|Inflorescence and leaves|
As the thick leaves are heart-shaped, the plant is sometimes named "Lucky-heart". In Europe, it is sold for Saint Valentine's Day.
Hoya kerrii is a climbing plant that can grow up to 4 meters high (around 13 feet). Stems have a diameter of 7 mm. The leaves are 6 cm wide, 5 mm thick. Adult plants show inflorescences of 5 cm diameter and up to 25 flowers. They produce small balls of nectar, coloured red to brown. They smell only faintly or not at all.
A specimen was collected by Arthur Francis George Kerr 1910 in or 1911 in the Doi Suthep mountains west of Chiang Mai (Northern Thailand) at an altitude of 390 m above sea level. It was transplanted to Kew Gardens where it flowered in August 1911, and the species was first described by William Grant Craib from that plant and the wild collections in 1911.
Culture as housing plant
Garden centers sell young plants as a unique leaf a little bit thin heart-shaped planted in a pot. It stays unchanged during many months. Then it grows quickly : one meter by year.
