Distribution in Missouri

Scattered nearly statewide, but uncommon or absent from the northwestern quarter.

Human connections

The names feverfew and wild quinine indicate that the plant was used medicinally. Some Native American tribes made a poultice of the leaves to use for treating burns. Apparently the plant was also used as a diuretic. Today people plant it as part of a prairie restoration or native wildflower garden.

Ecosystem connections

Insects visit the flowers for pollen and nectar. This plant is rarely eaten by mammals because of its coarse texture and bitter-tasting chemicals in the leaves.
