Trying to ID for a friend.
Last pic, back of leaf.
Reminds me of the ornamental pipers - ornatum or crocatum - though not exactly those
TY, I've not heard of those. What about Cissus?
Alternate leaves on Cissus I believe.
Yes, I see that's true, TY VM for pointing that out.
Piper is close, but I can't find any with identical leaf patterning. (But did see a lot of pretty plants I absolutely need!) What a pretty bunch! TY so much for saying that.
If nobody here knows, it's a serious mystery!
