Sweet Coneflower (Rudbeckia subtomentosa)

$5.00

Sweet Coneflower has a very high value to pollinators. Its bright yellow flowers are visited by numerous bees, moths, butterflies, and skippers (illinoiswildflowers.info), and it is the host plant to a whopping 30 different specialist bees (Johnson and Colla, 2023)!! Sweet Coneflower is a host plant for the Silvery Checkerspot and 19 other species of butterflies and moths in our area (nwf.org), including the threatened Gorgone checkerspot (Butterflies and Moths of North America).  It is presumed extirpated (legally 'threatened' if rediscovered) in Michigan, so while you may not be preserving the plant that was once here, you are creating habitat for all of the species that need it for survival (mnfi.anr.msu.edu). It is a great plant to have in the landscape.
