Hoya shooting star is a water hog in my area. I have to grow it in standing water literally. It will make its peduncle when it is cool and will keep it, will rebloom on it several times, but once our temps begin to go very hot and dry outside, even though I grow it indoors, it knows..and will quickly kick the peduncle. But it grows a new one. A pair of new leaves, then a new peduncle at the center. I also have an oversized tray below, to catch the blooms when it starts throwing it out, and to catch the sticky drips. It is not as generous to bloom here, only one umbel at a time, I guess it is our very low humidity that affects it too.
I have seen this plant growing in the wild when I was in the Phils last year, seeing it in bloom on a very high tree limb, a cool mountain region, a huge lake on the backdrop and that area noted for its cool morning mists, and at that time it is cool season too, so it is a humid cool area. So it really made me understand why it seems to prefer being grown cool. Temps there at that time in the 65F to 75F. That is already cool by Phil standards, normal temps there goes up to over 90F plus humidity of 80% to 100%.
