Hoya papaschonii is the only Hoya that I am aware of that appears to be self-pollinating so that anyone that wants to try to raise a Hoya from seed should pick up one of these! I think a well grown specimen can make a pretty interesting houseplant, and I am trying to grow a huge one right now. Below is a photo before I cut off all of the seedpods. I have grown so many of these over the years from seed that I have no reason to grow anymore. Also, I am trying to save myself the mess of all of these pods bursting.
