Camassia quamash is a spring-flowering bulb with striking blue-purple flower spikes that light up wet meadows and garden beds. Historically harvested and cultivated by Indigenous peoples of the Pacific Northwest for its nutritious bulbs, it thrives in moist conditions and makes an excellent pollinator plant.

Why grow it

Camas bulbs offer reliable spring color in wet meadows and rain gardens where many ornamental bulbs struggle, making it a practical choice for poorly drained sites. Compared to other moisture-loving spring bulbs, camas produces taller, more substantial flower spikes and establishes readily from bulbs without specialized chilling requirements in most climates. The edible bulbs also provide a dual-purpose harvest option for those interested in perennial food crops, though yields are modest.

Watch out for

Camas requires consistent moisture during its growing season and can decline in dry summers, so mulching helps retain soil moisture. Bulbs may take 2-3 years to reach flowering maturity from seed or small offsets, requiring patience before expecting full display. Division of established clumps is possible but often more effective done in late summer after foliage dies back.
