Ornamental grasses are members of the grass or sedge families used for garden design and texture instead of sod or forage. Ornamental grasses have blade leaves and are tall and airy, swaying with the breeze. They make a nice backdrop for a garden plot or as a border at the property line.
Sea oats (Uniola paniculata) is part of the Poaeceae/Gramineae, or grass, family. It is a perennial grass, drought resistant, with interesting foliage. Frequently found on sand dunes, its stems reach 2 feet long, with 6-foot stems and 18-inch panicles dropping off them. Sea oats requires full or partial sun, a moist fertile sandy soil, and can be propagated via division of the rhizomes or by seed. Cut sea oats down to the ground in the winter for proper regrowth.

Papyrus stems reach 10 feet tall with featherlike clusters of spikes 5 to 12 inches long. Small flowers bloom at the tips of the spikes. Papyrus requires full sun or partial shade and wet boggy soil. It can be propagated via clump division.
Citronella grass (Cymbopogon nardus) is part of the grass family. It is a fragrant perennial that grows to 6 feet tall. Its cane-like leaves grow to 3 feet long and 1 inch wide.
