Labrador tea is a common name for several closely related evergreen shrubs in the genus Rhododendron, especially Rhododendron groenlandicum and Rhododendron tomentosum. These plants grow in cold, wet, acidic habitats across northern North America and Eurasia, and their leaves have long been used to make an herbal beverage by Indigenous peoples and settlers. The common name also refers to the tea prepared from the leaves.
Taxonomy
Labrador tea plants were formerly classified in the genus Ledum, but are now generally treated as part of Rhododendron. The name is applied to more than one species, with Rhododendron groenlandicum and Rhododendron tomentosum among the best known.
Description
These are low-growing evergreen shrubs with aromatic, leathery leaves and small white flowers. They are typically found in cold wetland environments such as bogs, muskeg, and peatlands.
Distribution and habitat
Labrador tea species occur across northern North America, including much of Canada, and some related species extend into Greenland and Eurasia. They are associated with acidic, waterlogged soils and other harsh subarctic or boreal habitats.
Uses
The leaves have been brewed as an herbal tea for generations, especially in Indigenous communities. The plant has also been used in folk medicine, although caution is advised because some sources report toxic compounds in the leaves.
Key facts
- Labrador tea is not a single species, but a common name for several closely related shrubs.
- The plants belong to the heath family, Ericaceae, and are now placed in Rhododendron.
- They are adapted to cold, acidic, nutrient-poor wetlands.
- The leaves have been used traditionally to make tea and medicinal infusions.
- Some sources note that concentrated preparations may be harmful because the plants contain potentially toxic compounds.
Labrador tea is strongly associated with northern Canada, where it is part of Indigenous plant knowledge, regional food traditions, and boreal and subarctic ecosystems from Labrador and Québec to the Northwest Territories and beyond.
