How to grow
Cultivation
Plant 8-10cm deep in fertile, humus-rich, moist but well-drained and preferably sandy soil in full sun or partial shade; in colder areas plant somewhere with shelter from cold drying winds, such as near a wall, and protect in winter with a thick, dry, organic mulch; if clumps become congested, divide them in early spring. Has the potential to become a nuisance in some gardens if not managed well
Propagation
Propagate by division of established clumps in spring, just before new growth starts
