I’m thrilled to share another talented photographer’s images of a native plant I’ve never seen. Wildflower enthusiast Katie Byerly found these plants growing in Rock Falls (Cerro Gordo County) in September. Experts in the Iowa Wildflower Report Facebook group confirmed her identification of Riddell’s goldenrod (Oligoneuron riddellii), an uncommon species mostly found in Midwestern states and a couple of Canadian provinces.
The scientific name used to be Solidago riddellii, but Leland Searles explained to me, “The genus was changed to Oligoneuron for Riddell’s and Stiff Goldenrods (O. rigidum). They are unlike genus Solidago [most other goldenrods] in several ways.”
Katie went back to Rock Falls a few days ago, hunting for witch hazel after reading Beth Lynch’s post here last week. She had also hoped to find some Riddell’s goldenrod gone to seed. Alas, “the county mowed it up.” It happens. Fortunately, she captured plenty of beautiful shots earlier in the fall.
