Starry, purplish blue flowers rise in loose spikes on tall stems. Camassia is most effective when planted in clusters in a shrub border or grassy area, where it looks perfectly natural. It needs full sun and thrives in damp, or even wet, soil.
Note: Camassia is resistant to deer, but rodents such as voles and gophers may eat the bulbs.

Plant in full sun or light shade and evenly moist soil. Camassias are among the few bulbs that thrive in damp, or even wet, soil. Foliage is slow to die back in summer; do not cut before it has completely yellowed and collapsed.
Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.
Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.
