Michigan is at the northeastern edge of the range of this species of mostly wet prairies, savannas, and prairie fens. Our collections are from dry to wet prairies, sedge meadows, and moist open ground at borders of forests.
Showy and sometimes cultivated, collections from Mason and Mecosta Cos. are adventive, as is the Washtenaw Co. record from along a railway. Now sometimes also included in so called prairie plantings, and collected as "Persisting ...about 20 years" in such a planting in Lenawee Co. (not mapped).
See comments under Heliopsis on possible confusion with that genus.
