Propagation

Seed - best sown in a shaded cold frame as soon as it is ripe[134, 200]. Stored seed should be sown in late winter or early spring. Seed usually germinates within 1 - 3 months at 15°c. Another report says that seeds produce a root after the first cold stratification but no shoot is produced until after a second winter[138]. The seedlings are prone to damp off and must therefore be given plenty of fresh air[138]. The young plants need to be overwintered in a cold frame for the first year and can then be planted out in late spring. It is very important that the pots become neither too dry nor too wet[138]. Division with care when the plants die down after flowering[200].
