Bogs, conifer swamps (tamarack, spruce, cedar), boggy thickets, marshes, and open swampy or boggy ground; only in acidic soils.
This is the most frequent Eriophorum of acidic soils in southern Michigan. The bristles are typically copper colored to tan. They are white in the rather frequent f. album (A. Gray) Wiegand.
Unilke all our other species, which fruit in spring, this flowers late, in midsummer (typically July), and the fruits, with their cottony bristles, are visible well into the fall.
