Ageratina altissima / White Snakeroot

from $6.00

Toxic to mammals (deer and rabbit resistant).

Fuzzy-looking white flowers brighten up the shadiest of spaces in late summer and fall. Spreading mainly by rhizomes, white snakeroot is a great contender when battling invasive shade plants like goutweed, periwinkle and garlic mustard, but requires space to form a colony in a garden setting, especially in sunnier locations. 

Ecological Importance: An important food source for late season bees and butterflies, including migrating monarchs, white snakeroot is also a host plant for the larvae of the hitched arches moth.

Height: 2 ft

Width: 2 ft (but can form colonies by rhizomes)
