Chamaedaphne
Also called Dwarf Cassandra, Leatherleaves
Chamaedaphne calyculata, known commonly as leatherleaf or cassandra, is a perennial dwarf shrub in the plant family Ericaceae and the only species in the genus Chamaedaphne. It is commonly seen in cold, acidic bogs and forms large, spreading colonies.
Chamaedaphne calyculata has a circumboreal distribution throughout the cool temperate and subarctic regions of the Northern Hemisphere from eastern North America to bogs in Finland and Japan. The species site is mostly restricted to bogs, but also occur in shrubby fens, rock crevices, and pool margins. Leatherleaf naturally forms large clonal colonies, but is very shade-intolerant. Nutrients are low in bogs due to low mineralization, and plants can only acquire nutrients from atmospheric sources.
Leatherleaf is used as a food plant by the larvae of some Lepidoptera species including Coleophora ledi. In ornamental usage, leatherleaf is widely used by florists as a filler green in bouquets and arrangements. Ethnobotanically, the plant has usage as "sun-tea," a drink in which dried or fresh leaves are steeped in cool water in a sunny location. This technique is used to avoid boiling it as a traditional infusion, which carries the danger of releasing andromedotoxin, a common toxin present in plants of the family Ericaceae. Leatherleaf also has limited medicinal use among some Native American tribes as a poultice of leaves for inflammation.
