At the same time I tried the shortening day length hack on Hoya thomsonii ‘Pink’ I also tried it on Hoya linearis, which is another reliable fall bloomer. I had the exact same results and it also flowered at exactly the same time. I am sure that this process could be successfully used on most fall bloomers. Another one that comes to mind is Hoya nummularioides which only seems to flower in the autumn.
