Hardy Ornamental Flowering Trees and Shrubs Part 21

RUSCUS.

RUSCUS ACULEATUS.--Butcher's Broom, Pettigree and Pettigrue. Europe (Britain), and North Africa. This is a native evergreen shrub, with rigid cladodes which take the place of leaves, and not very showy greenish flowers appearing about May. For the bright red berries, which are as large as small marbles, it is alone worth cultivating, while it is one of the few shrubs that grow at all satisfactorily beneath the shade of our larger trees.

R. HYPOPHYLLUM.--Double Tongue. Mediterranean region, 1640. This species has the flowers on the undersides of the leaf-like branches; and its variety R.H. Hypoglossum has them on the upper side. Both are of value for planting in the shade.

SAMBUCUS.

SAMBUCUS CALIFORNICA.--Californian Elder. A rare species as yet, but one that from its elegant growth and duration of flowers is sure, when better known, to become widely distributed.

S. GLAUCA has its herbaceous parts covered with a thick p.u.b.escence; leaves p.u.b.escent on both sides, and with yellow flowers produced in umbels.

S. NIGRA.--Common Elder. Bourtry, or Bour tree. Although one of our commonest native trees, the Elder must rank amongst the most ornamental if only for its large compound cymes of white or yellowish-white flowers, and ample bunches of shining black berries. There are, however, several varieties that should be largely cultivated, such as S. nigra foliis aureis (Golden Elder), S. nigra fructu albo (White Fruited), S.

nigra laciniata (Cut-leaved Elder), S. nigra argentea (Silver-leaved Elder), S. nigra rotundifolia (Round-leaved Elder), the names of which will be sufficient for the purposes of recognition.

S. RACEMOSA.--Scarlet-berried Elder. South Europe and Siberia, 1596.

This is almost a counterpart of our native species, but instead of black the berries are brilliant scarlet. It is a highly ornamental species, but it is rather exacting, requiring for its perfect growth a cool and moist situation. Of this there is a cut-leaved, form, named S. racemosa serratifolia.

S. ROSAEFLORA is said to be a seedling from S. glauca, but differs in many important points from the parent. It has smooth shoots and branches, ovate-ac.u.minate leaves that are downy beneath, and flowers rose-coloured without and white within. They are produced in short, spike-like cl.u.s.ters, and are almost dest.i.tute of smell. The reddish rings at the insertion of the leaves is another distinguishing feature.

For freedom of growth in almost every cla.s.s of soil, and readiness with which they may be increased, the more showy kinds of Elder are well worthy of attention.

SCHIZANDRA.

SCHIZANDRA CHINENSIS.--Northern China, 1860. This is a climbing shrub, with oval, bright green leaves, and showy carmine flowers. For clothing arbors and walls it may prove of use, but it is as yet rare in cultivation.

S. COCCINEA, from North America (1806), is another uncommon species in which the leaves are oblong and petiolate, and the flowers red or scarlet. For purposes similar to the last this species may be employed.

SCHIZOPHRAGMA.

SCHIZOPHRAGMA HYDRANGEOIDES.--Climbing Hydrangea. j.a.pan, 1879. As yet this is an uncommon shrub, and allied to the Hydrangea. It is of slender growth, the stems rooting into the support, and with pinky-white flowers. As an ornamental climber it is of no great value, and requires a favoured spot to grow it at all satisfactorily.

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, unis.e.xual, or each s.e.x 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.--j.a.pan, 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. j.a.pONICA (of Thunberg) (_syn S. oblata_).--j.a.pan, 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. j.a.ponica; 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. j.a.ponica, 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 p.r.i.c.kly Ivy. South Europe, 1648. A trailing-habited shrub, with p.r.i.c.kly 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 cl.u.s.ters 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 cl.u.s.ters of purple flowers, which are made all the more conspicuous by the showy yellow anthers. The scarlet fruit is very effective.

SOPHORA.

SOPHORA j.a.pONICA (_syn Styphnolobium j.a.ponic.u.m_).--Chinese or j.a.panese PaG.o.da-tree. China and j.a.pan, 1763. A large deciduous tree, with elegant pinnate foliage, and cl.u.s.ters of greenish-white flowers produced in September. Leaves dark-green, and composed of about eleven leaflets. S.

j.a.ponica 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 dest.i.tute 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. j.a.pan. This is a j.a.panese 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_.)--j.a.pan. 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.--h.o.a.ry-leaved Spiraea. Croatia, 1825. This is a small spreading shrub that rarely rises to more than 18 inches in height, with small, ovate, h.o.a.ry 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. j.a.pan, 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.
