Food source for many types of wildlife

The Illinois Greenbrier (Smilax illinoensis) is a native perennial found throughout the Midwest/Great Lakes Region. In Illinois, it may be found in woodland areas. It reportedly has a faint carrion odor and attracts many types of insects, including moths and flies. Many local mammals and birds eat the plant’s berries and young leaves. This botanic specimen was collected by Floyd A. Swink (1921-2000) from Warrenville, Illinois, in 1952. Swink was a noted local botanist and one of the authors of Plants of the Chicago Region, first published in 1969.
