Green Bristle Grass
Setaria viridisAlso known as Green Foxtail, Wild Foxtail Millet, Green Bristlegrass
Green bristle grass produces soft, cylindrical flowering spikes that closely resemble fluffy green fox tails. Native to Eurasia, this resilient summer annual quickly colonizes disturbed soil, urban pavement cracks, and agricultural fields worldwide. It serves as the wild progenitor of cultivated foxtail millet, producing abundant seeds that sustain wild granivorous birds throughout late summer and autumn.
