HARDY WALL SHRUBS 61 



blue flowers, is the prettiest of these, and a large plant 

 in full bloom is worth going a long way to see. There 

 is a variety called angustifolium, which differs slightly. 

 These are fairly hardy. S. jasminoides, with white 

 flowers, makes a good companion, but is more tender. 

 They grow in common soil, and are propagated by 

 cuttings struck under a glass. In favoured gardens 

 the Stuartias are cultivated with success on warm walls, 

 where the wood can be properly ripened. They prefer 

 a little peat in the soil, and are increased by layering, 

 and also by cuttings of ripe wood under a glass in 

 sandy soil. 



S. pentagyna, creamy-white, and S. virginica, white, 

 are the most generally grown, but S. pseudo-Camellia, 

 or Grandiflora, is also to be valued for its creamy-white 

 flowers. Vitex Agnus-castus, the Chaste Tree, or 

 Monk's Pepper, which has pale lilac flowers, should 

 have a wall except in the south, and is referred to for 

 the sake of some who might wish to grow this old 

 plant in the open. The Viburnums of tall habit make 

 very ornamental wall shrubs and can be cultivated in 

 practically any good soil. They are propagated by 

 cuttings of the partially ripened growths in shade 

 under a hand-light or by layers. The pretty blue- 

 flowered Vinca major, a tall Periwinkle, looks well 

 on a low trellis, fence, or wall. 



Aristotelia Macqui is a neat shrub of moderate height 

 which has green flowers, followed by black berries. 

 The variegated form is a neat shrub and their evergreen 

 habit is an advantage for some positions. A. Macqui 

 is propagated by layers or cuttings and does well in 

 any common soil. Desfontainea spinosa is prized for 

 its evergreen leaves and its tubular scarlet and yellow 

 flowers. It prefers some peat in the soil and is raised 

 from cuttings in heat under a glass. Of the Enkian- 

 thuses, which are neat wall shrubs, campanulatus and
