Labrador Tea
Ledum groenlandicum Oeder
Ericaceae
An erect, free-branching, evergreen shrub.
Height:
Usually less than 1 m.
Twigs:
Densely covered with brown hairs. Branches reddish brown
to gray, often flaky on older parts. Winter buds are rounded with
many overlapping scales.
Leaves:
Alternate, thick and leathery, narrow, oblong with a rounded apex,
1.5-5 cm long and 4-12 mm wide. Upper surface is dull, dark green,
slightly hairy and scaly, deeply veined. Undersurface has distinctive
dense rusty hairs, with a felt-like appearance. Leaves usually crowded
at top of shrub.
Flowers:
Creamy white, five-petals in terminal roundish clusters, 2-5 cm
across. Flower stalks are straight or slightly curved, 5-8 stamens.
Blooms from mid-June to early August.
Fruit:
Slender, dry capsules about 6 mm long, split from base
upwards into five valves. Persist until following year or longer.
Habitat:
Throughout Newfoundland and Labrador* in bogs and fens,
wet an dry heaths, damp and dry woods, and exposed areas.
Leaves may be used for making tea by steeping in
boiling water for 5-10 minutes. If the water is boiled after the
leaves are put in, a harmful alkaloid is released.
* Northern
Labrador Tea (Ledum plaustre L.) is similar in habitat to Ledum
groenlandicum Oeder but is smaller (10-20 cm high). It is found
on dry hills and rocky barrens of Labrador, but not recorded in
insular Newfoundland.
