Botanical Name

EUPATORIUM rugosum

Plant Common Name

White Snakeroot

General Description

White snakeroot is an upright clumping perennial native to the woodlands of the eastern United States. Its clusters of soft, fluffy, white flower clusters allure bees and butterflies in the late summer to early fall. Foliage is gray-green in color and stems are stiff and brownish red.

White snakeroot requires a rich alkaline soil, with plentiful watering and partial shade. This perennial is great as a cutflower or planting in the back of the border or as a companion to taller ornamental grasses in a meadow-like setting.
