Hoya cembra

Hoya cembra was described by Kloppenburg in 1990 from the Philippines. Its two mapped wild records are far apart in climate: one high on a Negros volcano at about 2200 m and one on the Mindoro lowlands. The averaged figures below are therefore intermediate and should be read as a middle path; a grower is safest treating it as an intermediate hoya that tolerates warmth. Rare in cultivation.

Where it grows wild

Epiphytic climber in humid forest; the Negros record points to mossy montane forest and the Mindoro record to lowland forest, so the species may span a wide altitudinal band or one record may be mislocated.

Climate sites at 2231 m (Negros) and 8 m (Mindoro); the species elevation itself is unrecorded. The averaged temperatures are a blend of these extremes.
