I have no outside jasmine plants..........the Royal or Star are both inside plants in my zone for sure. I honestly think you have a variety that is not a true jasmine and that is more or less an outside tropical that just will not adjust to the house.
You may find some leaf dropping but nothing like that. The Maid of Orleans Jasmine sometimes drops leaves when it needs water. Otherwise, it just sheds one or two here and there normally, like all plants. I think Cinta hit the nail on the head. If you go by the names of these plants, especially since to many hybrids are showing up, you will drive yourself crazy.
They call so many plants jasmine now because as she said, the smell. Who knows????
I certainly would never say anyone giving advice is wrong. The best we can do is tell you what works for us. Then you need to try it and see what works for you. I agree identifying your plant is the question that needs to be answered. I don't care what they called it....it may be something else. That happens sometimes. I have no Confederates so I can not compare plants. I wish I could be more helpful.
