Culver’s root, Veronicastrum virginicum, is an impressive plant and quite stunning in full bloom. I have this flowering in my home pollinator habitat now and just love it! The flowers are white and resemble an elegant candelabra. It blooms from late June into August. It can reach heights of 3-6 feet tall and adds an amazing vertical element to the landscape. Culver’s root is native to Nebraska and prefers a moist site. It grows well in full sun to part shade. It is an herbaceous perennial that grows in a clump with a rhizome root system, but is not aggressive. Culver’s root has lance-shaped, whorled leaves that are dark green and attractive through the season.
Culver’s root is important to many native pollinators. This plant is visited by leafcutter bees, bumblebees, sweat bees, syrphid flies, red admiral butterflies and soldier beetles.
There are no serious insect or disease problems with Culver’s root. Long flower spikes provide a noticeable accent and impressive vertical height for landscape borders, rain gardens or pollinator habitats.
