The 'Leather leaf' (''Chamaedaphne calyculata'') is a
shrub in the plant family
Ericaceae and the only species in the genus '''Chamaedaphne'''. It has a wide distribution throughout the cool temperate and subarctic regions of the
Northern Hemisphere.
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, 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.
The name ''Chamaedaphne'' comes from the latin for "ground laurel"; the common name comes from its tough, leather-like leaf.
Leather leaf is used as a food plant by the
larvae of some
Lepidoptera species including ''
Coleophora ledi''.
