Aralia chinensis (Dimorphanthus) mandschurica.—Useful in some positions for its curious habit of growth and rather handsome foliage; quite hardy.
Aristolochia Sipho.—This has curious and inconspicuous flowers, which give this climbing plant its popular name of "Dutchman's Pipe." It can be grown on a wall, in which position, perhaps, its fine foliage is seen to the best advantage, but it is quite hardy and looks well climbing into a thin tree such as the Common Almond.
Berberis (Mahonia) Aquifolium.—A handsome plant at all times, and will even grow under the shade of trees.
Berberis Darwinii.—Very bright in flower. Young and sappy shoots get killed back in winter.
Berberis Thunbergi.—A most attractive Berberis; it makes a small neat-growing bush to which the adjective "sparkling" might be applied. Its chief glory is its autumnal foliage, and a large clump in September is "a sight to see"; quite hardy.
Berberis vulgaris.—Very beautiful when clustered with fruit. The purple-leaved variety (B. v. purpurea) is most useful for its foliage.
Betula alba purpurea.—A good foliage tree.
Buddleia globosa.—This does well in a warm sheltered spot facing south-west, where the morning sun in winter will not touch it too soon. It also objects to exposure to cold winds.
Calycanthus floridus.—Quite hardy, and grows well in half-shady places.
Ceanothus azureus.—This succeeds either trained to a wall or as a bush. In the latter case it should be in a sheltered position. It seems quite frost-proof, and its blue flowers are very beautiful at a time when few shrubs are in bloom (July and August). Its shoots should be well thinned, and those left shortened as soon as the buds begin to show signs of movement in the spring. The best form I have tried is Gloire de Versailles.
