Ecology & Natural History
Habitat: Species is distributed on waste grounds, lawns, along roadsides and railroads. ILPIN Notes: Mycorrhizae - endomycorrhizal (from PIN). "Allergenic - yes" from PIN. Species may serve as a tough, satisfactory lawn grass in southern Illinois. Because of its long flowering season, wide geographic distribution, and very light and prolific pollen, Bermuda grass is considered to be the worst hayfever grass in the United States. It has distinct autogenicity from other grasses. For best growth, species should have full sun, slightly acid to neutral soil, regularly applied fertilizer, and close mowing. Stephens, H.A. 1980. Poisonous Plants of the Central United States. Regent Press of Kansas. Lawrence, KA. 165 pp. "Weediness- noxious" from PIN: persistent weed when established. This species often fails to set seed. There are many races, some with little pollen, some with 50 times as much. It is distinguished by leaf color and growth habit. Species is naturalized in U.S. in all but the north-central and northwestern U.S. In Illinois, it is occasional throughout except for the extreme northern counties. Origin is not clear (Wodehouse). Species is spicate, digitate, 1-sided inflorescence. It is the only one species in Illinois. Functional Relationships:
