About plant names...

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(!)

Identification: Plants are 4-12" (10-30 cm) tall. Leaves are rounded in shape, split into three lobes near the tips, about 1-1½" (2.5-3.8 cm) around. 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 appear in late spring and are ¹/₁₆-⅛" (3-4.5 mm) long.
