Usually a mesic prairie species, which does not tolerate inundation in
artificial situations. This is not necessarily true in natural areas, as it is
occasionally seen in sedge meadows and wet prairies.
Songbirds eat seed. Deer graze on plant. This species attracts butterflies and
provides a food source for silphium weevil.
Used for upland slope buffer stabilization.
Availability, Establishment, and Maintenance
Propagation is very successful from seed. Because of a tough seed coat, moist,
cold stratification at 33-38o F for 10-60 days is beneficial. After
stratification, sow seeds at a shallow depth (1/2 inch) in the spring.
This is a very slow growing plant above ground. It may only grow one leaf in
the first year and may need some protection.
Direct seeding has been moderately successful.
Deep taproot discourages transplanting, but can be successful if the taproot
is not broken.
