This Hoya was a real challenge for me to not only bring into flower, but to grow as well.  I think if you follow my advice and grow this plant in a series of net pots, it is a plant that can be brought into flower in a couple of years when grown in a warm high humidity environment.  If you don’t have such an environment, I think there are better candidates to consider such as good old DS-70.  I am however very happy that I was able to flower this one on two separate occasions.  I rate this Hoya on a degree of difficulty scale with 1 being dead easy and 10 being impossible at a 6.
