DescriptionLabrador tea is a common ericaceous shrub of northern bogs and cool, moist peatlands. It is a many-branched, low to medium (1 -- 3 1/2') shrub noted for its spicy fragrance and rust-colored, woolly hairs on its branchlets and the undersides of its leaves. Although Labrador tea is considered an evergreen, the leaves do not last longer than two growing seasons. Leaves were brewed for tea or medicinal tonic by native and other settlers; however, the leaves contain acetylandromedon which can be toxic, except in very small quantities.
