In early 2019, I looked closely at the peduncles of Hoya thailandica, and I thought I could almost see that tiny buds were trying to form on one of them. I was unsure if it was just wishful thinking, but in another week the beginnings of buds were unmistakable. Only one peduncle out of 12 or so was budding up, but I was ecstatic; now would they make it to term?
At the end of January of 2019, I finally got my wish and the rather large buds began to slowly open!
