Hoya should be grown outdoors but in shade. They are very easy to propagate by cuttings.

The Hoya Pubicalyx 'Royal Hawaiian Purple' (aka Philippine Black) is sometimes mistaken to Hoya Pubicalyx 'Black Dragon' but they are both different.

This plant grows easily in Ft. Lauderdale, Florida. Hoyas like to be as close to sun as possible without being in the sun. They like to be pot bound to bloom. There is a Hoya pubicalyx growing in a tree at Flamingo Gardens in Ft. Lauderdale at least 10-15 feet long. And they have small plants for sale.
