HARDY WALL SHRUBS 49 



Others will be found in the table of plants at the end. 

 All are desirable, and require a light soil, and are pro- 

 pagated by layers, suckers, or by cuttings, struck under 

 glass. They should be thinned out and kept trimmed 

 to prevent them from growing rough. 



The wall is the proper place in colder districts for 

 the greater number of the gloriously beautiful Magnolias, 

 especially of the evergreen species, which want its 

 protection from wintry winds. Of course grandiflora, 

 with its several varieties, grows to a great size, and 

 thus needs plenty of room, but it is so fine as a wall- 

 plant that those who have space and cannot grow it in 

 the open may well give it a station on a tall building. 

 The dwarfer glauca, also with white flowers, requires 

 a smaller space, as its full height is about fifteen 

 or sixteen feet. All the deciduous species such as 

 conspicua, the Yulan, can be trained to a wall also, 

 and this is a desirable plan for places where cold 

 winds often prevail in spring. M. conspicua soulan- 

 geana is a pretty form of that well-known species, 

 with purple-tinted blooms. The Magnolias like a good 

 soil, but must have ample drainage. A favourite old 

 wall plant is the deciduous Kerria japonica, whose 

 double variety is one of the easiest of deciduous wall 

 shrubs to grow, and which will give its double yellow 

 flowers as freely in a shady wall as on a sunny one. If 

 neatly trained it requires little attention, and will thrive 

 in ordinary soil. It is propagated by layers, cuttings, or 

 division. This yellow-flowered shrub reminds us by its 

 colour of two antipodean plants, Corokia buddleoides 

 and C. Cotoneaster, though the flowers of the former 

 are in panicles, and both are evergreen in their habit. 

 They are a little tender, and are increased by layers or 

 by cuttings in a frame in autumn. The first is taller 

 than the second, which is a low shrub, the other 

 growing to ten feet or more in height. A class of
