yellow foxglove, Digitalis grandiflora

The common garden foxglove with flowers that are usually purple also escapes to the wild. I have not seen that one wild, but have twice seen yellow/white species, including this nice roadside patch. Yellow foxglove apparently likes to move into areas cleared by humans, and has a rep for that in its native Eurasia. This species contains chemicals that could be used like digitalis, but in small amounts that aren't commercially competitive. Yellow foxglove has been reported from CT, ME, MI, MN, NC, NH, NY, OH, VT, and ON. Houghton Co MI, 7/11/14. Plantain family, Plantaginaceae.
