Bloom season: In summer, tiny coppery-brown flowers are held in rounded clusters at leaf tips.
Exposure: Full sun or partial shade.
Pruning needs: None; shabby foliage can be cut flush to the ground in late winter to encourage fresh growth.
Water needs: Low; once established, water deeply once or twice a month.
Snapshot: Rushes and other grasslike plants are valued for their narrow foliage and contrasting forms, and this variety is no exception. Totally vertical and almost tubular in shape, the blue-gray foliage will grow into a rounded clump. Elk Blue looks very attractive against pale blue succulents or apple-green ground covers. Native to the Central Valley, this species is fairly drought tolerant. It also can be grown in “rain gardens” and damp areas where its roots – or, in rainy winters, much of the whole plant – may be submerged for extended periods.
