Aerial shoots (15-) 20-80 cm, from caudices on rhizomes, caudices ascending, rhizomes ascending to horizontal. Basal leaves 1-5, simple, deeply divided; petiole 8-22 (-37) cm; leaf-blade orbiculate, 4-10 × 5-15 (-20) cm, base sagittate to nearly truncate, margins serrate and incised on distal 1/3-1/2, apex acuminate, surfaces puberulous (more so abaxially); segments primarily 3, lanceolate to oblanceolate; lateral segments again 1×-lobed or parted (proximal lobe occasionally lobed again); ultimate segments 10-30 (-35) mm wide. Inflorescences 1 (-3+) -flowered, rarely cymes; peduncle puberulous to villous, distally densely villous; involucral-bracts 3 (secondary involucres with 2), remotely subtending flowers, (1-) 2-tiered, simple, ±similar to basal leaves, broadly obtriangular, 3-cleft, 3-10 cm, bases broadly cuneate, connate, margins sharply, irregularly serrate and incised on distal 1/3-1/2, apex acuminate, surfaces puberulous, more so abaxially; segments 3, lanceolate to oblanceolate; lateral segments unlobed or 1×-lobed; ultimate lobes (8-) 10-15 (-20) mm wide. Flowers: sepals (4-) 5 (-6), white, obovate, (8-) 10-20 (-25) × 5-15 mm, hairy or glabrous; stamens 80-100. Heads of achenes spheric to ovoid; pedicel 7.5-11.5 cm. Achenes: body obovoid to ellipsoid, (2.5-) 3-6 × 3.5-6 mm, winged, strigose or glabrate; beak straight, 2-6 mm, strigose, not plumose. 2n=14.


Phenology: Flowering spring–summer (May–Aug).
Habitat: Damp thickets, meadows, wet prairies, lake shores, streamsides, clearings, occasionally swampy areas
Elevation: 200-2800 m

Discussion

Various parts of Anemone canadensis were used medicinally by Native Americans in the treatment of wounds, nasal hemorrhages, eye problems, and sore throats, to counteract witch medicines, and as a general panacea (D. E. Moerman 1986).
