plentifully-produced flowers, this is worthy of the small amount of care and coddling required to insure its growth in this country. Hailing from Japan, it cannot be reckoned as very hardy, but treated as a wall plant this pretty evergreen does well and flowers freely. It can, however, be said that it is equally hardy with some of the finer kinds of Hydrangea, to which genus it is nearly allied.
CARPENTERIA.
CARPENTERIA CALIFORNICA.—Sierra Nevada, California, 1880. This is undoubtedly one of the most distinct and beautiful of hardy shrubs. That it is perfectly hardy in England and Ireland recently-conducted experiments conclusively prove, as plants have stood unprotected through the past unusually severe winters with which this country has been visited. When in full bloom the pure-white flowers, resembling those of the Japanese Anemone, render it of great beauty, while the light gray leaves are of themselves sufficient to make the shrub one of particular attraction. The Carpenteria is nearly related to the Mock Orange (Philadelphus), grows about
