Synonym(s): Leptandra virginica, Veronica virginica
USDA Symbol: vevi4
The unbranched stems of Culver’s-root grow 2-6 ft. tall and are topped by several spikes of densely-clustered, tiny, white flowers. The total effect is candelabra-like. Narrowly oval, dark-green leaves are arranged in whorls around the stem. The common name was to honour Dr. Culver who prescribed the plant as an effective laxative. (Lamb/Rhynard) Dense, narrow, cylindrical, spike-like clusters of small, white, tubular flowers are at the top of an erect stem over whorled leaves.
The genus name, a combination of Veronica and the suffix astrum (false), describes this plants resemblance to the Veronicas. It is the only species in the genus. It can be grown easily in wildflower gardens. The root contains a powerful emetic and cathartic.
