After years of trying to grow a decent specimen of Hoya aff. Bella PES-03, I finally have done it. I have a large plant with two open sets of flowers and many more peduncles with developing buds. Here is a photo I took yesterday of one set of flowers. More to come as the other buds begin opening. The secret to growing this plant well is apparently in the substrate used. It seems to love large coconut husk chips.
