Beautiful bright green leaves...no idea what it is
[By way of a disclaimer: we unknowingly bought our house from a landscape architect when the entire 2.5 acres was under 4 feet of snow. We are now approaching our third summer here and are still discovering new plants. It's like a treasure hunt.]
I happened to walk by this today and I have no memory of ever noticing it before. That feels absurd because it has such a gorgeous spring green color that I can't believe I never saw it before.
Anybody have any ideas what it might be?
