I would add the caution that it goes dormant, rather messily, in late
summer, and that it should be deadheaded both for looks and to
prevent its fairly enthusiastic self-seeding. If I decide to bring it
here, I'll put it behind something that will conceal its decline.

Mature plants are very easy to divide when dormant, and seedlings
flower in their second or third year. Predators do not touch this
plant as far as I've seen.
