How to grow it
Liatris spicata is a garden flower in many countries around the world, grown for its showy purple flowers (pink or white in some cultivars). They bloom in July through August or September, depending on where in their range they are located.
Under cultivation it is found under many names including button snakewort, Kansas gay feather, blazing star, Liatris callilepis.
Uses
Liatris spicata was historically used medicinally by Native Americans as a carminative, diuretic, stimulant and expectorant herb. 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 heart issues. The root/corm 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.
