We have this plant on our prairie pasture frequently; most commonly along the gravel hillside and the gravel road going past our place. It volunteers quite easily and needs no seeding or help from us. It is really quite striking in large stands...I once found a stand along a railroad bed that was at least a hundred feet long and 12 feet wide - it was amazing!
Some Native American tribes collected it's seed for food and most first nation people used the "first season" roots - gathereed and dried for food. They were also adopted for food by the Europeans when they arrived.
They are great food plants for the birds and our pollinators - very important for all of us!
Thanks for stopping by - next time you're out along a gravel road or prairie remnant - look for this beautiful native prairie plant!
