From my archive of unpublished videos here is a visit with Hoya sp. DS-70 from 2012. It shows two plants; one I received as Hoya burtoniae and the other as DS-70. I believe that they are the same plant. Regardless of what they are, there is probably no easier to obtain, easier to grow, or a Hoya that can give as much joy as Hoya sp. DS-70!
