Rue anemone
Rue anemone is native to woodlands in eastern North America. It is a relative of the buttercup family. Thalictrum means “divided leaves;” so does thalictroides(!)
Plants: 4–12″ (10–30 cm) tall.
Leaves: Rounded in shape, split into three lobes near the tips, about 1–1½″ (2.5–3.8 cm) around. Lower leaves have petioles 4–12″ (10–30 cm) long.
Flowers: White to pinkish flowers with yellow stamens appear in groups of 1-6, supported by thin red-brown stems. Each flower has 5-10 petals, and is ¼–1¼″ (8.5–31 mm) around.
Fruits: Achenes appear in late spring and are 1/16–⅛″ (3–4.5 mm) long.
Habitats: Banks and thickets in low-lying deciduous woodlands, at elevations below 984′ (300 m).
