I loved this Hoya so much that I spent a couple of hours with a cat whisker and a head worn magnifier trying without success to pollinate Hoya sp. Kalimantan SLM-01. It was easy to remove the pollinaria, but impossible for me to insert it into the flowers lock mechanism. I really feel that if you want to successfully pollinate Hoyas, there would have to be an apprenticeship served under someone who has mastered the technique. Attempting to do this from what one can glean on the internet is darned near impossible. I am also wondering if I have the patience for it!
