Found in prairies and dry, open woods. Blooms late May to October. Other species commonly found in the area are E. angustifolia and E. pallida. E. pallida blooms May to June.
Purple coneflower grows from 2 to nearly 4 feet tall, but other species may be from 2-3 feet tall. The ovate to lineolate lower leaves have toothed edges and are very rough to the touch. The upper leaves and leaves of other species are without toothed edges. Leaves are 3-8 inches long and 1-3 inches wide.
The plant grows from a thick, grayish brown to black perennial root. The furrowed or ridged rootstock is ¼ to ½ inch in diameter.
The flower head has 12-20 spreading or drooping, purple, petal-like rays. Rays occasionally vary from purple to crimson and rarely are pale. Each ray is 1 ½ to 3 inches long. The center cone is more dome-shaped than cone-shaped, and it is rough and prickly to the touch. The entire flower may be 3 to 3 ½ inches across. The rays of a more southern species, E. paradoxa, are bright yellow.
Plains Indians favored the root of purple coneflower for snakebites, bee stings, headaches, stomach cramps, toothaches, enlarged glands such as mumps, sore throats and hydrophobia and doe distemper in horses. The Sioux used freshly scraped root (as a poultice) for snakebite and for the bite of a mad dog, and they chewed pieces of rootstalk for toothache.
American Indians discovered that the plant was somewhat like a burn preventative and enabled the body to endure extreme heat. Medicine men bathed their hands and arms in the juice, the picked out meat from boiling stew. Sometimes it was used prior to sweat baths and ritual feats such as immersing hands in scalding water or holding live coals in the mouth.
A smoke treatment was used for headache in humans and for distemper in horses.
Early doctors thought purple coneflower made the body more resistant to infection, and they often used it to induce profuse sweating. They believed it has a bright future as a medicinal drug source. Modern medicine still uses extracts from this plant for treating wounds and sore throats.
The root of E. angustifolia has been used by the Plains Indians as a pain killer for toothaches and sore throats, since chewing the root causes the throat, tongue and jaw to be numbed. It has also been used as a blood purifier and the treat snakebite, blood poisoning and cancer. Burns were bathed in E. pallida juice to give relief from pain.
