Veronicastrum virginicum. Native to Lucas County black dirt prairies ranging from moist to mesic and some open woodland areas. Unbranched stalks 2-4 feet in height with whorls of toothed leaves at each node, tiny white tubular flowers in spikes, usually several atop each stalk creating a candelabra-like effect. Blooms early July to early August.
Perhaps named for a Dr. Culver who utilized its bitter roots, widely recognized for their medicinal value, in treating liver disorders and constipation (do not try this yourself!). Only occasionally seen; does not grow as a rule in disturbed areas.
