For Your Garden - October 2017
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.

Purple sneezeweed can be found commonly in southern Illinois. It is present in central and northern Illinois, but the occurrence decreases greatly in those areas. It grows in fields, ditches, wet prairies, pastures and other locations where the soil is moist and somewhat acidic. This member of the aster family may grow to three feet in height. Flower heads are produced at the stem tip from June through September. Each flower head has a brown-purple center of disk flowers surrounded by 8-14 yellow ray flowers. The flowers provide nectar and pollen to a variety of insects.
