About

Setaria faberi, the Japanese bristlegrass, nodding bristle-grass, Chinese foxtail, Chinese millet, giant bristlegrass, giant foxtail or nodding foxtail, is an Asian grass. It is a summer annual, with plants emerging from seeds in the spring, and setting seeds in the late summer or fall.

Giant foxtails prefer compacted soils, high in nitrogen and phosphorus. The plant gains a competitive edge on crops as the soil pH increases.
