It is a very productive leafy grass, producing between 15-20t/ha dry matter per year on poor soils in Thailand. ![]() It is a perennial and will grow for 10 years or more under good management. Mun River has a high proportion of leaves (80-85%). Switch grass reaches 3 to 6 feet high and 2 to 3 feet wide, while gray sedge is a more compact grass reaching 2 to 3 feet in height with a spread of under 2 feet, and fox sedge is even smaller, with a height of 1 to 3 feet and a spread from 0.5 to 2 feet.Mun River guinea grass is a perennial, tall, leafy grass, similar to Mombasa guinea grass but with broader and softer leaves. Try gray sedge ( Carex grayi, zones 5 to 9) or fox sedge ( Carex vulpinoidea, zones 3 to 7). Prairie cordgrass is even larger with a height and width of 4 to 7 feet.įor a partial sun or more shaded location, consider switch grass ( Panicum virgatum, zones 5 to 9) and some sedges, most of which tolerate wet locations. Big bluestem reaches heights of 4 to 6 feet with a spread of 2 to 3 feet. In a sunny location, try prairie cordgrass ( Spartina pectinata, USDA zones 4 to 9) or big bluestem ( Andropogon gerardii, zones 4 to 9). ![]() Several ornamental grasses thrive along creeks and rivers in woodlands across the country.

Spread new grass seed at a rate of about 80 to 120 pounds per acre, which translates to approximately 1 to 1.4 pounds per 500 square feet.
