Snakeroot (Ageratina) is a genus of about 290 annual herbs and rounded shrubs from the Sunflower family (Asteraceae).

These plants grow mainly in the warmer regions of America. A few occur in the cooler regions of eastern United States. Two Mexican species have become a pest in parts of Australia. These plants used to belong to the genus Eupatorium, but have been split off.

The inflorescence consists of many fluffy red or pinkish-white capitula in clusters. These lack the typical ray flowers of the composites.

There are many, much-branched woody stems. The leaves are triangular, serrate and opposite. The petioles are rather long. The leaves are fragrant with a rather nasty musky scent.
