I'm really curious as to what happened to my Phal gersenii before it was shipped to me. I'm fairly confident that it only happened this one time and it was something with the conditions it was grown. I've never had a Phal leaf look like this. The only thing I can thing of is the leaf was being smashed by something as it was growing. The folded up leaf is firm, and I'm sure if forced open, it would break.
