This member of the sage family is gaining in popularity due to its ease of care, attractive appearance, and long bloom period. It forms dense clumps that reach 24 to 36 inches. Violet-colored spikes appear from early summer to mid fall. They will grow in any good soil but water- logged conditions should be avoided as well as excessively droughty conditions. It does best in full to part sun. It is very attractive planted in large masses and will also do well in a middle or back of the border location. It can be used as a cut flower. Staking may be needed in windy locations - especially in richer soils.
