Awesome! I have a positive ID from the Magnolia folks!!! Thanks to everyone for the input. I never, ever would have thought it was a magnolia. Anyway, I highly recommend getting this tree if you have the chance or inclination. The smell is great.
Your tree is most definitely Magnolia figo (formerly called Michelia figo).
M. figo is native to a wide area of South China including Guangdong,
Guangxi, and Jiangxi. I grows well throughout the southeastern US and the
west coast of California, Oregon, and Washington.
You probably noticed the sweet "candy-banana"- like fragrance of the blooms.
Thank you for your question.
