My son planted a ton of old expired seeds in a pot, only one plant grew.

We put it in our garden and we assume its some kind of bean plant, but really can't tell.

Any ideas?

Yep, looks like a bean plant to me. You'll be seeing little tiny beans forming pretty soon where the flowers are now.

Well glad its confirmed, but we are trying to find out what kind of bean.

The seed packet would tell you, but sounds like you probably don't have it any more. So if you'll post another picture when the beans get ready to pick, about as thick as a pencil or so, we can take a guess. There are thousands of different kinds of beans.

just thought someone would recognize the leaves or beginning stages of the bean.

Welcome to NGA, @byulasfjazz !

Most beans look pretty similar when they are growing; and, even more definitive than a photo of the "green beans" would be if you could let some pods fully mature (don't pick them off, just leave them on the plant until they turn brown and dry) and then post a photo of the dried bean seeds from the pod. However, there are many varieties that have white seeds, brown seeds, etc.; it would be helpful if you could narrow it down a bit, such as whether it is a bush bean, a pole bean, a bean that is usually used as snap beans or one that is usually used as dried beans, etc. However, since this was apparently just a "hodgepodge" of seeds that were planted, how important is it that you identify this bean variety? Pretty much any ID that we can give you is going to be a guess, I'm afraid.

That looks like a pole bean with the vines looking for more ways to go up. That support there will get quickly over run if that is the case. My pole beans went up over 6 ft and started growing all over each other in a messy mass.

Some bean plants have different colored flowers, so starting out white and getting yellowish before the flowers fall and the beans start to grow is a bit of a help. It narrows it down, but not by much. Like the others have said, the best we can say is that it is some kind of bean. My blue lake pole beans look exactly like that, but many many others do too.
