Hoya, or as we call it, wax ivy, is a genus of evergreen shrubs and lianas from the subfamily Lastaceae, Cuthrus family. Over two hundred species grow in the tropics of South and Southeast Asia, in Polynesia and on the west coast of Australia. The hoya plant prefers sparse woodland, where it finds a tree for support, or rocky slopes. The hoia flower was named by the famous Scottish scientist Brown, author of the ‘Brownian motion’ theory, after his fellow English gardener Thomas Hoy, who devoted his life to breeding tropical plants in the greenhouses belonging to the Duke of Northumberland.
Is a hoya an indoor or outdoor plant?
In nature, an adult plant can reach up to 10 metres in length. The young leafless shoots are purplish-brown in colour but as they mature, they turn green and over time become more woody as leaves and aerial roots emerge. The leaves, fleshy and shiny in a young age, gradually become dull, oval in shape and pointed towards the top. The leaves measure 5-8 cm long and 3-5 cm wide. The hoia flowers are white or pinkish, sterile, star- shaped and arranged in umbrellas on stalked twigs. Each flower is 1-2 cm in diameter, except for the Imperial Hoia, which grows to 8 cm across. The flower has a five-member crown in the centre of the corolla, rising above the petals. The flowers are fragrant and secrete nectar which attracts insects.
