The genus hoya, commonly called Wax Plant, is a large group of mostly climbing or trailing vines, or sometimes shrubs native to tropical Asia, the Pacific Islands and Australia. Hoya plants are famous as indoor house plants because they can tolerate very dry conditions. With a little attention, hoyas can give years of enjoyment with their waxy, sometimes fragrant, flowers and their green vining foliage that does well in low light. [Hoya Plant Care Information]
