Friday Flora Friend or Foe Edition

A vetch.  Ugly name, pretty flower.

I know not what kind of vetch this is.  I used to think of all vetches as evil--exotic invasive species brought over from Europe, and displacing the lovely native flora of California.  I now know that there are lots of native vetch species, some of which are endangered.  There are at least two vetch species on our property; the one I'm not showing a picture of is probably Vicia sativa, the horrible invasive thing.  This one?  I don't know.  I suppose I could ask it...

"Are you a good vetch, or a bad vetch?"
