Just spent some time at Google and got nowhere. Perhaps you can do better. Read an article a while ago (w/ pictures) about a rare plant that only puts out one leaf. It will put out a 2nd leaf when it is (part of my memory says 150, part says 500) years old, given the correct conditions. How does that sound as a challenge for a house plant? Cannot imagine the going price for a 2 leafed one. Gene
