This video shows us several types of ornamental grass that can be used in landscape projects. Although none of these grasses are appropriate for use in lawns, they are great options for those who are concerned about water conservation. Ricegrass is a bunch grass with long stems and silver heads. It is a cool-season grass and will go dormant in hot weather. Little Bluestem grows quickly in the Spring and is known for its variety of colors including blue, green, and yellow. Giant Sacaton is a great windbreak grass because it can grow to 6 or 8 feet tall with very little water.
