Many homeowners use ornamental grasses as accents, screens, and focal points. That is because the plants provide an easier way of adding elegant texture and color to a landscape.
Since these long grass plants grow in large groupings, they can add more privacy to your home. If you want to block unpleasant views or screening areas of your yard from the view of neighbors and passersby, you can use these grasses instead of erecting a wall.
Furthermore, the tallest ornamental grasses act like green or decorative walls and are less confining. You can spread them out to achieve different objectives like providing shade or blocking a view or sunlight in some areas.
Although decorative grasses can add privacy to your home, you have to choose the best type. For example, many homeowners prefer fast-growing ornamental plants because they are more affordable and offer immediate privacy.
But these plants don’t have a long lifespan and can suffer damage during a storm. An alternative would be to select densely growing plants because they will offer solid coverage of your landscape.
