Vigorous grower that needs little care, other than restraining its takeover of the world.
Cut to the ground in November, and you'll have bright green shoots from March, with a stunning 30" high display of white spires from June through early Sept. OK with 3 hrs + in the sun, and seems very tolerant of sporadic watering, with little nourishment.
Just restrain those roots - spreads as fast as mint.
This was very hard to eradicate from my old garden. Anything that runs underground has to be carefully situated, in my experience. If planted as a mass planting, alone, it would likely be fine, but in a bed, it will swallow its neighbors!
A wonderful trouper of a plant. Reports of its invasiveness are greatly exagerrated. The plant does spread VERY agressively via runners, but it is quite shallow-rooted any easy to pull out when it oversteps its bounds. (I have seen no self-seeding.) A small grouping of two or three plants quickly merges into a lovely small meadow of late-blooming, 2-1/2 ft stalks with flowers that last a month and more. Great for filling large empty areas quickly and thickly. Also a terrific, pretty cut flower for filling out arrangements. Likes always-moist soil. Thrives in full sun to partial shade.
While the flowers and foliage are very interesting, I have had a hard time keeping it under control. It spreads very aggresively via long thick red runners.
