What is this?

I dunno, the photo reminds me of something but the leaves are entirely wrong.

Consider googleing vines in your zone - look up vines in your zone re the regular thing (I forget, I think of it as usda, and I gather they've adjusted their takes, very recently) and sunset zones., which I am used to, which started with 24, and, to me, aren't enough.) Or, just look re your city.

I have tried that.
Native texas vie
austin common vine
red fruit wild texas
and a few variations. Nada. It is possible it is a transplant.

some kind of Texas globeberry. Apparently the root is the desirable part.

Could be red bryony

I've no clue on this plant..

is it edible?

Some variants are apparently edible, however they are supposed to be bitter beyond usefulness. Native amerinds apparently used the tubers.

Oh lord.

That was the nastiest thing I have eaten in a long time.

beth was spot on with the website.

and it is.........an odd flavor.
You expect bitter with its taste.. but you dont ever QUITE get to bitter because it does not dry out your mouth to -become- bitter..

odd.
What an experience that was.
I am saving the seeds. I like the vine it grows on and is a butterfly/bee friendly plant.

I think it might be a nice vine in a container - I wondered if it might get thick enough to be sort of as a living air conditioner/window screen.

Not really.
The vine is long and thin and the leaves are about the size of my palm.
They are spaced almost 8 inches apart if not more.. and they do not really offer any shade.

Now, that COULD BE due to the soil where I found them. Maybe they can grow thick, but from what I saw they really dont.
They are quite unique looking though. Very interesting. The fruit is spaced perfectly apart and it looks like a line of red christmas lights

That leaf looks like my porcelain vine. It throws berries, but the leaves are not the size you have.
