DescriptionGrowing in dense thickets, leatherleaf is often the dominant shrub of open areas in bogs and acidic peatlands. A profusely branched, low to medium (1 -- 3 1/2' (sometimes to 5')) ericaceous shrub, it forms the framework upon which Sphagnum mosses build floating mats. Leatherleaf is easily recognized by its alternate branchlets that spread nearly horizontally from a main vertical branch; the leaves get progressively smaller toward the tip of the branchlet. Considered an evergreen, leatherleaf does retain most of its leaves during the winter. However, the leaves fall off by the end of the second growing season.
