Rhizomes survive considerable dehydration and extended periods of drought, but not prolonged periods of freezing temperatures or exposure to sun. Rhizome and stolon fragments readily generate new plants. 2 mm long, arranged in 2 overlapping rows along one side of each branch , consist of 1 fertile floret and 1 reduced, sterile floret. 1.5 mm long, 1-veined, often purplish. Palea keel glabrous.
Spikelets detach from above the glumes.
Disturbed sites, gardens, agronomic crops, orchards, turf, landscaped and forestry areas. Grows in areas that are irrigated or receive some warm season moisture and on most soil types. Tolerates acidic, alkaline, or saline conditions or limited flooding. Grows poorly in shade. Rhizome and stolon fragments disperse with landscaping and agricultural activities, and soil movement.
