Fens, especially in shrubby areas, and coniferous swamps, often associated with tamarack and cedar, less often with spruce and fir; not tolerant of dense shade, but thriving in open glades, clearings, old roads through peaty ground, etc.; occasionally in other swampy situations (e.g., with red maple) and along calcareous ridges and dunes, with conifers, along the northern shores of Lakes Michigan and Huron.

The hairs of this species, and of C. parviflorum, are irritating to some people, producing a rash resembling poison-ivy.
