Nope, have not grown H. lacunosa. You maybe right about the humidity thing, after all these are tropical plants. My plants outdoors have responded quite well to daily watering and misting. I was at first hesistant to give them frequent watering let alone misting because of their waxy, succulent leaves..I guess they like it that much during hot summer days.
I am just so pleased with H. shooting star...shoots much prominent now..I'll never get tired watching these blooms form
My Hoya kerrii variegata is growing nicely outdoors..continuing its loop trying to grab on anything..poor Sans, the nearest thing it can find
, ..and I saw this growth, looks like a peduncle, hopefully it is!! Okay, I have put a stick for the vine to hold on, after I took this photo.
