Oh I love that color!!! I have the carnosa and am rooting some cuttings of the Fish Tail, H. polyneura I got in trade. Are you familiar with Dregea sinensis? I was lucky to get some seeds and have germinated them and they are growing .. slowly though. It's a relative of hoya.
I think I am gonna repot it and see if that helps . It has light pink blooms. I hope I don't lose it. Its almost down to nothing.
What kind of soil is yours in? Maybe thats my problem. Its in plain old store boght miracle grow. and has been for 4 years now.
