An attractive perennial grown for both its edible, cucumber-flavored leaves and its medicinal (astringent) properties. An easy-growing plant that appears early in the season and holds up well in heat. It forms a clump with small, dense, purple flowers on 12” or greater spikes. Though self-seeding, young plants are easy to remove. Tolerates a range of soils but grows best in moderately moist conditions. Plant in full sun or part shade and water regularly.
