I have this plant growing in a pot. It bloomed last week with a
yellow blossom similar to winter aconite, but the leaves don't
look like WA. Can anyone ID it for me? It may be an epimedium
of some type.

Maybe lesser celandine.

Ficaria verna, https://garden.org/plants/sear...

Thank you both for your responses. I'll tag it as lesser celendine.

Moved to the Plant ID forum.

Thanks, Sue! See you on the quilting forum.
