I grew some a couple of years ago but just as they were getting ready (dying back and ready for drying) Hurricane Georges struck and wiped me out. The plants literally blew away! I found one 10 inch leaf (they're very distinctive) curled around a strand of barbed wire on my back acreage, but it was all moldy. Really ticked me off, but the several year drought we were having back then was ended by this storm. So, sorta mixed blessing on that!
