Cassian Dwarf Fountain GrassGrown for its fine textured green leaves that appear in early spring and grow quickly to form a neat clump. In August, khaki colored bottlebrush plumes rise about a foot above foliage and look terrific for 2 3 months. 'Cassian' is said to have the showiest fall color of all the fountain grasses, golden orange tones before turning khaki. Cut back foliage to about 4" in early winter. New foliage reappears in March or April.
