I'm comparing it to my Ann Kulpa for colour but it does not have the obvious ripple of yours. I like whatever it is that you have!
Edited to say, scratch that... Your petioles don't appear to be very channeled, rather more open and wider. Hmmm...sure got me curious.

Thanks, Josephine. I can take a closeup of the petioles if that will help anyone.

It's very tough and yes, ripply. I can't wait to find out what I've got.

Is there some corrugation going on in the leaf at 1:30 position in first pic? Can you do a close-up of it? Someone might recognize it.

It is often very difficult to ID a young plant. So many of them look similar. You may have to wait until you get some mature leaves and flowers to get a better ID. (could take a few years with some slow growers). ;-(

It is a keeper, no matter what it is!!!
