A low, evergreen shrub with densely hairy twigs and rounded, terminal clusters of white flowers. Rusty Labrador-tea is a small, globular, broadleaf evergreen shrub, to 5 ft. tall, with a picturesque habit created by many erect stems and upright, spreading branches. The smooth, slightly cracked, bark is coppery-orange to reddish-brown. Thick, glossy, narrowly elliptic leaves are aromatic. Upright, bell-shaped flowers comprise flat-topped, terminal clusters.
This northern shrub, typical of acidic, boggy areas, can easily be recognized by the woolly brown undersurfaces of its leaves. In northern Canada, the plant is known as Hudson’s Bay Tea.
