Identifying Features

The black-eyed Susan has a singular flower, with 10-20 bright yellow florets circled around a dark brown center. It has rounded to slender leaves that are covered in coarse hair and attached to a hairy stem.

Habitat & Range

Black-eyed Susan can be found in fields, trail-sides, and open areas throughout North America. They are native to eastern and central US, but can also be found growing in many areas of Canada and parts of western US.


Black-eyed Susans are typically an upright plant and can grow up to three feet tall. They are generally tough and can tolerate a wide range of soil and environmental conditions.

Life Cycle

The seeds are sown in fall or early spring and will germinate when the weather warms up. During the months of June-October, the plant produces a flower that will later fade and be replaced by seed heads.
