White Snakeroot (Ageratina altissima), is an herbaceous perennial that blooms from early autumn until frost. Native to the eastern United States and Canada. Its flowers are an important source of food at the end of the season for bees, moths, flies, and butterflies.
White Snakeroot plants grow to be 2 to 4 feet tall. They prefer shade to partial shade.
Like many plants that grow around us, this is a plant that is poisonous, containing tremetol. If you don’t know the plants in your gardens and in the woods around you, really really well, don’t eat them.
