Native plants provide beauty as well as food and shelter for wildlife. Native species are adapted to the Illinois climate. They require little or no watering and are resistant to drought, insects and most diseases. Because they are perennials, you can welcome their presence year after year.

Leaves are very thin and no longer than three inches in length. The flowers are white and appear in clusters at the stem tip. Flowering occurs from May through September. Flowers have an hourglass shape. The fruits are narrow pods, about three inches long.
