Thalictrum dioicum L.
Ranunculaceae (Buttercup Family)
USDA Symbol: THDI
Early meadow-rue is a graceful, 8-28 in. perennial with long-stalked leaves divided into many delicate, lobed segments. Petal-less flowers have yellow stamens that hang like small tassels. The female tassel-like blossoms are purple and appear on separate plants. Drooping, greenish-white flowers are in long-stalked terminal and axillary clusters on a smooth, leafy stem.
This flower blooms in the early spring, just as the trees are leafing out, which accounts for its common name. The species name alludes to the fact that the male and female flowers are on separate plants, and is derived from the Greek word meaning two households.
