Bermudagrass (Cynodon dactylon) is an aggressive grass that becomes a weed in many Utah cool season turfgrass lawns. As a warm-season grass, it is used for turfs and pastures in warm climates where it stays green in the heat of the summer, but goes brown in the early fall, and stays brown until early the next summer.
