Prefers a rich well-drained loam that does not dry out rapidly in summer. Requires a very sunny position. This species is hardy to at least -15°c. Plants can take 4 – 5 years to flower when grown from seed. Plants seem to be immune to the predations of rabbits.
Seed – best sown as soon as it is ripe in early summer in a seed bed or a cold frame. Germination can be very slow, taking up to 18 months at 15°c. It is best to sow the seed thinly so that it is not necessary to transplant the seedlings for their first year of growth. Apply a liquid fertilizer during their first summer, however, to ensure they get sufficient nourishment. Prick out the seedlings once they are dormant, putting perhaps 2 plants per pot, and grow them on in a greenhouse or frame for at least a couple of years. Plant them out into their permanent positions when they are dormant. The seedlings take 4 – 5 years to reach flowering size. Division of the bulbs in June/July when the leaves have died down. Larger bulbs can be planted out direct into their permanent positions, though it is best to pot up the smaller bulbs and grow them on in a cold frame for a year before planting them out. The plant can be divided every other year if a quick increase is required.
