More and more gardeners are discovering the value of ornamental grasses. These easy-to-grow perennials add color, movement, texture and winter interest to gardens—and they can solve a lot of garden challenges. Perennial ornamental grasses can fill in bare areas, provide privacy or screening, and add texture along fences and buildings. They can also be grown in containers. Available in different sizes and colors, smaller varieties are often used as accents or in front borders while taller ornamental grasses, like graceful pampas grass, are treasured for their calming effect as they sway in the breeze. Some considerations when buying ornamental grasses are their grow zone, light requirements and mature height and spread.
