Range and Habitat in Illinois
Soft Rush is common in southern Illinois, occasional in northern Illinois, and uncommon or absent in the central part of the state (see Distribution Map). For some reason, it has an oddly bifurcated range within the state. In addition to many areas of North America, this rush also occurs in Eurasia. Across its extensive range, many different varieties have been described. Apparently, only var. solutus occurs in Illinois. Habitats include prairie swales, soggy meadows along rivers, sloughs, marshes, seeps, edges of ponds and rivers, ditches, and poorly drained areas of fallow fields. This moderately robust rush can tolerate some degradation of a wetland site if it is not too severe.
