Name: Hoya imbricata Decne.
Etymology:
The genus name Hoya was given by Robert Brown in honor of the English gardener Thomas Hoy (c. 1750–1822). The specific epithet imbricata comes from the Latin imbricatus ("overlapping like roof tiles") and describes the characteristic growth form of the leaves, which lie close to the substrate.
First description:
The species was first scientifically described as Hoya imbricata by Joseph Decaisne in 1844.
Origin / Distribution:
Hoya imbricata is native to Southeast Asia and is found in the Philippines, Indonesia, Thailand, Malaysia, and New Guinea. It grows in tropical rainforests.
Location / Habitat:
The species grows epiphytically on tree trunks in warm, humid forests. The flat leaves press closely against the bark, forming a protected cavity between the leaf and the trunk. It prefers high humidity, good air circulation, and bright, filtered light.
Description & Notes:
Hoya imbricata is one of the most extraordinary species in the genus. Its large, round to slightly heart-shaped leaves lie flat on tree trunks or cork boards, forming a natural pocket in which organic material accumulates. This distinctive growth form clearly distinguishes it from almost all other Hoya species. The cream-colored to yellowish flowers appear in spherical umbels and have a finely hairy, waxy surface.

For cultivation, the plant is particularly suitable on cork bark or tree fern boards, where it can develop its typical appressed growth form. An airy environment, high humidity, and regular watering during the growing season promote healthy development. Bright, indirect light and temperatures between 20 and 30 °C correspond to the conditions of its natural habitat.
