I've had this for years, and for some time it was being overwhelmed by a parasitic plant that was growing on the same mount. The flower count then was waay lower (2-3) and the blooms were actually bigger which is odd. Since then I have cut away the parasitic plant and treated it with fungicide and insecticide for maintenance. Now it has sent out 14 buds, some of which have opened. I noticed now that they are smaller and the colour is a bit different.
If anyone can even name this one that would be a plus also. It has a very slight perfume.
