Grass Grass is a type of plant with narrow leaves growing from the base. A common kind of grass is used to cover the ground in places such as lawns and parks. Grass is usually the color/colour ‘green’. Grasses are monocotyledon herbaceous plants. The grasses include the "grass" of the family Poaceae. This family is also called Gramineae. The family also include some of the sedges (Cyperaceae) and the rushes (Juncaceae).[1] These three families are not closely related but all of them belong to clades in the order Poales. They are similar adaptations to a common life-style.
