Glib, you were not off Mack ave, north of Saint John's main campus, are you? I've seen some bamboo there and your post made me think of it
JustAnne4. I've read that Arundo Donax is a North American native and it does just fine in very wet (even standing water) locations. The variegated form looks like 10 foot tall corn stalks. It is, however, not very good for cutting canes. I have it and it's a super focal point plant. I just wish it had gotten much bigger (I get 3-4 canes a summer).
