Found this coming up today. No tag or even a plain marker. I'm pretty good about remembering stuff I put in even if I don't mark it. But this one has me totally stumped!! Now last late summer/early fall I did put a lot of plants in I had gathered from various places so I guess that is why this one is completely a blank for me. I should say ahead of time I appreciate any help, BUT I won't be able to verify possible identities until it gets bigger probably. Unless someone's guess jogs my mind.
The leaves are quite thin and soft. The very center new leaves are light green.
