I must have planted this a couple years ago, forgot where it was, now it's al over. The flowers are long & thin, three lobed leaves, I'm positive it is in the sweetpea family but these flowers do not look like apios americana. Any help in identifying this would be appreciated. It is now forming short seedpods with a few seeds in each. Thanks.

Do you have a photo?

I found out it is Hog Peanut which is very invasive, so we are going eradicate it...............if we can. sorry to take so long in answering this. Judy.\
