Giant Foxtail - Setaria magna
Family: Poaceae

THIS PAGE IS UNDER CONSTRUCTION.

Description

Giant foxtail is a coarse annual, 2 to 4 m tall. The stem is as much as 2 cm across basally and often has conspicuous prop roots from the lower nodes. The leaf blades are up to 5 dm long, 3 to 5 cm wide, and rough on both surfaces and the edges. Ligules are membranous and hairy, about 3 mm long. Leaf sheaths are glabrous. The inflorescence is a dense cylindrical panicle, 2 to 3 dm long and 3 to 4 cm broad, often nodding. The bristle below each spikelet is longer than the spikelet.

Interesting facts

This species grows in shallow water of both fresh and brackish marshes, bayous, ditches, shores and moist fallow fields. The plants reproduce from seeds and can form large colonies.

Large populations exclude native vegetation.
