Ledum groenlandicum of Michigan Flora.
Typically in bogs and conifer swamps, but more widespread northward, in interdunal swales, in mossy conifer forests, on shaded sandy bluffs along Lake Superior, in rock crevices on Isle Royale.
The leaves have long been used to make a tea, in the Great Lakes region as well as elsewhere. Usually reaches the peak of blooming around early to mid-June, later than Kalmia polifolia, with which it often grows; close to Lake Superior, as on Whitefish Point, flowering may peak around the first of July in late seasons and it is a truly glorious sight to see the two species blooming together in great masses. The woolly pubescence on the undersides of the leaves is white when young but turns rusty brown by the second year on the evergreen leaves (or on herbarium specimens). The style persists on the capsule, which is narrowly elliptic and splits from the base along 5 sutures. See Kron & Judd (1990) for a discussion of the generic placement.
