Hoya obscura has been around the trade for a very long time, and the odd reason that I have never addressed this species before is that despite its reputation for ease of cultivation, I have never had luck growing it. I have killed it at least 3 times in the past and thought that I had given up on it, but a very nice, Hoya enthusiast from Vermont gave me a cutting with a peduncle on it over the summer, and it has just flowered for me!
