Veronicastrum virginicum, or Culver's root, is a species of flowering plant in the plantain family, Plantaginaceae. It is native to the eastern United States and south-eastern Canada. Growing to 200 cm (79 in) tall by 45 cm (18 in) broad, it is an erect herbaceous perennial with slender racemes of white or occasionally pink or purple flowers in summer.

Names and etymology

Other names and variants include Culver's-root, Culverphysic, Culver's physic, black root. The Latin specific epithet virginicum means "of Virginia", referring to a historic definition covering the entire eastern USA and southeastern Canada, (which roughly corresponds to its current distribution). The name "Culver's root" derives from a certain Dr. Culver who was a pioneer physician of the 18th century and used its bitter roots for purgative purposes.

Description

The stems are hairless and usually unbranched. The leaves are serrated and arranged in whorls of 3-7 around the stem. The inflorescence is erect with slender and spike-like racemes to about 9 in (23 cm) long, giving the flower cluster a candelabra-like appearance. The stamens are crowded and protrude in a brush-like fashion perpendicular to the raceme. The corollas are white and are roughly 2mm in length. These plants flower for about a month from mid-June to late August, depending on the latitude.

Distribution and habitat

Veronicastrum virginicum is found from southern Maine to northwest Florida to northern Louisiana up through Minnesota and somewhat north of the Canada–US border. Culver's root is frequently found in wet to wet-mesic prairies and sometimes moist upland sites. It is also found in a good number of prairie or native meadow restorations.
