Genus

Hoya belongs to the family Asclepidaceae, the milkweeds, which consists 350 different genera and more than 3000 species. Most are found in tropical or subtropical areas of the world. A few are grown as house plants, such as Stephanotis floribunda (Madagascar Jasmine), Stapelia, Huernia, Ceropegia - also called Hearts on a string. In North America there are a vast number of asclepiads growing in the wild, such as Asclepias asperula, Asclepias erosa, Asclepias speciosa, Asclepias subulata. Asclepias physocarpa is a beautiful specimen found i South Africa.

Spread

Hoyas are found solely in the south east part of Asia down to the north of Australia. No Hoyas have been found in Tasmania or New Zealand. Some species are tropical and some grow in dry areas, such as Hoya australis subsp. rupicola. Most are, however, tropical and should, if possible, be treated as such.

Sometimes the author of a plant wants to honor an important person or the collector, for example Hoya macgillyvrayi which received it's name in honor of John MacGillivray or Hoya tsangii which was named after the avid collector Peter Tsang.
