I had one about 12 or so years ago but it didn't survive long under my care. I think I kept it in too much heat and sun. I do have other hoyas and when they set buds, if I move them from one location to another, the buds will usually drop.
Member @tarev successfully grows this beautiful Hoya, perhaps she can offer advice.
