Picture would help in identification,
From your description, -- compare with Echinocystis lobata.

add a pic plz

I think I know what you have.
A white Wisteria.. Without more info, could be american or chinese
The pod starts out green and fuzzy, then turns a light brown just before they pop open and the seed is flat on one side slightly raised on the other.Like Old fashioned chocolate drop.
becareful. The seeds are toxic to pets and people.
I pull the pods right before they open.
Hope that helps you.

The seeds are described as plum sized. Wisteria has pods like beans, not plum like fruit. We really need a picture.

Anybody know what this is? Bine with flowers and seed pod, but it's strangling my tree. Last year I battled these as well but they didn't have the flowers or seed pod

I answered on your other post.
