White snakeroot (Ageratina altissima) Plants

In September and October, the broad, dark green upright stems of this species are topped with bright-white clusters of small flowers attracting fall pollinators. A prolific self-sower; cut back after bloom in a small garden. This is an excellent species to plant after invasive species have been removed in a woodland.

*Please note: When ingested, white snakeroot is toxic to humans, livestock, and other mammals, studies have shown that livestock need to consume a high and sustained dose (1-2% of their body weight over several days) to reach toxicity. If you have pets that tend to eat plants in your yard and garden, consider if and where you might plant this species.*
