Common couch

Common couch is a perennial grass species native to Europe, Asia, and northwest Africa. It is widely recognized for its extensive and aggressive creeping rhizomes, which allow it to spread rapidly and form dense mats. Because of this robust root system, it is frequently classified as a persistent and difficult weed in agricultural fields and gardens, though it also serves a role in stabilizing soil against erosion. The plant typically grows upright stems with flat, rough-textured leaves and produces slender spikes of flowers during the summer months. Its adaptability enables it to thrive in various soil types and environmental conditions.
