Culver's Root

Photographed 2 August 2014, Cinder Path prairie remnant between Humeston and Derby, Iowa.

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.
