Design with this plant

Overview

White Snakeroot (Ageratina altissima) is a perennial herb that thrives in partial shade, reaching 3-5 feet in height. Renowned for its late-summer bloom of fluffy white flower clusters, this North American native is excellent for adding texture to shaded garden areas. Preferring moist, well-drained soil, it's a hardy choice that attracts pollinators while being wary around pets due to toxicity. Space plants approximately 18-24 inches apart for a lush display.
