I had one do this also (there could be more, but one noticed). I was able to dig down a bit and free the end of the scape from the ground. At least maybe it will still bloom, albeit sideways or upside down
I would like to know what causes it also. Like Larry, I think maybe when it was growing it was blocked by something near the surface. I've seen leaves do this a lot, especially as I've been watching seedlings grow and paying attention a little more closely to their development.
