wholeleaf rosinweed, Silphium integrifolium

Gerber Hill County Park includes a planted prairie. At this time of year it shows us a bunch of flowers from the aster family. This wholeleaf rosinweed is mostly a plant of actual prairies. It's finishing up now, and getting a little unorganized. In the case does that add to the interest? It probably shows up there because of its rep of being easy to grow. It's wild in AL, AR, CO, IA, IL, IN, KS, KY, LA, MI(T), MN< MO, MS, NE, NM, OK, SD, TN, TX, WI, WY, and ON. Lenawee Co MI, 9/13/20. Aster Family, Asteraceae.
