I have now grown three campanulate flowered Hoyas and find Hoya sp. Indonesia to be the easiest of the three. I wish that this plant had a better name as there are dozens of Hoyas in Indonesia so this name is pretty generic. I can’t recommend this plant more highly if you are lucky enough to find one.
