About plant names...

Bog labrador tea is found in North America, Greenland, Europe, and Asia. The name ”labrador tea” refers to the brewing of a medicinal tea from this herb by the Athabaskans, among others. The Athabaskans are a large group of peoples who occupied northwestern Canada and Alaska prior to the influx of Europeans.

Identification: Plants are low shrubs, which may be erect or lying on the ground, up to 20" (50 cm) in height, and have a sweet resiny scent that attracts pollinators. Wrinkly evergreen leaves are ¾-2" (2-6 cm) × ⅛-½" (3-15 mm), have downward-curled edges, and have unusually dense white to red-brown hairs on their undersides. Flowers are white, fragrant, ⅜-½" (1-1.5 cm) around, with five petals. They occur on rounded corymbs (clusters) 1-1¾" (3-5 cm) in diameter. Each flower has five long white stamens.

Edibility: Poisonous. Skull & Crossbones Although not strongly poisonous, plants contain ledol, which can cause cramps and paralysis.

Medical: Although several indigenous North American peoples brewed medical teas from the leaves, there are conflicting accounts as to the safety of this practice. I wouldn’t drink it.
