Help with ID! Is this a native plant?
Help me to identify this plant. I bought it several years ago, but it grows way to fast and way too tall for the spot where I planted it and I really don't like it that much. It seems to thrive in the moist conditions on the North side of the house.
I'd like to know if this is a native plant so I can move it into the boggy forest behind my house. If it is not native, then I will probably just compost it.
