PRUNUS TRILOBA AGAINST SUNNY WALL AT KEW.
Punica (Pomegranate).—Both single and double.
Pyrus.—The Pyruses are described elsewhere in this book. P. (Cydonia) japonica and its many beautiful varieties, and P. Maulei are, however, more frequently grown against walls than any other members of the same family. Prunus triloba is an excellent wall shrub.
Raphiolepis ovata.—A very handsome plant.
Rosa (Rose) (see p. [342]).
Rubus (see p. [450]).
Smilax.—This group is not common in gardens, but is interesting. They are a change from the repetition of a few common things. S. rotundifolia is a very handsome large-leaved Smilax with shiny foliage, now and then met with as S. laurifolia or S. latifolia, from which, however, according to Mr. R. Irwin Lynch, of Cambridge, it is distinct. All the kinds of hardy Smilax form handsome leafy creepers for walls, but in our climate they rarely produce the rich clusters of red berries that often render them so attractive abroad.
Solanum.—S. jasminoides is the most popular flowering climber of the south-west, producing its white bloom-clusters for many months in succession. It is classed as deciduous in botanical dictionaries, but is rarely bare of leaves, except after severe frosts in the early months of the year. S. crispum and S. Wendlandi will also succeed in mild counties; the latter has very large bluish flowers.
Stauntonia latifolia (syn. Holbœllia latifolia).—This plant bears clusters of small greenish-white, highly-fragrant flowers in March, and often perfects seed-pods in the autumn. It is a rapid grower, and its leathery leaves are rarely affected by frost.
Stuartia pseudo-Camellia.—A rare and very beautiful flowering shrub now seldom seen in even the best of gardens. It is a native of Japan, the flowers being ivory white and perfectly cup-shaped, somewhat like a single White Camellia. S. pentagyna comes from North America, as also S. virginica, but the first-named is the finest and is worth a good deal of trouble to grow well. Planted in loam and peat and sand at the foot of a sunny and sheltered wall, the flowering shoots may be preserved intact during the winter. Perfect drainage is absolutely essential for the first-named.
