How it is grown
Requires a very well-drained rich sandy loam and a sunny position. When the bulbs are planted about 15cm deep, they are generally hardy in Britain. Another report says that plants are hardy to -10°c or more if the drainage is perfect. This species is sometimes included in the genus Bessera.
Propagating it: Seed - best sown in a cold frame as soon as it is ripe. When large enough to handle, prick the seedlings out into individual pots and grow them on in a frame or greenhouse until large enough to go outdoors. Plant out whilst the plants are dormant in the autumn. Division of offsets when the plant is dormant in late summer.
