I’ve only been growing Hoya surisana now for about 4 or 5 months so I don’t have that much to say about its likes and dislikes. I don’t believe at this point that it is a Hoya that I can recommend to beginners and casual collectors, but for serious collectors it is probably a must have. Its very unusual flowers with extra long calyx lobes, makes it worth seeking out. I will report back when I have more experience with its cultivation and subsequent flowerings.
