I am very sorry that I can't answer your question, but at least I can tell you my experience.

I have regular one and dwarf one. Actually I found the dwarf one is a great bloomer, blooming all the time with great fragrance. The regular one I keep it in a 10 gallon pot, happy like a pie in my hot sunroom. Almost 5 feet tall with 1 inch trunck, great foliage, very compact. But unfortunately no bloom yet. Maybe I ferted with too much ntrogen. I will let you guys know once it's about to flower, going to be a scene in chilly cold Ottawa.
