Western Labrador Tea
Rhododendron columbianum
About Western Labrador Tea (Rhododendron columbianum) 0 Nurseries Carry This Plant Rhododendron neoglandulosum (formerly Ledum glandulosum) is a species of rhododendron known by the common names western Labrador tea and trapper's tea. It is a common shrub of western North America from British Columbia to California to Colorado, where it grows in moist areas such as bogs and marshes. This is an erect evergreen shrub exceeding a meter in maximum height with hairless bark along the stem and hairy or nonhairy hairs on the newer twigs. The leathery leaves are oval-shaped and up to about 3.5 centimeters long. They are fuzzy and hairy on the undersides. The flower clusters appear at the ends of branches. They are racemes of small white to cream or yellowish flowers with five rounded petals and 8 to 10 protruding stamens. The fruit is a capsule containing winged seeds. A number of Native American peoples boiled the leaves of this shrub to make tea.
