Hoya collina Is Endemic To Biak Island, Indonesia

Being geographically challenged, I had to look this Biak Island online, and apparently it lies on the Western side of New Guinea. There are apparently two different clones of Hoya collina sold and one of them is called Hoya sp. IR26, which gets red leaves in direct sunlight. Mine is definitely not that one as it has been exposed to intense light and the leaves never get red.
