Yes, I found it lovely, but a dry summer in Oklahoma when we had 'hairdryer' southwest winds killed my colony.
It sure looks happy in your garden though.

Does it bloom the first year from seed? It wouldn't survive the winter here, but if it seeds it might work as a nice self-seeding annual like Nicotiana or Verbena bonariensis. I like the foliage.

Never had it reseed. Just runs. And yes it like moist. It blooms rather late so you would mist likely have frost before.
