I didn't know they were one and the same. Thank you Greenblogosphere.
Now I have a 5 foot Fragrant Spring tree that I got from Raintree Nursery and two little Chinese Toons that I've grown from seed I guess I'll have a Fragrant Spring grove in a few years. The great thing about them is that their leaves are edible. I say the more edible perennial plants you have the better.
