Propagation

Seed - best sown in a shaded cold frame as soon as it is ripe[2][4]. 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[3]. The seedlings are prone to damp off and must therefore be given plenty of fresh air[3]. 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[3]. Division with care when the plants die down after flowering[4].

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Prefers a deep well-drained woodland or humus-rich soil in a somewhat shady position that remains moist in the summer[1][5]. Prefers a neutral to slightly acid soil[4]. Grows well in open woodland[1]. Succeeds in a sunny position if the soil does not dry out[5]. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[4]. Any transplanting is best done whilst the plants are in flower[4]. Plants can flower in two years from seed[3].
