Sporobolus contractus, commonly known as Spike Dropseed, is a semi-deciduous perennial grass that thrives in arid environments such as deserts and semi-desert grasslands. Its native range extends across the Southwestern United States, including California, and into Northwest Mexico. This grass typically forms dense clumps or tufts with stems that can reach up to 1.2 meters (3.9 feet) in height. The stem bases are robust, surrounded by hairless leaves that contribute to its tufted appearance. The inflorescence is distinctive, being dense, cylindrical, and narrow, resembling a spike with numerous small whitish or grayish spikelets that are not particularly showy but have a subtle beauty.

Spike Dropseed is valued for its drought tolerance and ability to thrive in harsh conditions, making it an excellent choice for xeriscaping and naturalistic plantings in arid regions. It is often used for soil stabilization and restoration projects due to its robust root system. In cultivation, it requires minimal care, thriving in full sun to part shade, with low water needs, and preferring soils with fast drainage. It is not commonly afflicted by diseases or pests, but it can spread if conditions are ideal, potentially becoming invasive in some areas.CC BY-SA 4.0
