Chris,
Well all I can say is Holy Crap!!! I have had one for a very long time (longer than yours) and it is about 50 inches which I thought was some kind of record. It looks like Sansevieria Trifasciata but is never able to give a clear ID. Too many look alikes. That is a real winner. Nice. Are the colors solid or does it have some snake skin pattern on it. Also what is the widest leaf section on it. Can you take a few more pictures closer up?
