It is a low-growing shrub up to 1.5 m tall. The leaves are alternately arranged on the branch and elliptical to oblong shaped, 3–4 cm long, thick and leathery, with minute scales and lighter coloration on the underside, and an entire or irregularly toothed margin. They are evergreen but often turn red-brown in winter. The flowers are small (5–6 mm long), white, and bell-like, produced in panicles up to 12 cm long. The species site is restricted to bogs, where they naturally form large clonal colonies.
