can anyone identify this plant? I have had it for 3+ years. it has never flowered. last year it turned a spectacular red autumn colour (it might have been stressed by being potbound) but most of the time the leaves are green. I have absolutely no recollection of how I came to own it so I can't provide much help in identifying it. Thanks, Paul.

Maybe Heuchera?

Something close to this, perhaps? It changes color from pale green to copper, but there are other similar cultivars

I agree, a heuchera, aka coral bells. We have over 600 listed in our plant database with over 3000 member submitted images

I crop the original picture

is that stem in the red cycles?. it is unclear wether those are stems or just petioles/leaf stalks, if it is stems, it could also be a shrubby entity, just emerging on spring, soon it should be taller.
My guess it could be something like red leaves ninebark

I guess a few closeups of the leaves would help.

I usually bow to Tofi's expertise, but...a ninebark in a flowerpot for 3 years?

I was thinking it looked more "shrub-y" than Heuchera, too. Maybe one of the dwarfer forms.
