The scientific name for the coneflower is Echinacea, which comes from the Greek word (ἐχῖνος) for hedgehog.
They only grow in North America.
Echinea purpurea — purple coneflowers — are the most common.
North American Indigenous peoples, including the Kiowa, the Cheyenne, the Pawnee, and the Lakota, all utilized coneflowers as medicine, especially for sore throats and pain.
