Description

Green foxtail is a weedy and aggressive annual grass native to Eurasia.  It reproduces by seeds and can produce several generations in a single season. It will grow in sun to part shade in most soils, either moist to dry, blooms early and all season and spread quickly. 

The inflorescence is 1-4 inches long and often nods at the tip. The leaves are up to 12 inches long, 1 inch wide and light green. The form is multi-stemmed and spreading. It prefers disturbed areas with poor soil and usually doesn't invade high-quality natural areas as much. Some small mammals and grazing animals will eat this plant.
