For Your Garden - March 2021

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.

Blue cohosh grows statewide in moist woods. Flowers are produced in April and May. The flowers are six-parted and are green-yellow to brown. Its fruits are dark-blue berries. The leaves have seven to nine leaflets. A single plant may be one to three feet tall. The flowers attract pollinators, and the fruits are eaten by wildlife, particularly birds.
