Hoya sp. aff. Bella PES 03

Finally found out the official name of my all white flowered Hoya bella; it is called Hoya sp. aff. Bella PES 03, but other than the name and that it is extremely rare, I have little else to go on at this point.  I will report back when I find out more information.  In the mean time here is the only multi-flower photo that I can locate, and it happens to be mine for now.
