Chamaedaphne

Chamaedaphne is a small genus of flowering plants in the family Ericaceae. The genus contains only one currently recognized species, Chamaedaphne calyculata, commonly known as leatherleaf or wild rosemary. This evergreen shrub is native to boreal and subarctic regions of the Northern Hemisphere, including North America, Europe, and Asia.

Leatherleaf is characterized by its leathery, oval-shaped leaves that are dark green and glossy on top, and covered in small, reddish-brown scales on the underside. It typically grows in acidic, boggy environments such as peat bogs, muskegs, and conifer swamps. The plant is low-growing, rarely exceeding one meter in height, and often forms dense thickets.

The flowers of Chamaedaphne calyculata are small, white, and bell-shaped, appearing in drooping racemes along the branches in late spring or early summer. These flowers are followed by small, dry fruits. Leatherleaf plays an important role in its ecosystem, providing habitat and food for various insects and birds. While not widely cultivated, it is sometimes used in landscaping for its ornamental value in acidic, wet conditions. The genus name Chamaedaphne is derived from Greek words meaning "ground laurel," referring to its low growth habit and leaf appearance.
