My wife was driving around the school where she teaches one day and saw a pretty amazing plant, and she couldn't wait to show me.
This thing is crazy! It looks fake, but it's the real deal. I knocked on the door to see if they minded us getting a picture of it, and the lady (who turned out to be very nice) gave us the full rundown of it. They picked it up out in West Texas...somewhere...and it has just taken off. It's either Agave or a Century Plant...which look like they are practically the same thing.
At the time of this picture, it was about 18 - 20 feet tall, and should be blooming in a few weeks.
