This plant is native to Asia and eastern and western North America. It grows in moist wooded areas and other habitat. It is a rhizomatous perennial herb producing an erect stem up to 1.5 meters in maximum height. The large leaf has a palmate blade up to 30 or 40 centimeters wide with deeply divided, pointed, toothed lobes. The blade is borne on a long, slender petiole which may measure up to 45 centimeters long. The leaf is green, darker on top and paler underneath. The inflorescence is a panicle with several clusters of flowers on branches. The flower has no petals and is mostly made up of many long, white stamens each up to a centimeter long. At the center is a spherical cluster of green pistils. This develops into a spherical cluster of green fruits.

The plant contains protoanemonin, which may cause blistering or skin irritation.
