Prairie Thistle (Cirsium discolor)

Beautiful purple flowers stand out in the summer prairie, attracting pollinators when in flower and birds for the seed. This thistle gets a bad wrap because it looks similar to some of the non-native invasive thistles, however this native species is a biennial or short-lived perennial and only spreads by seed... it is not considered aggressive at all and is an important plant of many Illinois prairies.
