Can anyone identify this plant? I evidently bought it 3 years ago, and it has come back every year, but has never blossomed. Last year it grew to about 2 ft tall. This year it is already over 6 ft. I thought it was a columbine, judging from the leaves; but now I know that can't be. There are three of these planted in a square planter and I probably bought them to cover up the electric meter on the side of the house. See photo of the top (which looks like blossom buds but just continues on as another set of leaves) and another photo of the leaves themselves at the base of the plant. A third photo shows the plant from about 8 feet away against the side of the house -- to give you some idea of the size it has grown so far this year -- and it's only May!
