HARDY WALL SHRUBS 51 



pale yellow, pink-tinted flowers. They like a pro- 

 portion of peat, and are propagated by layers, and also 

 by cuttings under a glass. Asimina triloba is another 

 shrub suitable for training on a wall, and grows to 

 about ten feet high. It is generally deciduous and has 

 purplish flowers, with some yellow towards the centre 

 of the blossoms. It is best propagated by layers, and 

 ought to have some peat or leaf-soil added to the loam. 

 Azara microphylla is a remarkably neat wall shrub, with 

 small evergreen leaves and greenish flowers of no 

 importance, succeeded by pretty little orange berries. 

 It is one of the prettiest small-leaved evergreens we 

 have. Integrifolia, Gilliesii, and dentata may prove 

 equally hardy, but have not been so well tested. 



Among the Berberises, or Barberries, there are a 

 number of species which are ornamental on low or 

 medium-sized walls, though so many of them do well 

 as bushes that there is less need to make use of them 

 in this way. B. nepalensis, or Mahonia nepalensis, is 

 very suitable, particularly because it really requires 

 such shelter in the north. The others need hardly be 

 named here, and this, like the rest of the Berberises, 

 is propagated by suckers, layers, cuttings, or seeds. 

 B. nepalensis has yellow flowers, and large, handsome 

 leaves. With a little shelter, even pretty far north, 

 the pretty Drimys Winteri, which is evergreen, and 

 has milky-white blossoms, may be grown against a 

 wall, and will cover a considerable space, but should 

 be kept well cut back to induce flowering, and is apt 

 to become a little untidy in its growth if neglected for 

 a time. Its sweet flowers are about an inch in diameter. 

 It prefers some peat and sand, and is grown from 

 cuttings of the half-ripe shoots in a cold frame, kept 

 close for a time. The pretty Buddleia globosa, the 

 Orange Ball, is a shrub which is always admired with 

 its balls of orange flowers. It is usually grown on
