sideoats grama
Bouteloua curtipendula
Summary 9
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.
Cultivation 10
It is cultivated as an ornamental plant for native plant and drought-tolerantgardens.
Description 10
Sideoats grama is a warm-season grass. The culms (flowering stems) are 30–100 cm (12–39 in) tall, and have alternate leaves that are concentrated at the bottom of the culm. The leaves are light green to blue-green in color, and up to .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}6 mm (1⁄4 in) across.
The flowers bloom in summer and autumn. They consist of compact spikes that hang alternately in a raceme along the top 15 to 25 cm (6 to 10 in) 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 4.5 to 10 mm (3⁄16 to 13⁄32 in) 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.
Distribution and habitat 10
Sideoats grama grows well on mountainous plateaus, rocky slopes, and sandy plains. It is drought- and cold-tolerant and is hardy in USDA hardiness zones 4–9 (average annual minimums of −30 to 25 °F, −34 to −4 °C).
Ecology 10
It provides larval food for the veined ctenucha (Ctenucha venosa).
Uses 10
Sideoats grama is considered a good foraging grass for livestock. It is planted for erosion control.
