Comprehensive DescriptionRead full entry
General: Grass Family (Poaceae). It is a persistent, warm-season, perennial, low growing bunchgrass that is found from late summer to fall and reaches a height of 6 feet. It can be distinguished from other warm season grasses by its thick, massive, reddish brown, terminal inflorescence composed of paired silky racemes and its flattened blue green foliage. The culms are erect, 50 to 150 cm tall, compressed, with broad keeled, overlapping lower sheaths and the flat tufts often forming dense, usually glaucous clumps. The sheaths are occasionally villous; blades elongate, 3 to 8 mm wide; inflorescence dense and feathery. The sessile spikelets are 3 to 4 mm long with a straight awn 1 to 1.5 cm long. The fruit/seed period begins in the fall and ends in the winter.
