One of my sisters gave me a start of this plant from her garden years ago, and I regretted planting it. It was invasive for me and took me years to get rid of every part of it in my garden.

I planted it on the side of our front porch, below the faucet.

Yes, the flowers are beautiful, but if you don't have the space and don't want it to take over, then I'd advise you not to plant it.
