Hoya micrantha

Hoya micrantha Hook.f. (1883) is a small-flowered hoya of mainland Southeast Asia, from Myanmar and Thailand through Laos and Cambodia to Vietnam, recorded at 125 to 340 m in seasonally dry evergreen forest. It sees a heavy summer monsoon and a cooler, near-dry winter from December to February, and growers should echo that with a mild winter rest.
