For Your Garden - April 2018
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.

Rough blazing-star is found statewide in black soil prairies and savannas. A single plant may attain a height of up to 30 inches. This member of the aster family has unbranched stems with alternate leaves. The leaves decrease in size from the bottom of the stem to the top. Both the leaves and stem are hairy. Blue-purple to red-pink flowers are produced from July through September. The flowers develop in clusters of 25-40 with the clusters either attached directly to the stem or on a very short stalk. Bracts below the flower heads are rounded with definite, curled margins. Pollinators are attracted to the nectar and pollen from this species.
Classification and taxonomy are based on Mohlenbrock, Robert H. 2014.
