Eupatorium rugosum

White Snakeroot

White Snakeroot is native to woodland areas. From late summer to frost, it features small, fluffy, bright-white composite flowers arranged in loose, flattened clusters atop smooth stems. Sharp-toothed, lance-shaped dark green leaves are paired along the stems.

Additional Information:
Native Americans reportedly used a potion made from the roots as a remedy for snakebite, hence the common name. Settlers who drank milk from cows that fed on this plant often developed the disease called milk sickness.

Rugosum means wrinkled, in reference to the slightly wrinkled appearance of the leaves. This plant is synonymous with and has in the past been called Ageratina altissima.
