Cultivation Details

HabitBulb
Growth—

An easily grown plant, succeeding in an ordinary garden soil[5, 6]. Tolerates partial shade[7]. Hardy to about -20°c[7]. The dormant bulbs are very hardy and will withstand soil temperatures down to at least -10°c[8]. A very ornamental plant[5], but it can be invasive where conditions suit it[7]. It can be naturalized in short turf or thin grass below shrubs[7], though this should not be mown from the time the bulbs start to grow until they have set seed and the leaves are dying down.

Propagation

Seed - best sown as soon as it is ripe in a cold frame[7]. Sow the seed thinly and leave the seedlings undisturbed in the pots for their first dormancy, but apply liquid feed at intervals, especially in their second year of growth. Divide the bulbs at the end of their second year of growth, putting 2 - 3 bulbs in each pot. Grow them on for one more year and them plant them out into their permanent positions whilst they are dormant. The seed can also be sown in a cold frame in early spring. Division of offsets in September/early autumn[7]. The larger bulbs can be replanted immediately into their permanent positions. It is best to pot up the smaller bulbs and grow them on for a year before planting them out when dormant in late summer.
