there are no flowers or fruit...it was here when I moved in and has been cultivated in 3 spots...I think

Probably grapevine.

I wish I knew it was a grapevine. I will see if it grows fruit or is just ornamental. I was worried that it was kudzu

Redwards!
Grapevine! If it's wild grapevine, which is where my city got its name from, you really only get the vine. It's not very popular here. I am sorry I do not know about cultivated varieties, or how to tell the differences. May you be blessed with some good advice here and a wonderful week-end!

Thanks. I will keep an eye on it and hope it does not take over

It reminds me a bit of Porcelain Berry vine which is in the grape (Vitaceae) family:
Porcelain Berry (Ampelopsis heterophylla)

It does look a bit like that. I like it. But don't want an invasive wild thing growing everywhere. I will keep an eye out on it

If it looks like planted for a reason (cultivated) then its probably a fruiting one. Did you check well? Maybe you can find some grapes on it.
As far as i know ( dad got a large vineyard) you need to prune it hard. Flowers appear on new shoots in spring???

Might have to wait till next year. I will see what to do for a grape vine and go from there

Flowers on most grape vines are pretty small and the grapes would be tiny right now, too. Wait a month or two, and see what develops.

I have a similar grape vine growing wild in several places. I have not identified mine but I call it Pigeon Grape for now.
If the plants in your yard had been cultivated in three places there would be a support structure for the grape vines to climb. I would venture a guess that if there is no support structure that the vines are most likely a "gift from the birds". The image you posted looks like a very healthy plant; it might be fun to encourage it to grow and see what it bears.

To me, it looks like muscadine.
But if it appears deliberately cultivated, it may be scuppernong, which is closely related to our wild muscadine.

If you see small berries, and they do not hide, and they are very pretty, first light green then as they ripen, the colors change from light green to cream, brownish, pink, blue, and purple, very beautiful, that was why somebody imported the vines into US. Get them all out ASAP----or they will cover everything. That is what happened to me. My neighbor in the back used to have grapes, so I thought they were grapes, and then I forgot, and I also neglected my back yard, was concentrating to get the bindweeds and Bermuda grass in the front yard. After several years, I discovered that they had covered everything and every where. So please keep watching- The main vine is about as thick as your pinky, then from there are long, VERY LONG branches that are thin. The thin ones pull fairly easily, but the fat branches are very hard. And they climb high, reached and climbed my neighbors branches of the crepe myrtle tree branches over my property, climbed that high---and hard to pull---




Thankfully most of them are gone now. By doing it I discovered the HOW to do it---working with a Florian lopper and my favorite sharp small pruner and exercising your arms' strength! and also make sure I was on level ground to stay on my feet so that I do not fall. Here is info from the Virginia Nature Plant Society: NOTICE that the leaves have different forms.

Definitely not kudzu.

Right! In six years Kudzu would have swallowed everything - us included!
