Veronicastrum virginicum
Culver's Root
Veronicastrum virginicum, also known as Culvers Root, is tall, upright perennial found growing in wet meadows, woodland edges, and riparian corridors. Blooming between July and August, Veronicastrum virginicum sets out slender flower racemes, each about 8" long, densely packed with tubular white flowers. Culver's root is a very large plant, growing upwards of 4 to 8 ft with a spread of 2 to 4 ft wide. They are slow to establish but spread by seed or by underground rhizomes to form large clumps. When in bloom, Veronicastrum virginicum attracts numerous pollinators to full sun or partial shade gardens. During the winter, their hollow stems act as a habitat for cavity-nesting bees.

When one thinks of a tall, multi-seasonal, centerpiece plants for a garden, one might think of Veronicastrum virginicum. During the growing season, Veronicastrum, also known as Culver’s root, blooms from July through September with panicles of towering, white flowers atop of tall, unbranched stems, usually as tall as 3 to 6 ft tall. During the winter season, their tall panicles dry gracefully, creating strong contrast among winter colors and textures. Better yet, their dried stems have a hollow pith, which can be uti- lized by cavity nesting bee species.
