Canada wood-nettle (Laportea canadensis) is a native perennial herbaceous plant in the Urticaceae family. It typically grows 30 to 150 cm tall. Sturdy, upright stems carry large, alternate leaves that are oval to oblong with coarsely toothed margins. The foliage is dark green above and paler beneath. A defining feature is the presence of stinging hairs on both stems and leaves, which can cause irritation on contact. Small greenish flowers appear in drooping clusters in the leaf axils from July to August. The species prefers shaded to semi-shaded habitats such as riparian forests, moist ravines, and cool, shaded forest floors, and it thrives in rich, organic, moist, well-drained soils.
Medicinal and culinary uses
Canada wood-nettle is edible after cooking: young leaves and shoots can be harvested in spring and cooked like leafy greens. They are rich in vitamins and minerals. Traditionally, the leaves were used medicinally to address various ailments. A leaf infusion was sometimes employed as a diuretic and to relieve joint pain. Handle with care, as contact can cause skin irritation.
Ecological roles
Canada wood-nettle plays an important role in moist forest ecosystems. It provides shelter and a food source for many insects, including certain butterfly species whose caterpillars feed on its leaves. Its inconspicuous flowers also attract local pollinators, including bees and hoverflies. Dense root systems help stabilize soils along streams and limit erosion. By supporting biodiversity, Canada wood-nettle contributes to the ecological resilience of forests in Quebec.
Canada wood-nettle seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
