Research on ornamental grasses has made us cautious. Sources of information vary widely in the hardiness zone numbers. Many are not hardy in Zone 4 where we live. We have tried several that proved not to be hardy. And we feel we want clump-forming grasses rather than those that spread by rhizomes. We don't have many areas that we want a grass to take over.
MISG Miscanthus sinensis gracillimus - Maiden Grass is a 5'-6' tall clump-forming grass. Slender leaves arch gracefully and curl after frost. Silver plumes appear in fall, providing much winter interest. New growth does not emerge until about the first of May. Space 3'. Spring only.
