Nearly 8-inch-wide globes of tiny star-shaped purple flowers bloom from late spring to early summer, rising up to 4 feet in height. Thrives in sunny, hot locations with well-draining soil and drought tolerant when established. Grass-like foliage smells like onions when crushed, keeping it deer and rabbit resistant. Highly attractive to pollinators. Spent flowers become dried seed heads that can be used in arrangements.
