Natural History

An introduced, cool-season, shallow-rooted annual grass. It begins its growth just as warm-season grasses go dormant and makes most of its growth in early spring while there is little competition. Its common name was given to it by ranchers because it matures as summer grasses are beginning to grow and is sometimes the only green, palatable grass available at this time of year. Due to its short life cycle it is not really valuable as a forage grass.

Habitat

Waste places and roadsides.
