Swamps of black ash, black ash-yellow birch, black ash-red maple, black ash-elm, black ash-alder, black ash-balsam fir-red maple-white cedar, red maple-white pine, tamarack; seepy wet-mesic woods of sugar maple-black ash, sugar maple-basswood-green ash-yellow birch-bur oak, ash-birch-mixed conifers, sedge meadows, fens, and the relict “bogs” of the Driftless Area.
This is a small, delicate species often found on banks, hummocks, sedge tussocks, mossy logs, around seepage areas or springs, and near pools in the aforementioned forests. It seems to be associated with areas with just a little water flowage. This species was once thought to be quite rare in the state but targeted surveys in the early 1990s and from 2007-2009, have shown that it is fairly common, with 66 populations having been discovered. It is widely scattered with many populations having been found in Monroe and Jackson Cos. as well as Marquette, Chippewa, Burnett, and Polk Cos.
