Ranked SX (Extirpated) in Ontario and NX nationally in Canada. Globally secure (G5). Not listed under SARA or COSEWIC. The species historically occurred in southernmost Ontario but is now considered extirpated from the province. GBIF specimens from Ottawa (1965, Porsild) are from a small grove on a railroad embankment, likely not a native population.

Ecological Context
Understory tree of rich mesic deciduous forests, stream banks, and limestone bluffs throughout the eastern United States. Favours south-facing slopes with greater light and reduced competition, and is prevalent on calcareous soils derived from limestone. Typically found as scattered individuals or small groups in the understorey of oak-hickory and mixed hardwood forests. Reaches the northern limit of its native range in southern Michigan and southern Ontario; extirpated from Ontario.

Toxicity
⚠️ Moderate Toxicity

Not listed in Cornell poisonous plants database. USDA toxicity rating is None. PFAF notes the plant contains a toxic saponin, but saponins are poorly absorbed by the body, largely pass through without harm, and are broken down by cooking. Saponins are common in many legume family foods. No significant toxicity concern for humans or livestock.

S38 not listed; S11 Toxicity=None; S29 saponin present but poorly absorbed
