Anemonella thalictroides), the rue-anemone[2] or windflower,[1] is a herbaceous perennial plant native to woodland in eastern North America.
Thalictrum thalictroides is a hairless plant growing from a cluster of tuberous roots, with upright stems 10 to 30 cm (4 to 12 in) tall that end with flowers.
The showy rounded flowers have 4-15 carpels surrounded by many yellow stamens in the middle, and a cup of 5 to 10 white to pinkish-lilac petal-like sepals.
[3] In late spring, 3 to 4.5 mm (1⁄8 to 3⁄16 in) long, ovoid to fusiform shaped fruits called achenes are released.
[3] The Latin specific epithet thalictroides is in reference to the plant's leaves that look similar to meadow rue.
[6] Originally described as Anemone thalictroides by Linnaeus in 1753, it was transferred to a new, monospecific genus, Anemonella, by Édouard Spach in 1839.
