Question

Plant which grows like a thick mat over the soil and prevents soil erosion

Answer 1

Grasses rank at the top for erosion control because they have spreading mat-like roots that hold soil very well. Alien grasses are also among the worst invasive plants, so choose carefully and favor native species. Many native grasses are attractive and can be easily maintained by occasional mowing.

Purple threeawn (Aristida purpurea) This drought-tolerant Western native is an excellent choice for protecting slopes because of its dense root system. The seed heads are a soft red purple in spring, fading to brown in summer without irrigation.

Sheep's fescue (Festuca ovina) This clumping cool season grass makes a fast, dense cover with interesting texture. Some cultivars make compact clumps, and others are a light shade of blue.
