Hoya endauensis is a rare and captivating tropical species native to the Endau-Rompin region of Malaysia, where it grows as an epiphyte in warm, humid rainforests. Cherished by collectors for its unique golden-yellow blooms and leathery foliage, this species is both visually striking and botanically intriguing.
The leaves are medium-sized, thick, and slightly glossy, with a firm texture and a deep green hue. When mature, Hoya endauensis produces umbels of star-shaped flowers that are pale yellow to golden with a contrasting red corona. Each bloom appears waxy and luminous, with a delicate, sweet fragrance that intensifies in the evening. The combination of bold flower colour and tidy foliage gives this plant a refined yet exotic charm.
Compact, easy to manage, and delightfully fragrant, Hoya endauensis is a must-have for collectors who value both form and flower a living example of tropical perfection from the Malaysian jungle.
Thrives in bright, indirect light or gentle filtered sun. A few hours of morning or late-afternoon light will encourage flowering and maintain strong, healthy foliage. Avoid harsh midday sun, which can scorch the leaves, and low light, which may limit bloom production.
Allow the top 34 cm of soil to dry before watering again. Hoya endauensis prefers light, consistent moisture and excellent drainage. Water thoroughly, allowing excess to run off. Overwatering can cause root rot, while extended dryness may lead to leaf shrivelling. In winter, reduce watering frequency slightly.
Temperature: Prefers warmth between 2030C; avoid exposure below 15C.
Humidity: Requires moderate to high humidity (6085%) to thrive. Mist occasionally or use a humidifier to maintain the desired moisture level, especially in dry indoor conditions.
Use a well-draining, airy epiphytic mix, such as orchid bark, perlite, and coco coir or sphagnum moss. This combination ensures both airflow and moisture retention. Terracotta pots are ideal for promoting natural evaporation and preventing overwatering. Repot every 23 years or when the plant becomes root-bound.
Feed every 46 weeks during the growing season (spring and summer) with a diluted, balanced liquid fertiliser or a bloom-boosting formula high in phosphorus. Avoid over-fertilising, as Hoyas prefer light feeding. Suspend fertilisation in autumn and winter when growth slows.
Prune lightly to shape the plant and encourage branching. Do not remove the peduncles (flower spurs) after flowering, as Hoya endauensis reblooms from these spurs each year. Wipe leaves gently with a soft, damp cloth to remove dust and maintain their glossy texture.
A compact, moderate grower with a trailing or climbing habit, typically reaching 4060 cm in length indoors. Once established, the plant produces clusters of up to 1520 flowers per umbel several times a year. Mature specimens bloom freely when given bright light and steady humidity.
Yellow leaves: Overwatering or poor drainage.
Wrinkled leaves: Underwatering or low humidity.
No blooms: Insufficient light or removal of flower spurs.
Pests: Occasionally mealybugs or spider mites; treat promptly with neem oil or insecticidal soap.
Native to the Endau-Rompin National Park in southern Malaysia, Hoya endauensis is an epiphytic vine that thrives on trees in shaded rainforest canopies. It was discovered and named for this biodiverse region, which is home to many unique Hoya species. Its bright golden-yellow flowers with red coronas are among the most distinctive in the genus, making it a highlight of any advanced collection.
This species epitomises the tropical grace of Bornean Hoyas compact, beautifully symmetrical, and richly fragrant. Like all Hoyas, H. endauensis contributes to cleaner indoor air and adds an element of refined exoticism to any growing space.

Toxicity note: Contains mild latex sap that may irritate skin and is toxic if ingested. Keep out of reach of pets and children.
Display Hoya endauensis in a hanging planter or wall-mounted pot, allowing its vines to cascade naturally and its golden flowers to hang elegantly beneath the foliage. For a vivid tropical contrast, pair it with darker Hoyas such as Hoya waymaniae Kapuas or silvery foliage plants like Scindapsus pictus Silver Hero. In greenhouse cabinets or bright bathrooms, its waxy blooms add both colour and fragrance a refined statement of tropical authenticity.
