Ragweed

This plant is very common and widespread, occurring in every county of Illinois. It can be found in disturbed areas of dry black soil prairies, particularly along the margins near developed areas. This ragweed is not particularly common in high quality prairies, but patches or isolated plants are regularly observed. Other native habitats include hill prairies, gravel prairies, meadows in woodland areas, and the edges of gravelly seeps. In developed areas, Common Ragweed is often observed in cropland, abandoned fields, vacant lots, fence rows, and areas along roadsides and railroads. Occasionally, it appears as a weed in gardens and lawns. This plant thrives in practically any kind of disturbance. It has properties that inhibit the growth and development of neighboring plants.
