An unusual looking Angel Trumpet to start the year off

I'm not sure what the cross is on this Brugmansia because the tag is faded, but it sure does have an unusual bloom form.

The blooms are snow white and larger than average.  It has had four blooms since I first spotted it, and all four have looked the same.  I'm hoping the unusual form is the norm for this seedling, and it doesn't evolve into a more ordinary looking bloom.
I've already incorporated this one into my breeding program.  I'm crossing it with some other flouncy brugmansia that have more color. 

I just know 2013 is going to be a great year for Brugmansia!
