Hardy Ornamental Flowering Trees and Shrubs

by Angus D. Webster

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.
