Sporobolus virginicus grows on sandy beaches, sand dunes, and in saline habitats, primarily along the south-eastern coast, occasionally inland. Its range extends through Mexico and Central America to Peru, Chile, and Brazil. No fruits of this species have been found despite examination of several natural populations and over 200 herbarium specimens.
