Hoya Spartioides Large

Borneo-born Hoya spartioides was first identified in the 1800s. It is a very peculiar plant that only has peduncles and hardly ever, if ever, produces leaves that last more than a few days. According to what I’ve read online, they are native to severe, arid environments. This information does not match how I take care of my plant. The lovely flowers only bloom for one day.
