Bob, what you have could be phragmites and not a true cane like the Arundaneria genera, the 3 native canes of the US, A. gigantia(river cane), A. tecta(switch cane) and A. appalachiana(hill cane). These native canes grow in the south and southeastern US with A. appalachiana(hill cane) only in the southern Appalachian Mountains.
