Sporobolus compositus - Rough Dropseed
Rough Dropseed (Sporobolus compositus) is a perennial prairie tallgrass and is the most robust of all the "dropseed" species with its height. It is often clumped at its base and forms multiple green culms from a crown that are unbranched. Each culm has 4 - 7 alternate leaves that are mostly smooth, and are found along the lower half of the culm. The culm terminates into a spike-like panicle about 4 - 12 inches long that becomes purplish-green during bloom and is mostly hidden by the uppermost sheath when it is young, but becomes more exposed as it matures and turns light tan.

Sporobolus is a genus of about 160 species of grasses that can be found in tropical, sub-tropical, and warm-temperate regions throughout the world. The name means "seed-thrower," referring to its dispersion of seeds, and is derived from the Ancient Greek words "sporos" and "ballein." They are typical prairie or savanna grasses, and make nice additions to native gardens. They have been used in popotillo art or straw mosaics, and some species have been known to be used as a food source by humans.
