At

http://www.flickr.com/photos/raphanus97 are three photos of a plant
that has me stumped. If it weren't for the five pointed petals I'd
guess it was Common Toadflax (Nuttallanthus canadensis) Please educate
me if my photos are lacking or whatever...


It looks to me like Wahlenbergia marginata (Thunb.) de Candolle, in the
family Campanulaceae. Naturalized, introduced from Asia.
