Propagation

The seed is best sown as soon as it is ripe in a cold frame. Sow stored seed in late winter in a cold frame. Germination is sometimes poor but should take place in 1 - 6 months at 15°c. The seedlings are very variable. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. The seed remains viable for about 12 months in normal storage[

Division in spring as growth commences. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.
