In standing water of floodplain forests, tamarack swamps, white cedar swamps, sedge meadows, ponds, bogs, vernal pools in mesic woods, prairie swales, ditches, also in flowing streams. The distinctive achenes, when present, will readily distinguish this species from R. gmelinii. The former is usually a larger plant in both flower and leaf size. This is a very showy species, mainly found in the southern part of the state but with scattered occurrences northward.
