Tall spikes of large violet-blue flowers appear in April & May. Camassia l. Caerulea will form clumps and gradually spread so plant them somewhere they can naturalise happily and be left to die down naturally after they flower. As Camassia is a tall growing bulb, they will tolerate been planted in wild and grassy areas. Camassia leichtinii (the white form of this plant) can be found in the mountain meadows of north western USA in full sun but they will also do well in part shade. Grow in moist but well-drained, fertile, humus-rich soil with some protection from hard frosts, a layer of mulch will help Camassia to overwinter successfully.
