Plant ID please

I'm not sure what this is. It has popped up in a shady rather area by a Hawthorne bush for the last three years. It maybe something I planted, or sprung from seed. I thought it was a Dioscoria from a bulbil when I first noticed it, but it doesn't seem to twine. Comes up in mid summer and is herbacious disappearing over winter.
If it is something I planted, it is probably something that would be useful, but not so much if I don't know what it is. I'm thinking something polygonium at the moment - like perennial buckwheat perhaps. Can anyone confrm?

I'd say buckwheat, definitely! Don't know which species, but looks quite a lot like the common buckwheat we planted last year. Except maybe a bit bigger/coarser leaves, especially the second picture.

yep, i’d second a buckwheat of some sort.

Hello, I have done a search on PlantNet and it could be Fagopyrum esculentum.
PlantNet is a plant identification app that works very well.

Thanks Ana, I don't think it is Fagopyrum esculentum - I'm pretty sure it is a herbacious perennial (comes back from the roots year after year) whereas Fagopyrum esculentum is an annual. I do grow that as a green manure/cover crop sometimes.

Fagopyrum/polygonatum keep swapping names, so it could be something quite closely related. Possibly a perennial buckwheat. I have grown Fagopyrum dibotrys but that was somewhere completely different and disappeared - unless I tried moving the roots before it expired but don't remember that. If I planted it is was a few years before it showed above the grass, since I have completely forgotten doing it!

Another vote for buckwheat based on the PictureThis app.

What happened to the flower buds? It would be easier to identify from the flowers. It looks related to Malabar spinach to me.

I'll see if I took any pictures of the flowers. I think they were buckwheat like, but smaller and pinker.

I'm certain it isn't malabar spinach (too cool) does that have cool-temperate relatives?

Oh I do love trying to figure out plants.
I think I know what this is. But I wanted a second opinion.

Please let me know what you think it is.... Thanks

that one’s definitely a chenopodium. in my area i’d call it lambsquarter, Chenopodium album. less sure of species for your area…

thank you.. I though it was goosefoot  I just want to make sure it was edible.

CJ, that looks like a variety of lambs quarters to me. Do the leaves underside have a white powdery appearance? The local to me has a slightly different edge shape.

going back to nancy’s buckwheat, i’ve grown two accessions of perennial buckwheat, including F. dibotrys, and that looks reeeeally similar. maybe you did move some…
