Bloom Time Very Late
Bloom times are relative within the spring bulb season, which varies from place to place and year to year. They are intended to help you plan a sequence of bloom from Very Early season to Very Late season. About two weeks separate Early from Mid and Mid from Late. The start and duration of bloom is heavily dependent on the weather. Warm temperatures speed up growth and flowering; cold temperatures slow them down.

Planting Instructions

Plant in full sun or light shade and well-drained soil. Sandy soil is ideal. Allium leaves will yellow by the time the flowers open. You can disguise the foliage by planting large alliums among bushy perennials or shrubs, and small alliums among low-growing perennials. The flower heads of large-headed alliums remain attractive even after the color fades. They can be left in the garden or cut and dried for use in indoor arrangements. Species alliums (e.g., siculum, moly) may self-sow.
