pyrethrum daisy, Tanacetum coccineum

It's always fun to find a new flower. This pyrethrum daisy was the first one found wild in Michigan. I'm not sure who spotted it first on that Botany Club outing to Brockway Mountain on the Keweenaw Peninsula. It's a great place for native flowers, and somebody obviously planted a flower garden there long ago. Pyrethrum daisy was one of the holdovers. This species has been used for centuries as an natural insecticide. It works! It has been reported wild from AL, AZ, CA, CO, FL, MA, ME, MI, VT, NB, and ON. Keweenaw Co MI, 7/12/14.
