How to Grow
Succeeds in a shady crevice of a cool rock garden in a humus-rich well-drained acidic soil. This species is not quite hardy when grown outdoors in Britain and is best grown in the alpine house or with some protection when grown outdoors. A pane of glass to cover the plant is probably sufficient.
Propagation: Surface sow seed as soon as it is ripe in a greenhouse, keeping pots consistently moist and providing artificial light through winter. Seed can also be surface sown in spring. Prick seedlings into individual pots once large enough to handle and grow on in the greenhouse for at least their first winter before planting out in late spring or early summer after the last expected frosts. Can also be propagated by division in spring.
