Trientalis borealis Rafinesque. Common name: Northern Starflower, Maystar, Star-of-Seven. Phenology: May-Jun. Habitat: Northern hardwood forests, rich slope forests, often in second-growth areas. Distribution: This northern species, widespread in the mountains of VA, and known from a few locations in n. GA and ne. TN (Chester, Wofford, & Kral 1997), was first located in NC only in 1988 (Dellinger 1989).
ID notes: "The attractive white corollas, usually with 7 petals united only at the very base, are open in the late spring and they drop intact – like fallen stars" (Voss 1996). This species can be recognized by its terminal whorl of leaves (4-10 cm long), the one to several white flowers borne on terminal, slender pedicels, each flower typically with 7 petals (inconspicuously united at the bases), each petal acuminate.
