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]. Sow the seed thinly so that the seedlings can be allowed to grow undisturbed in the pot for their first year. Apply liquid feed at intervals during their growing season to ensure they are well fed. The seedlings only produce one leaf in their first year of growth[5] and are very prone to damping off[2]. Divide the seedlings into individual pots once they have become dormant and grow them on in a partially shaded area of a greenhouse for at least another year. Plant them out into their permanent positions when they are dormant. Division after flowering.

Cultivation

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

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. This species belongs to the section 'Fasciculatae' of the genus. The roots of many, if not all the species in that section, are eaten in the Himalayas[5]. The following notes are based on the general needs of the genus. 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[7].
