Deciduous compact, clump-forming perennial with aromatic, grey-green leaves and dense, erect spikes of purple-blue flowers in summer. Attractive to pollinating insects.
Grow in light, moderately fertile, humus-rich, moist but well-drained soil. Mulch in spring. Best in full sun but can tolerate light partial shade. Drought-tolerant once established. Deadhead flower spikes as they fade to prolong flowering.
