Cultivation Details

Prefers a cool position in a moist humus-rich soil[1]. Prefers an acid soil[200]. Grows well in light woodland[200] or in a shady position in the rock garden. This species is not very hardy in Britain according to one report[1], whilst another says that it is in climatic zone 7 and should therefore succeed outdoors in most parts of this country[200]. However, the leaves and the flowers are liable to be frost-damaged by autumn frosts[200]. A polymorphic species[1], it is closely related to S. stolonifera, differing in not having runners[200].

Propagation

Seed - we have no information for this species but suggest sowing the seed in a cold frame in the spring. Surface sow, or only just cover the seed, and make sure that the compost does not dry out. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first winter. Plant them out in late spring after the last expected frosts. Division in spring. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.
