Appearance

The flower of the black-eyed Susan has bright yellow petals and a brownish-black, dome-shaped center. The flowers grow on stems with small, rough hairs and bloom in June to October. The plant's green leaves grow up to six inches in length. Black-eyed susans grow to four feet tall.

Reproduction and Life Cycle

After blooming, the flower’s dome-shaped center matures into a seed head full of small, black seeds. The plant then dies. Wind, animals and other natural disturbances spread the seeds. New seedlings grow in spring.
