The interesting aspect of this plant is its seedhead. 'Prairie Smoke' describes this unique plant perfectly!
A spring-blooming North American native prairie plant. Native Americans once boiled the roots to produce a root tea that was used medicinally for a variety of purposes such as wound applications and sore throat treatments.
This is planted in The Lurie Garden at Millenium Park.
Will reseed in your garden. Spreads by rhizomes and can be naturalized to form an interesting ground cover.
