Natural Grasses

Types

• Natural grass, native grass and ornamental grass are synonymous terms that describe true grass species ((Gramineae), sedges (Cyperaceae) and rushes (Juncaceae). Native grass species grown as lawn turf include Buffalo grass and grama grass. Prairie grass such as switch grass (Panicum virgatum) and big bluestem (Andropogon gerardii) are tall species often used in ornamental plantings. Shorter prairie grasses are indigenous to drier western regions. Needle grass (Stipa spartea), and June grass (Koeleria macrantha) grow 2 to 4 feet in height.

Uses

• Natural grass adapts to many garden conditions and landscape designs. They add height, texture, color, movement and sound to the garden. They require little maintenance when used as lawn turf. Native turf grass needs mowing once or twice a year and does not require additional soil amendment. Natural grass also provides habitat and forage food for local wildlife. Gardeners living in drought conditions rely on native grass species to reduce irrigation needs.

Planting

• Natural grass is planted by seed in spring. Local native plant nurseries provide native grass seed mixtures or single species grass seed. Native plant nurseries often maintain a database and online instructions for selection and care of local natural grass plant species. A weed-free seedbed and cultivated soil helps seeds germinate successfully. Most native seed species cannot emerge from deeper than 1/2 to 1 inch of soil. Cover the seedbed lightly and sprinkle frequently until germination.

Ongoing Care

• Many natural grass species tolerate light shade, while others adapt well to full sun conditions. Some perennial grass species provide vivid autumn color and go dormant in winter. Ornamental grass can be cut back in the autumn when a neat garden look is desired. Natural grass does not require the use of pest control products or supplemental soil amendments. Minor pest infestations are controlled by washing the plant with a strong jet stream of water.
