These prairie cone flowers are easing their way into autumn, missing a few of their 4-12 petals, a little bent at the stems with leaves starting to turn ruddy. The cones are typically longer than the petals. They like it dry and hot and they self-seed. The leaves and stems are said to be analgesic, good for head and bellyaches. Decoctions are used to treat poison ivy and rattlesnake bites. Handy, eh?
I found these growing in Westcliffe, CO.
