About the purple coneflower

  • Purple coneflowers are perennial herbaceous plants that have pink to purple flowers with orange centers.
  • They attract many pollinators when they flower in mid-summer to early fall. 
  • The flowers produce spiny seeds that are a fall food source for birds. 
  • These plants grow in the western half of Minnesota. 
  • The purple coneflower, or echinacea, is a part of traditional Native American medicine. It also appears in commercially available herbal supplements for colds and flu.
