I just found out about this beautiful grass they can grow in Florida called Gulf Muhly, with fantastic pink seed plumes. Unfortunately most sources say its only hardy to Zone 7 (USDA) though I did see one site that put its hardiness up to USDA 5. Does anyone in Zone 5 or 6 grow and overwinter this grass successfully? And if so, can I trade something for its seed? I'd even grow it in a container if I had to!
