Division in spring.
Seed sown in January - March.
Seed just covered and kept at 20°C (68°F) until germination. Germination can be slow and take several months. After germination it should be kept at a lower temperature with plenty of light so the plants won't become lanky.
Beautiful woodland plant that grows best in well drained, humus rich soil, in dappled shade.
