Is this the American Vetch? I want to add the photos to the DB. We have it growing everywhere around here and it's a really excellent pasture plant that we love.

Its flowering habit looks more like Vicia sativa to me. Something along that line, perhaps?

American vetch has flowers arranged in a raceme. V. sativa (and others) have flowers born singly.

I would say Vicia sativa too, the flowers are in pairs or singly.

I found some plants growing on the roadside a couple of years ago, I had hoped to get seed but the nearby resident decided to poison them and chop everything good down. This year I have bought some seed, it's a very attractive and useful plant.

I should have clarified that singly born flowers can still be in pairs (or multiples of any number). So yes, V. sativa is a good candidate.

Excellent, thank you all so much!
