Native Habitat and Growth Behavior
This species originates from the rainforests of Borneo, thriving in warm, humid conditions with bright filtered light. In nature, it climbs tree trunks under high humidity (70 %+) and temperatures around 22–30 °C. Indoors, expect growth up to 1–1.5 m when supported by a trellis or moss pole, with leaves showing best form under stable care. Like most Hoyas, it produces latex-rich sap, which can irritate if ingested, so keep away from pets and children.
