Ecological Context
Inhabits moist to wet floodplains, riparian forests, streambanks, and swamp margins across the Mixed Wood Shield and St. Lawrence Lowlands. Typically found in partially shaded bottomland forests and moist meadows near watercourses. In the Outaouais, found along river shores and wet forested areas. Tolerates a wide range of soil textures and pH conditions, including calcareous seeps.

Notes
Exceptionally juglone-tolerant, making it one of few tall perennials suitable for planting under black walnut. Thrives in moist woodland edge and riparian guild plantings alongside other moisture-loving natives. Provides tall late-summer structure in the shrub layer where few native forbs reach. May spread aggressively by rhizomes in ideal conditions and is best suited to large-scale naturalistic plantings rather than small garden beds.

S3 juglone tolerant; S29 can be invasive; S10 may spread aggressively; S4 only appropriate for large sites

A compound infusion of the root was also applied externally to the chest and legs of horses as a stimulant.

Foraging Notes
Young shoots and leaves were an important wild green for the Cherokee, who called the plant 'sochan.' Leaves and stems were boiled, fried with fat, or parboiled and rinsed, then cooked in hot grease. Young stems were also eaten raw like celery. Leaves were preserved by drying, freezing, or canning for winter use. The San Felipe also ate young stems like celery. Some caution advised as the plant is reputed to be toxic to livestock.

S28 8 Cherokee food uses + 1 San Felipe use; S29 edible young stems, cooked for good health

Toxicity
⚠️ Moderate Toxicity

USDA lists toxicity as None for humans. Cornell Poisonous Plants database does not list this species. However, PFAF and OWSL note the plant is reputed to be poisonous to cattle, sheep, and pigs.
