I got this tiny hosta in a bargain grab bag online 8 years ago and I'm not sure what it is. I call it "Little".
It grows well and I've divided it several times.
I would think it would be pretty common but I haven't come across anything similar in stores? It's got a very small white edge and it's a darker green. There's a lamium next to it to show how small the leaves are.
Does this look familiar to anyone?
