Hoya obovata
IntermediateHoya obovata
An epiphytic Hoya with thick, obovate leaves that are broad and rounded at the tip, the source of its name. Variegated plants are also sold as houseplants.
About
Hoya obovata is an epiphytic member of the dogbane family, native from Indochina, including Thailand and Vietnam, to Sulawesi and the Moluccas in Indonesia. Decaisne described it in 1844. The epithet means 'obovate', describing leaves that are broadest and rounded towards the tip. Its thick, succulent leaves store water, and like other hoyas it dislikes constantly wet roots. Variegated plants are also offered in the houseplant trade, with patterns varying from plant to plant. Other thick-leaved hoyas, such as the heart-leaved Hoya kerrii, are also sold, so check the scientific name on the label. It grows better trained on a support, and a snug pot helps prevent root rot. It is frost-tender, so keep it indoors in winter. In Japan it is sold mainly by specialist nurseries and online, and is not often seen in general garden centres.
