Cult. This is rather a curious plant, and althoug) it is always 
treated as a frame shrub, it is nevertheless hardy enough to stand 
the winter in-a dry, warm, south border. A light, dry, sandy 
soil suits it best. It may be either increased by young cuttings 
planted in sand under a hand-glass, or by seeds.
