It is a native plant from Long Island, New Tork to Michigan, south to Florida and Louisiana and prefers moist areas, meadows, borders of marshes, savannas, damp slopes, wet-mesic prairies, in neutral to slightly acid soil.
Sow seeds in full to partial sun, and in areas with moist to moderately moist soils. Tolerates a combination of heat and humidity and is excellent as a cutflower, plus it attracts butterflies and seed-eaters. A perennial plant in zones 3-10.
Gayfeather can have seed dormancy issues so moist chilling the seed for two to three weeks to break dormancy is recommended.
