Couch grass (Elytrigia repens) is a warm-weather perennial grass that thrives in hot and dry climates. It spreads quickly through wiry, creeping rhizomes that form a thick blanket of grass over a particular area. Couch grass is commonly found in Europe and North America in home gardens and along roads or abandoned areas. It does not survive in shady or poorly drained areas.

This tough, durable grass is considered invasive in many home gardens and difficult to eradicate because it resists milder herbicides.

Established Santa Anna couch grass lawns are moderately drought-tolerant and easy to maintain as they have low fertilizer and water requirements.
