Veronicastrum virginicum, commonly called Culver’s root, is a large, erect, perennial which occurs in open woods, thickets and moist meadows and prairies. Typically reaches 3-7′ tall when in bloom. Resembles a large veronica, except its lance-shaped leaves are in whorls (3-7 leaves per whorl) on the stems rather than opposite. Dense, slender, 9″ long spikes (racemes) of tiny, tube-like, white to pale blue flowers open from the top down in late spring to early summer atop strong, upright stems. Bloom can extend well into the summer. Smaller, branching, erect, lateral racemes give plant a candelabra-like effect when in full bloom. Root has been used medicinally as a cathartic.
