At this point, I am as unsure as most of you.  When I first obtained this cutting two years ago, I briefly saw a photo of the plant and was never able to see it again.  I believe the reason is because I am one of the few people in the world without a Facebook account.  If this plant does what it is supposed to do, it will not have the characteristic red corona that all Hoya bella flowers have.  Soon we should have the answer.
