Distribution and habitat
It is native to Europe, northern temperate Asia, and North America across Canada and the United States. It grows in riparian environments, woodlands, and other habitats, generally in moist areas.
Each individual leaf is composed of 5 to 7 leaflike leaflets, each of which is up to 16 centimeters long, lance-shaped to narrowly oval, and irregularly serrated along the edges. The leaflets have a strong disagreeable odor when crushed.
The inflorescence is a vaguely cone-shaped panicle of several cymes of flowers blooming from the ends of stem branches. The flower buds are pink when closed, and the open flowers are white, cream, or yellowish. Each flower has small, recurved petals and a star-shaped axis of five white stamens tipped in yellow anthers. The flowers are fragrant and visited by hummingbirds and butterflies.
The fruit is a bright red or sometimes purple drupe containing 3 to 5 seeds.
