Crataegus Lelandii is a handsome Thorn, the chief beauty of which is the crop of handsome scarlet berries which it carries through the winter. It is superior to the old "Pyracantha".
The Japanese Quince, Cydonia, Or Pyrus Japonica, is doubly handsome, for its large scarlet flowers, as big as Apple blossom, make the house wall brilliant in spring, while its fruits are beautiful in autumn. This is a particularly valuable wall shrub, because it will thrive in most soils and on most aspects. The flowering sprays may be cut for room decoration, and the buds will open in water. The fruit may be cooked, or made into jelly. There are several distinct varieties, notably Apple Blossom, pink and white; Simonii, crimson; and Maulei, terra-cotta. The last named is suitable for a low wall.
The Escallonias grow with great luxuriance in mild, moist places, and form beautiful hedges of shining foliage and rosy flowers in some cliff gardens that I wot of overlooking Mounts Bay. Macrantha is the typical species. Langleyensis has carmine, and Philippiana white flowers. All are evergreen.
Garrya Elliptica is perhaps rather distinct than beautiful. It bears long, pendulous, pale green catkins in spring. It is an evergreen.
The Honeysuckles (Lonicera Of Botanists) are naturally popular, with their pretty flowers and delicious perfume. There are several varieties of the common Woodbine, notably Belgica, rose and cream, and Pallidum, creamy yellow; both of these are hardy, and fragrant to a degree. They lose their leaves in winter. The Japanese (Japonica Flexuosa), with red and white perfumed flowers, is an evergreen. There is a netted-leaved form of the Japanese called Aureo Reticulata which has yellow in the foliage, and is a very ornamental plant. Fragrantissima and Standishi bear white flowers in winter.
The Ivies (Hedera Of Botanists) are perhaps mostly represented nowadays by the small-leaved, parti-coloured sorts, of which Chrysophylla (Mrs. Pollock), Dentata Variegata, and Marginata Robusta are a good trio. They do not grow so fast as the Irish Ivy (Canariensis), and if a green-leaved kind that will cover a house wall quickly is wanted, the latter had better be selected. The plants should be clipped over in spring.
The most useful of the Jasmines is certainly the yellow winter-bloomer Nudiflorum, as it is perfectly hardy. Humile (Revolutum) is both beautiful and sweet, but is not quite hardy. Jasmine lovers who have a heated greenhouse should make acquaintance with the beautiful evergreen winter-flowering species Primulinum, which bears a profusion of yellow flowers.
The Double Yellow Jew's Mallow (Kerria) is a very useful wall shrub, as it will thrive on most aspects, and is covered with double yellow flowers in summer.
