These clump-forming grasses produce large, open, airy inflorescences that can add lightness and motion to the garden. The genus has undergone much revision by botanists, and some of its former members are now known by other names; for one example, see Nassella tenuissima, the highly ornamental Mexican feather grass. Deer don't seem to care for these grasses.
S. gigantea. GIANT FEATHER GRASS. From Spain, Portugal, Morocco. Narrow, arching, evergreen leaves in a clump to 23 ft. tall and slightly wider. Open, airy sheaves of yellowish flowers bloom in summer, forming a broad, shimmering cloud that rises 6 ft. tall and as wide or slightly wider. Little to moderate water.
S. ramosissima (Austrostipa ramosissima). PILLAR OF SMOKE. From Australia. To 67 ft. tall, 3 ft. wide. The erect column of evergreen foliage and blossoms does somewhat resemble a pillar of smoke. Flowering is almost continuous; the airy, light tan inflorescences make up half (or a little more) of the plant's total height. Regular water.
