How it is grown
Landscape Uses:Alpine garden, Container, Rock garden, Woodland garden. Prefers slightly acid soil conditions but succeeds in chalky soils if these contain plenty of humus. Requires semi-shade, preferably provided by trees or shrubs, and a well-drained soil. Succeeds in almost any light soil, preferring one that is rich in humus. Plants are hardy to at least -15°c. Plants are spreading well, but only flowering lightly in the dappled shade of a woodland garden at Kew. Bulbs should be planted about 7cm deep. They increase rapidly by offsets. Special Features: Attractive foliage, North American native, Naturalizing.
Propagating it: Seed - best sown as soon as it is ripe in a shady position in a cold frame. Water lightly in summer, it should germinate in autumn or winter. Stored seed requires a period of cold stratification. Sow as early in spring as possible in a cold frame. Sow the seed thinly so that it will not be necessary to prick them out for their first year of growth. Give an occasional liquid feed to the seedlings to make sure that they do not become nutrient deficient. When the plants are dormant, pot up the small bulbs putting 2 - 3 bulbs in each pot. Grow them on in a shady position in the greenhouse for another 2 3 years and then plant them out into their permanent positions when they are dormant in late summer. Division of the bulbs in the summer as the leaves die down. Larger bulbs can be replanted immediately into their permanent positions, but it is best to pot up smaller bulbs and grow them on in a shady position in a greenhouse for a year before planting them out when dormant in late summer.
