Alkali Sacaton (Sporobolus airoides) is a moderately fast-growing and moderately long-lived bunchgrass, native to southern and central California. It thrives in a variety of habitats, from coastal areas to foothills, central valley, and desert mountains, typically in locations with slightly more moisture. Its most notable feature is its ability to tolerate alkaline soils, which is reflected in its name. Early settlers viewed it as an indicator of underground water. This grass grows upright to a height of 3 feet, with active growth in spring and summer, producing yellow flowers that bloom in mid-summer. The showy seedheads persist throughout the summer and last for many months. The medium green leaves are deciduous and fall off in winter.
Alkali Sacaton is found in moist, but not saturated, places at elevations ranging from 0 to 6,900 feet. It can tolerate occasional foot traffic, but it should not be considered as a replacement for a lawn in areas that experience regular or heavy foot traffic.
