Despite the terrible difficulties in bringing this plant to flower, I love Hoya wightii ssp palniensis.  Unlike many Hoyas, it is not at all temperamental; it is a very easy grower, which counts for a lot in my book.  That is why I took the time to transplant it into a 10 inch pot and keep the plant.  The fragrance is among the best in all of the Hoya world if you are lucky enough to flower the plant.
