Propagation

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

Seed - best sown as soon as it is ripe, the seed rapidly loses viability if it is allowed to become dry[2]. Surface sow and keep moist, it usually germinates in 1 - 3 months at 15°c[4]. Germinates in spring according to another report[2]. Two months warm, then a cold stratification improves the germination of stored seed[3][4]. Seedlings only produce one leaf in their first year of growth[5] and are very prone to damping off[2]. This species is a biennial and probably germinates more easily than the perennial species.

Cultivation

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

Prefers a moist, well-drained rather light soil, thriving in semi-shade[1]. Grows well in a woodland garden or peat bed. Plants seem to be immune to the predations of rabbits[9].
