''Bouteloua curtipendula'', commonly known as sideoats grama, is a perennial, short prairie grass that is native throughout the temperate and tropical Western Hemisphere, from Canada south to Argentina. The botanical name, species epithet comes from Latin "shortened" and "hanging".


Description

Sideoats grama is a warm-season grass. The culm (botany), culms (flowering stems) are tall, and have alternate leaf, alternate leaves that are concentrated at the bottom of the culm. The leaves are light green to blue-green in color, and up to across. The flowers bloom in summer and autumn. They consist of compact spike (botany), spikes that hang alternately in a raceme along the top of the culm. The spikes often fall to one side of the stem, which gives the plant its name. There are 10–50 spikes per culm, and in each spike there are three to six spikelets, or rarely as many as 10. Each spikelet is long and consists of two glumes and two florets. One of the florets is fertile, and has colorful orange to brownish red anthers and feathery white stigmas during the blooming period, which contrasts with the pale green, pale red, greenish-red, or purple color of the spikes themselves. After blooming, the spikes become straw-colored. The fertile florets produce seeds, and when they are ripe, the spikes fall to the ground.
