The main difference between my Hoya wightii ssp palniensis and others is that this one was a @#!*&? to bring into flower. I’ve read all over the Internet how this plant is difficult to root , easy to grow, and flowers in a relatively short time. It took me three and a half years with an extremely healthy plant to pull it off. It has a tendency to grow peduncles which never bud up and eventually abort them.
