My oldest hoya is dying fast. It is labeled 'Purpurea Fusca', but its leaves have the silver streaks all over it, and the umbel is a big round ball of deep red VERY fragrant red flowers. I am told it is Hawaiian purple,or Red Buttons, etc...but I bought it like 15 years ago, when hoyas were wrongly named frequently. So....can this be red buttones, or another variety? I cant find a red flowered one, that grows very fast and blooms nearly all year,with a big round ball of red fuzzy flowers. That sounds like Red Buttons, except that it grows VERY fast. It is also almost dead now. I have a smaller one that is putting out a new umbel,and will open in a week or so,but I just cant sem to find this purpurea Fusca. Was it just a made up name? Or is it this 'Silver Treak' that I see on EBay...but the flowers are pink,not red. Any ideas???
