Hoya tengchongensis

Hoya tengchongensis is a species in the family Apocynaceae, subfamily Asclepiadoideae. It is native to Tengchong County in Yunnan, China, where it occurs at around 1,300 meters elevation. This plant grows as an epiphytic subshrub in subtropical forest habitats.

Features:

• Creeping / suborbicular small leaves, somewhat similar in habit to Hoya serpens.

• Corolla is adaxially tomentose (i.e. with hairs on the inner surface) and smaller than Hoya serpens (≈ 7 mm vs ~12 mm in diameter in serpens).

• Differences in the corona morphology: in tengchongensis the corona lobes are slightly ascending rather than fully erect as in serpens.

Care Tips:

• Light: Provide bright, indirect light; avoid strong direct sunlight.

• Temperature: Thrives in intermediate to warm conditions (18–25 °C / 64–77 °F). Protect from cold below 10 °C (50 °F).

• Humidity: Prefers moderate to high humidity (50–80%) with good air circulation.

• Watering: Keep the medium slightly moist but allow it to dry a bit between waterings; avoid waterlogging.

• Substrate: Use a well-draining, airy mix (e.g., bark, perlite, coco husk, sphagnum moss).

• Growth habit: Trailing epiphyte—suitable for hanging baskets, mounts, or shallow pots.

• Fertilizer: Apply a diluted, balanced fertilizer during the active growing season.
