Not ever having seen one, but looking at pictures, I thought this might be fasciata, but Russ says it isn't, so I'm hoping one of you will know what it is. It has been growing fast and with tremendous vigor and was about to burst its plastic pot. It has a pencil-line-thin reddish brown line running around the edge of each leaf, with an equally thin cream-colored line outside that. The leaves are smooth, but not shiny. The longest leaf is about 15", and all the leaves are fairly thin, but stiff. Any help appreciated.
