Veronicastrum virginicum is cultivated as an ornamental for temperate gardens in the Eastern and Central United States around its native range. The flowers are pink and bloom for about a month from mid-June to late August. Most native plant nurseries commonly sell this easy and adaptable perennial. Even some conventional nurseries sell this plant, though it is not common yet in American landscapes and gardens. It is fully hardy down to at least −20 °C (−4 °F), and grows in full sun to part shade and any moist, well-drained soil. It is easy to dig up, divide, and reset like a good number of standard perennials if they get too large or crowded. It stays as an upright clump and does not spread far. Plants rarely need staking; however, older clumps may require this. It can be pruned down in late May or dug up, divided, and reset. This plant does do some self-sowing with its tiny seed.

Veronicastrum virginicum, or Culver's root, is a species of flowering plant that 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 flowers in summer.

This plant has gained the Royal Horticultural Society's Award of Garden Merit.
