Part 31

SHEPHERDIA.

SHEPHERDIA ARGENTEA.--Beef Suet Tree, or Rabbit Berry. North America, 1820. This shrub is rendered of particular interest on account of the intense silvery hue of the foliage. The leaves are narrow and lanceolate, silvery on both sides, and dotted over with rusty-brown scales beneath. The flowers, which are produced in April, are small and yellow, unisexual, or each sex on a distinct plant. Berries scarlet, about the size of red Currants, and ripe about September.

S. CANADENSIS.--North America, 1759. This is a small-growing, straggling species, fully 4 feet high, and clothed with rusty scales. The leaves are ovate or elliptic, and green above, and the flowers of an inconspicuous yellow, succeeded by orange-red berries.

SKIMMIA.

SKIMMIA FORTUNEI.--Japan, 1845. This is a neat-growing shrub, with glossy, laurel-like leaves, white or greenish-white flowers, and an abundance of scarlet berries in autumn. It succeeds best in a somewhat shady situation, and when planted in not too heavy peaty soil, but where abundance of not stagnant moisture is present.

S. JAPONICA (of Thunberg) (syn S. oblata).--Japan, 1864. A neat-growing, evergreen shrub, with rather larger and more showy leaves than the former, and spikes of pretty whitish, sweetly scented flowers. The female form of this is usually known as S. fragrans. What is usually known as S. oblata ovata, and S. oblata Veitchii, are only forms of the true S. japonica; while S. fragrantissima is the male of the same species. The beautiful, berried plant that has been exhibited under the name of S. Foremanii, and which is of very vigorous growth, and produces pyramidal spikes of sweetly scented flowers, is probably S. japonica, or a seminal variety. Another variety sent out under the name of S. macrophylla has unusually large leaves; and another named S. Rogersi produces fruit very abundantly.

S. LAUREOLA (syn Limonia Laureola), from the Himalayas, is an uncommon species, with very fragrant and pale yellow flowers.

S. RUBELLA (China, 1874) is another member of the family that has greenish-white, sweet-scented flowers, and which when better known will be largely planted.

SMILAX.

SMILAX ASPERA.--The Prickly Ivy. South Europe, 1648. A trailing-habited shrub, with prickly stems, ovate, spiny-toothed, evergreen leaves, and rather unattractive flowers. There are other hardy species from North America, including S. Bona-nox (better known as S. tamnoides), S. rotundifolia, and S. herbacea, the first being the most desirable. S. aspera mauritanica is a hardy variety, but one that is rare in cultivation, with long, wiry shoots, and well adapted for wall or trellis covering. They all require favoured situations, else the growth is short, and the plants stunted and meagre in appearance.

SOLANUM.

SOLANUM CRISPUM.--Potato-tree. A native of Chili, 1824, and not very hardy, except in the coast regions of England and Ireland. It grows stout and bushy, often in favoured places rising to the height of 12 feet, and has large clusters of purple-blue flowers that are succeeded by small, white berries. This is a decidedly ornamental shrub, that should be cultivated wherever a suitable place can be spared. It bears hard pruning back with impunity, and succeeds in any light, rich, loamy soil.

S. DULCAMARA.--Bitter Sweet, and Woody Nightshade. This is a native plant, and one of great beauty when seen clambering over a fence, or bank. It has long, flexuous stems, and large clusters of purple flowers, which are made all the more conspicuous by the showy yellow anthers. The scarlet fruit is very effective.

SOPHORA.

SOPHORA JAPONICA (syn Styphnolobium japonicum).--Chinese or Japanese Pagoda-tree. China and Japan, 1763. A large deciduous tree, with elegant pinnate foliage, and clusters of greenish-white flowers produced in September. Leaves dark-green, and composed of about eleven leaflets. S. japonica pendula is one of the most constant of weeping trees, and valuable for planting in certain well-chosen spots on the lawn or in the park.

S. TETRAPTERA.--New Zealand, 1772. This requires protection in this country. It is a valuable species, having numerous leaflets, and bearing racemes of very showy yellow flowers. S. tetraptera microphylla is a smaller-leaved variety, with ten to forty pairs of leaflets, and is known in gardens under the names of Edwardsia Macnabiana, and E. tatraptera microphylla.

SPARTIUM.

SPARTIUM JUNCEUM (syn S. acutifolium).--Spanish, or Rush Broom. Mediterranean region and Canary Isles, 1548. This resembles our common Broom, but the slender Rush-like branches are not angular, and usually destitute of leaves. The fragrant yellow flowers are produced abundantly in racemes, and when at their best impart to the shrub a very striking and beautiful appearance. For planting in poor, sandy or gravelly soils, or amongst stones and shingle, and where only a very limited number of shrubs could be got to grow, the Spanish Broom will be found an excellent and valuable plant. It is a native of Southern Europe, and is quite hardy all over the country. Propagated from seed.

SPIRAEA.

SPIRAEA BELLA.--Pretty-flowered Spiraea. Himalayas, 1820. The reddish stems of this rather tall-growing species are of interest, and render the plant distinct. Leaves ovate, acute, and serrated, and tomentose beneath. Flowers in spreading corymbs of a very beautiful rose colour, and at their best from the middle of May till the middle of June. S. bella alba has white flowers.

S. BLUMEI.--Blume's Spiraea. Japan. This is a Japanese species, growing 4 feet or 5 feet high, with small, ovate, bluntly-pointed leaves, and white flowers arranged in compact terminal cymes. It is a good and worthy species for ornamental planting.

S. BULLATA (syn S. crispifolia.)--Japan. This will ever be accounted valuable for the rock garden, owing to its very dwarf habit and extreme floriferousness. It bears tiny bunches of bright rose-coloured flowers, and these look all the more charming owing to the miniature size of the shrub, its average height being about 12 inches. A very interesting and valuable rock shrub, and one that no doubt about its perfect hardihood need be entertained.

S. CANA.--Hoary-leaved Spiraea. Croatia, 1825. This is a small spreading shrub that rarely rises to more than 18 inches in height, with small, ovate, hoary leaves, and pretty white flowers arranged in corymbs. For rockwork planting it is one of the most valuable species, growing freely and producing its showy flowers in abundance. Quite hardy.

S. CANTONIENSIS (syn S. Reevesiana).--Reeve's Spiraea. Japan, 1843. An evergreen or sub-evergreen species, growing 3 feet high, with lanceolate leaves on long footstalks, and large, pure white flowers arranged in terminal corymbs, and placed on long peduncles.

S. CHAMAEDRIFOLIA (syn S. ceanothifolia).--Germander-leaved Spiraea. South-eastern Europe to Japan, 1789. Grows about a yard high, with ovate, pubescent leaves, and white flowers. It varies widely in the shape and size of leaves. S. chamaedrifolia ulmifolia (Elm-leaved Spiraea) a twiggy shrub, 3 feet high, with broad leaves and white flowers, is from Siberia. S. chamaedrifolia crataegifolia (Hawthorn-leaved Spiraea) is of stout, half-erect growth, with rather stiff glaucous leaves that are oval in shape, and bright red or pink flowers in fastigiate panicles. From Siberia 1790, and flowering at mid-summer.

S. DECUMBENS (syn S. nana).--Decumbent Spiraea. Tyrol. This is the smallest-growing of the shrubby Spiraeas, rarely attaining to a greater height than 12 inches. It is a neat growing plant, with small oval leaves, and white pedunculate flowers. For planting on the rockwork or in the front line of the shrubbery, this is an invaluable shrub, and soon forms a neat and pretty specimen. It is perfectly hardy.

S. DISCOLOR ARIAEFOLIA (syn S. ariaefolia).--White Beam-leaved Spiraea. North-west America, 1827. This forms a dense, erect shrub about 6 feet high, with elliptic-oblong leaves, and clothed beneath with a whitish tomentum. The flowers are in large, terminal, slender-stalked panicles, and white or yellowish-white. It is one of the handsomest species in cultivation, the neat and yet not stiff habit, and pretty, plume-like tufts of flowers making it a general favourite with the cultivators of hardy shrubs. Flowers about mid-summer. In rich soils, and where partially shaded from cold winds, it thrives best.

S. DOUGLASII.--Douglas's Spiraea. North-west America. This has long, obovate-lanceolate leaves, that are white with down on the under surface, and bears dense, oblong, terminal panicles of rosy flowers. S. Douglasii Nobleana (Noble's Spiraea) is a variety of great beauty, growing about a yard high, with large leaves often 4 inches long, and looser panicles of purple-red flowers. Flowering in July. The variety was introduced from California in 1859.
