Named after an American physician, Culver’s root is a native American
perennial that grows in forests, meadows, and prairies throughout the
Midwest. Fascination Culver's root grows to about 5 feet tall with
lance-shaped leaves that surround the stems. Dense spikes of tiny lavender flowers open from the top down from June to August 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.

In an
evaluation of various Culver's root varieties conducted at the Chicago
Botanic Garden, Fascination was rated as an excellent choice for local garden
conditions.
