Concept:A lawn grass must tolerate frequent mowing, trampling, and dry weather while forming a dense, fine turf.
Explanation:Cynodon dactylon, commonly called Bermuda grass, is the most suitable choice for lawns.
It is a low-growing, creeping grass that spreads quickly by stolons and rhizomes.
It forms a thick, fine-textured cover that can be mown short and recovers rapidly.
It has high resistance to drought and can survive heavy foot traffic, which are essential qualities for a lawn.
By contrast,
Andropogon gayanus,
Pennisetum purpureum, and
Panicum maximum are tall, robust forage grasses grown for animal feed, not for lawns.
