This genus of 5 species of bulbs belongs to the hyacinth family (Hyacinthaceae) and occurs mainly in western North America. The Latin name Camassia comes from the Native American name, which is usually transliterated as Quamash. The meaning of the name is unclear, but what is known is that the edible bulbs were an important element in the diet of the native peoples. As garden plants they are tough and very adaptable, and 1 species, Camassia leichtlinii, has been extensively developed into garden forms. Camassia species have long narrow leaves, and in late spring and early summer they produce heads of 6-petalled flowers atop strong stems, rather reminiscent of some of the Agapanthus species.
CULTIVATION
The plants are mostly frost hardy and easily grown in fertile well-drained soil that does not dry out. Plant in full or half sun. Species may be raised from seed, but these take up to 5 years to bloom. Most garden plants are cultivars and may be propagated by division during winter.
Top Tip
These bulbous perennials are ideal for borders in temperate climates. The dead flowers tend to persist on the plant, so they need to be trimmed off periodically.
