I recently contacted Ric Morier to ask about the parentage of Hoya RHM-009 and here is what he had to say:

“It’s one of my crosses. Hoya ridida IML 1424 is the mother. The father is mostly Hoya merrillii.  It has large shiny leaves and grows fast.  I took two blooming plants to my friends garden, and she keeps bees so I think the bees were the pollinators.”

So there you have it.  It was an accidental cross that produced this very handsome plant.
