Mystery Blossom

Can anyone identify this flower for me? I've been searching and searching for its name, but thus far it remains elusive. I've seen it grow in a state park in southern Oregon, and it also grows outside the Six Mile Pub in Colwood, so I have no idea where its native home is.

Update: I figured it out. They're nasturtiums. I think I'll plant some this summer, as they're useful and edible, as well as pretty. For any interested apartment dwellers, they apparently also do well in hanging baskets!
