Rhododendron tomentosum (syn. Ledum palustre), commonly known as marsh Labrador tea, northern Labrador tea or wild rosemary, is a flowering plant in the subsection Ledum of the large genus Rhododendron in the family Ericaceae.

Description

It is a low shrub growing to 50 cm (rarely up to 120 cm) tall with evergreen leaves 12–50 mm long and 2–12 mm broad. The flowers are small, with a five-lobed white corolla, and produced several together in a corymb 3–5 cm diameter. They emit strong smell to attract bees and other pollinating insects.

Distribution and habitat

It grows in northern latitudes in North America, Greenland, Canada, and Alaska, in Europe in the northern and central parts, and in Asia south to northern China, Korea and Japan. It grows in peaty soils, shrubby areas, moss and lichen tundra.

Chemical compounds

All parts of the plant contain poisonous terpenes that affect the central nervous system. First symptoms of overdose are dizziness and disturbances in movement, followed by spasms, nausea, and unconsciousness. Among the plant's terpenes is ledol, a cyclic alcohol with deliriant effects, although poisonous in large doses.

Similar species

This species is not to be confused with the traditionally-used one Rhododendron groenlandicum, found throughout Northern North America.
