It does look similar to a Royal Hawaiian but...

You could put it in the greenhouse and let it decide if it goes dormant or not and when it will wake up.

If you put it in the greenhouse, it will continue to bloom and grow for quite a while -- probably into December. I'd do that. Let it go dormant when it wants to. Then it will likely come out of dormancy very early -- like April. It may not bloom for you next season though.

The flowers are now changing colors! I think it might be Royal Hawaiian by some of the internet pics I've found. I think I'm going to go the "if it aint broke, don't fix it" route and let it go dormant on its own the way it did last year. Then I'll bring it to the greenhouse in March so it will get warmer temperatures and wake up quicker. Thanks!

Well, it's gorgeous whatever it is! Almost looks like a Lani.
