Grasses can be incorporated individually as ornamental or structural elements.
They can also be grouped or massed, or they can serve as the very basis a designed plant community. Native grasses add striking fall color and visual interest well into winter; they provide food, nesting materials and habitat cover for birds; and they serve as host plants for numerous butterfly and moth species, as well.
When converting to a native lawn, you have the opportunity to re-imagine the entire space and make efficient use of the open areas.
