Heat-loving summer annual grass forming tufts, germinating in late spring. Prefers low- organic carbon, yet nutrient-rich, light, warm loamy soils.
Green foxtail [Setaria viridis]
Young leaf is rolled, ovate-pointed (Picture 1), ligules are replaced by a ciliate membrane (Picture 2). Leaves are grass-green, linear-lanceolate, glabrous (hairless), quite broad, gradually narrowing to a point. Without auricle, leaf sheath closed, pubescent (Picture 2). The inflorescence is a 1-2 cm thick pseudo-spike, green to reddish-purple in color (Picture 3). The relatively long bristles do not have any barbs. Each plant produces 400-500 seeds (Picture 4).
