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.

Nodding onion grows in northeastern Illinois in wooded areas and slopes that are moist. It prefers rocky, sandy or black soil substrates. A plant may reach one to one and one-half feet tall. Leaves and stems arise from an underground bulb. These basal leaves are long and narrow. The stems are leafless. Flowers are produced from July through September. The top of the flower stem is bent downward, and the flowers droop or nod toward the ground. Flower color may be pink, lavender or white. The flowers support a variety of bee pollinator species.
