Winter hardy to USDA Zone 8 (marginally hardy in Zone 7 with protection and mulch) where it is best grown in medium to wet soils in full sun to part shade. Best flowering is in full sun. This plant thrives in moist, fertile, humusy but well-drained soils. It is a versatile plant that tolerates an extremely wide range of growing conditions. It thrives as a marginal water plant and in boggy soils. It also does well in average garden soils with even moisture. Established plants have respectable drought tolerance. Plants also tolerate high heat and humidity. Cut back stems after flowering to encourage new flowers. Plants will spread by rhizomes and self-seeding in the garden, and have escaped gardens and aggressively naturalized in parts of the southeastern U.S. Notwithstanding its value as an excellent flowering plant, this species is currently listed as a Category One invasive species by the Florida Exotic Pest Plant Council (FEPPC) because it has been found to invade natural areas and displace native flora in the State of Florida. Plants are most invasive in moist areas. |
