How to grow

Cultivation Grow in deep, fertile, moist, humus-rich soil. Slightly alkaline is preferable, but neutral and slightly acidic soils are suitable too. A position in full sun or partial shade is required

Propagation Propagate by seed in autumn or winter outdoors. Germination can take two or three years. Plants can also be propagated by division in autumn or early spring, just before the plant come back into growth. Aim to include one or several plump terminal buds with each division. The new plants can take two or three years to flower again as they dislike disturbance. It is also possible to take root cuttings in winter
