Berberis canadensis P. Miller. clade: Group Septentrionales. Common name: American Barberry, Allegheny Barberry. Phenology: Apr-May; Sep-Oct. Habitat: Rocky woods, forest openings, glades, usually over mafic rocks (such as diabase) or calcareous rocks (such as limestone), sometimes along fence-rows in sw. VA (presumably spread by birds). Distribution: A broad Southern Appalachian-Ozarkian endemic, not occurring in Canada (the epithet a misnomer): scattered and local in VA, WV, KY, TN, NC, SC, AL, GA, MO, IL, IN, and sc. PA (where apparently now extirpated).
Origin/Endemic status: Native
Other Comments: Along with Berberis vulgaris, Berberis canadensis was subjected to organized eradication programs because of its serving as an alternate host for wheat rust (Puccinia graminis).
