White Snakeroot is in full bloom right now in the woodlands and woodland edges. A very common native perennial in our area, it is one of the first plants to emerge in a disturbed site. I've also seen it brightening darker woodlands that are mature and fairly undisturbed.
Formerly in the Joe Pye and Boneset genus Eupatorium, a recent reclassification of many plants in this genus has placed White Snakeroot in the Ageratina genus.
Very similar in appearance to Boneset (Eupatorium perfoliatum), the leaves being the distinguishing feature to tell the two apart. White Snakeroot leaves have stalks, and are rounder in shape, Boneset has stalkless lance shaped leaves.
If you have dry, poor soils in shade, White Snakeroot is a good candidate to try. It flowers from August into early October in our area, providing much needed color in late fall in woodlands.
White Snakeroot is native to northeastern North America. See map below for range.
