Status:

Leatherleaf is a low, colony-forming shrub of peatlands, ranging from subarctic and boreal Alaska and Canada, Newfoundland and Labrador south to Georgia. (It does not occur in Virginia or West Virginia.) Boreal/ice-age relict peatland ponds in the Pitch Pine Barrens community of northern Anne Arundel County (R. Simmons, presentation) are the only stations in Maryland for Leatherleaf. It was historically known from similar communities in Delaware, but not from Maryland’s Eastern Shore, and is considered extirpated on the Delmarva. The presence and abundance of Leatherleaf is a distinguishing feature of these boreal ponds, which are one of Maryland's rarest habitats. For more on Anne Arundel County's boreal wetlands, see William Sipple’s book “Days Afield” (1999).

Relationships:

Host plant for various moth species including Major Datana Moth (Miller et al., 2018).
