Related to the rhododendron, Labrador tea is common in wet bogs and lower-latitude forested areas of the tundra biome. The plant adapts its growing style to its specific climate: In the warmer, southern tundra latitudes, it grows straight up to take advantage of the sun, while in the colder, northern latitudes, it grows closer to the ground to avoid the wind and chill.
Labrador tea plants are brewed into a tea that’s believed to reduce blood glucose and improve insulin sensitivity.4
