Herbaceous kinds increased by seeds sown from June to August on pans of light, sandy soil, which should be soaked with water before sowing.

The glass can then be gradually removed. The shrubby kinds, by seeds and by cuttings in August. Place in a cold-frame facing the north, in sandy soil, and when rooted, pot off into 3-inch pots. Place in a light, sunny frame, where they may remain until the middle of February.
