Description
Culver’s Root, Veronicastrum virginicum
DEEPOT 2.5″ x 10″
Light: Sun to part-shade
Moisture: Moist to mesic
Soil: Loamy, acidic soil
Height: 3–6 ft
Bloom Season: July–Sept.
Bloom Color: White
Notes: When in bloom, the sturdy unbranched stems of Culver’s Root are topped with clusters of erect, thin, candelabra-like spikes of blossoms. Each spike, up to 8″ long, holds numerous tubular flowers (about ¼” long) that are creamy white. Later, small seeds emerge in large quantities within woody capsules to be dispersed by the wind. Narrowly ovate leaves, up to 6″ long, are arranged in whorls around the stem. The root system has a central taproot as well as underground stems (rhizomes) which enable vegetative reproduction.
This plant is rarely grazed by mammals; but its spikes of flowers produce nectar and pollen in great abundance for butterflies, moths, wasps, and other pollinators and are recognized as having special value for native bees and honey bees. The seeds are too small to interest birds.
Culver’s Root is adaptable/easy to grow in gardens, yet is not overly aggressive. It provides a dramatic show when in mass; or may be mixed with other perennials in borders, meadows, rain gardens or along woodland edges. Preferring moist, acidic, loamy soil; it will tolerate sand and clay. The flowers are lovely in cut arrangements, lasting up to a week. Left standing, Culver’s Root provides interest through winter.
