I have this lovely 10' tree in my backyard, and no idea what it is. I believe it may be a tree from China, as my parents remember having trees like this while growing up there. The flowers are extremely fragrant - smelling like a mix of banana, apple, strawberry? Well, let's just say it smells awesome. the flower also has an odd quality of being very delicate. After it's half or fully opened, just touching it will make the petals fall off. If anyone knows the name of this tree, please let me know. Thanks!
