A deciduous clump forming perennial with gentian-blue flowers in midsummer. Green foliage. A lovely plant for the border at approx. 40cm tall. Full sun in any fertile, well-drained soil.
Easily grown in average, medium, well-drained soil in full sun to part shade. Avoid wet, poorly drained soils. Plants may be trimmed back after flowering to revitalize and to encourage new foliage growth, with a resulting sparse and intermittent rebloom possibly occurring in late summer to fall.
