Most ornamental grasses can be grown alone or with annual and perennial flowers. Ornamental grasses add late summer and early fall color to the garden. They also lend sound to the garden, their plumes and leaves rustling as the wind whistles through them. Plant them where the sun's rays can cause their foliage and plumes to shimmer in the light. Grow grasses in containers.
Grasses are great for dry soil.
They rarely need fertilizer and extra water. Most are disease and pest free. Space plants for good air circulation to avoid possibility of foliage problems. Cut grasses back to almost ground level before they begin growing in spring. Divide warm-season perennial grasses in early spring once new growth starts.
