Native to North America, Camassias (Camas) are bulbous perennials with long racemes of up to 100 star-shaped flowers, adorned with six slender loose petals, a green center, and bright yellow stamens. Borne on stout, willowy stems, they open sequentially from bottom to top for a long-lasting display. Blooming in late spring to early summer, these spring-flowering bulbs add something different to the borders at a time when the summer perennials have not yet hit their stride. Left undisturbed, they will multiply freely in damp soil. Unlike most other bulbs, they prefer moisture-retentive soil and are even happy in light shade. Easy to grow, deer and rodent-resistant.
