Can these be grapes?

Yes, but unless someone planted it there, it is most likely a wild grapevine, very invasive.

Yes, they appear to be.

They look like wild grapevine to me as well.

Porcelain vine...similar to grapes. "Amphelopsis brevipedunculata" if you want to google it. Birds will eat & spread seeds, so can be invasive, National Park Service discourages it.

If you live in a suburb & keep it under control, it could make a nice arbor or fence cover; can grow 15-20 feet.

I have wild grape in my yard along the fences that was not controlled. It even started going under the neighbors siding. It will take over and spreads by roots running under the ground that branches come off of. It is very hard to control. If it has small grapes, it is the wild type. Unless it is in an area you don't care about it will spread every where. It will grow up trees and blanket them and weigh them down. I don't think it is worth having them, they don't make good grapes as they are so small and they are to invasive. They would make a good fence cover if they didn't spread everywhere else in the process.

Yes, a 🍇 vine

A botanist I am not, however, I have been around plants a lot over the years, so with that and with my limited knowledge, it looks like either one of the three Cannabis sativa L., Cannabis indica Lam., or Cannabis ruderalis . I'm so happy to be of assistance in the identification of said plant.

I don't know, but the real question is "Is it safe?" to eat that is or should I destroy it before my children get to it.?

I have the same thing at my house. It is wild grape and the other writers are right; it makes a great fence cover. But, if you don't keep it pruned back in the spring and summer it will cover everything in it's path and then some. It only produces small bunches of small grapes (green) and they are bitter and do not get sweeter as they age. They do dry up and turn purple, but they are ugly to look at at that point and the bunches don't fall off the vine.. I have tasted them and didn't become ill, but I would worry about children ingesting them.

Yes, they are safe to eat. I live in the mountains of WV and was taught they taste better after the first frost, if you can keep birds and turkeys out of them.

The vines make great wreaths.

thank you

I have the same thing running on my fence every year. They look like grape leaves and get thoses little sprouts every season but then the vine mysteriously dies without producing a sing grape. Is it a grapevine?, I don’t think I’ll ever know.

No weed
