Butterflyweed is an attractive, native Illinois wildflower found in prairies. Clusters of bright orange flowers have a long blooming period in the summer. True to its name, it is a magnet for butterflies! It needs average to dry soils to perform its best. Butterflyweed can tolerate drought and poor soils once established. Butterflyweed is an important food source for Monarch Butterfly caterpillars, and is a must-have for the butterfly garden. Looks great with Prairie Dropseed and Black-eyed Susan.
