General: Sunflower family (Asteraceae). Yellow coneflower is a native perennial herb growing from a woody caudex up to one meter or taller. The leaves are pinnantely compound, mostly with five to seven lanceolate segments, with harsh and scurfy surfaces (Bruggen 1976). The disk flowers are usually gray at first becoming brown with age. When the disk heads are crushed, an odor of anise is emitted. Each flower has its own stalk and five to eight yellow, drooping petals arranged in a cone shape.
Distribution: Yellow coneflower ranges from Ontario and New York to Minnesota, South Dakota, and Nebraska, south to Georgia, Arkansas and Oklahoma (Steyermark 1963). For current distribution, please consult the Plant profile page for this species on the PLANTS Web site.

Regularity: Regularly occurring
Regularity: Regularly occurring
This species occurs in prairies, thickets, and borders of woods. It is often found along roadsides and railroad right-of-ways. Yellow coneflower grows best on loam, clay, and sandy soil types that are from medium moisture to dry. It prefers calcareous soils that are neutral pH 6-7, but will grow in sunny locations with well-drained soils, and is often found in wet mesic, mesic and dry mesic sites.
Range and Habitat in Illinois
Propagation by Seed: Ratibida pinnata seeds are best planted in the spring or fall. Generally the seeds does not need any pre-treatment. They can be stratified at 33 to 38ºF for thirty days.

Cultivars, improved and selected materials (and area of origin)
Somewhat available through native plant seed sources within its range. Contact your local Natural Resources Conservation Service (formerly Soil Conservation Service) office for more information. Look in the phone book under ”United States Government.” The Natural Resources Conservation Service will be listed under the subheading “Department of Agriculture.”
Harvesting of seeds should be done from October through November. The cones should be clipped form the stem and placed into a bucket to rub the seeds off the cone to be used for propagation.
Relevance to Humans and Ecosystems
Ethnobotanic: Ratibida pinnata root was used to cure toothache (Fielder 1975).
Landscaping &Wildlife: Yellow coneflower is a strong survivor of former prairies where the majority of the original plants have perished. This is a long live species and is best to plant where there is competition from other plants. The seed heads are eaten by birds in the late fall. The flowers attract several different butterfly species.
Ratibida pinnata is a species of flowering plant in the aster family known by the common names pinnate prairie coneflower, gray-head coneflower, yellow coneflower, and prairie coneflower. It is native to the central and eastern United States and Ontario in Canada.
This species is a perennial herb which can well exceed one meter in height. It has fibrous roots and rhizomes or woody caudices. The rough-haired, glandular leaves are up to 40 centimeters long and are divided into several large lance-shaped or oval lobes. The inflorescences are tall, generally far above the highest leaves. Each flower head contains up to 15 yellow ray florets up to 6 centimeters long. The center of the flower is globular or oval in shape and measures up to 2.5 centimeters long. It is covered in up to 200 or more disc florets which are yellow-green to purplish in color. The disc heads have a scent reminiscent of anise when crushed.
