It kind of looks like mimulus
I think Monkeyflower is correct. The lavendar flower color indicates Mimulus alatus. Check the link below.

I agree with Mimulus, but think you might want to check the comments on the Connecticut Botanical site for information on telling M. ringens and M. alatus apart. I had used it to decide I had M. ringens volunteer here.
I had thought the leaves in your picture were too narrow for either, but some pictures I found on the Internet makes me think it probably is one or the other.
