In landscapes, they are used in difficult sites where little else will grow. They work well with other plants and come in a variety of sizes, shapes, and colors.
Most grasses are easy to grow and quick to bloom, reaching maturity in one or two seasons.
Their height ranges from twelve inches to twenty feet. Fast-spreading running grasses are excellent groundcovers, reducing dust and erosion. Tall grasses can be used to divide the garden into sections or provide a backdrop to borders. They can also be used as hedges or windbreakers. They are undemanding, thriving in salty, alkaline, or acid soil, sun or shade.
