Named after an American physician, Culver’s root is a native American perennial that grows in forests, meadows, and prairies throughout the Midwest. Erica Culver's Root grows to about 4 feet tall with lance-shaped leaves that surround the stems. Dense spikes of pale pink  flowers with darker stamens open from the top down from July to September on strong, upright stems. Smaller, branching lateral spikes create a candelabra-like effect when in full bloom. Easy to grow, it prefers moderate to moist, well-drained soil in full sun. A good background plant in the perennial bed, it is attractive to butterflies.
