Other common names: brown Betty, brown daisy, brown-eyed Susan, coneflower, donkeybead, English bulls' eye, poor-land daisy, yellow daisy, yellow Jerusalem, yellow ox-eye daisy, deer eye (Cherokee)

Blooming time: June to September

Height: 3 ft.

Description: The stem is rough and hairy and usually has no branches below the flower head. The basal leaves are up to 5 inches long and 1 inch across and are often broadest toward their tips. Leaves along the stem are smaller, alternate and have no petiole. Leaves tend to be thick, rough and hairy and may be finely toothed on the edges. Flowers are bright yellow-orange with one or a few per stem. They have 10-20 ray petals that are about an inch long. These petals are arranged around a dome-shaped brown center disk that is usually 1/2 - 3/4 inch across.

Interesting facts: Early settlers used Black-eyed Susan as a stimulant and a diuretic. Leaves were dried and steeped to brew a tea considered to be a kidney stimulant. The Forest Potawatomi prepared a root tea for curing colds. The flowers were boiled with rushes to give them a yellow color. Some people call the Black-eyed Susan a weed, however, it is easily controlled.
