Christmas flower?

Son number one came through in the flower department again. He got me this plant for Christmas last year from the St. Louis Botanical Gardens. He lost the tag to it and couldn't remember what it was called or even if it bloomed or not. Well, as you can see, it does bloom - beautifully, I might add. But I still don't know what it's called or anything else about it. I'm just calling it my Christmas Flower for now. Any one out there have any clues?

Peace
