I’ve heard rumors that experienced growers are treating Hoya papaschonii as an annual as it is not a long lived plant.  It sets seedpods so easily that the seed can be continually sown to keep the plant going.  I have no clue what pollinated the flowers in my grow tent as I have not seen even a fungus gnat inside???  More studies need to be done on what is a very strange plant indeed!
