Hoya polyneura is not an easy to grow plant. It roots easily, but goes downhill just as quickly. The leaves turn yellow and fall off. I tried it a few years ago, and gave up on it deciding that it was not going to grow for me. This summer I spotted a nice Exotic Angel potted specimen at our local Lowes and decided to give it another shot. Knock on wood; this plant seems to be holding up really well through the winter, and we shall see if it blooms this summer. Maybe the secret is the EA potting mix; I just don’t know. When it is healthy it really makes a nice basket.
