The plants have tall spikes of purple flowers resembling bottle brushes or feathers that grow 1–5 ft tall. The species grows in hardiness zones 3 - 8, stretching from the Midwest to the East Coast, eastern and western Canada.

Common varieties include 'Alba' and 'Floristan White' which are white-flowering cultivars on 18 in tall spikes, 'Callilepsis' with long stems good for cut flowers, 'Floristan Violett' with a strong stem and thick, violet flower spikes preferred by florists, and 'Kobold' which stays small in size with deep purple flowers.


"Liatris spicata" var. "resinosa" is found in the southern part of the species's natural range. The variable plants have only 5 or 6 flowers per head and the heads are more widely spaced on the stems; these differences are more pronounced when the plants are found in drier and coastal habitats.


"Liatris spicata" was historically used medicinally by Native Americans for its carminative, diuretic, stimulant, sudorific, and expectorant properties. In addition to these uses, the Cherokee used the plant as an analgesic for pain in the back and limbs and the Menominee used it for a "weak heart." The root of the plant is the part most often used. Native Americans also used the plant to treat swelling, abdominal pain and spasms/colic, and snake bites. Currently, the plant is used for a sore throat by gargling an infusion, as an herbal insect repellent, and in potpourri.
