Chamaedaphne calyculata Leatherleaf
General
An early-successional northern bog species, it is responsible for helping to build and extend the bog mat and aids the establishment of other bog species (e.g. pitcher plants, cranberry). This species will grow best in open areas dominated by Sphagnum mosses. It will often dominate in a low overstory until species like black spruce (Picea mariana) and tamarack (Larix laricina) can grow.
