Hoya Silver Moon is a rare and highly decorative tropical vine known for its lustrous, silver-flecked foliage and clusters of sweetly scented star-shaped blooms. Believed to be a selected form or cultivar within the Hoya pubicalyx group, Silver Moon is loved for its vigorous growth, ease of care, and dazzling, metallic leaf patterning that shimmers under light resembling moonlight on a calm tropical night.
The long, lance-shaped leaves are deep green and densely splashed with silver variegation, creating a captivating marbled effect. When mature, the plant produces umbels of rosy-pink to magenta flowers with a glossy finish and a rich, honeyed fragrance. Each bloom cluster can last up to two weeks, adding colour and charm to the plants already luminous foliage.
Elegant, fast-growing, and effortlessly rewarding, Hoya Silver Moon is a must-have species for both new enthusiasts and seasoned collectors, offering a balance of bold foliage and reliable blooming.
Thrives in bright, indirect light. Strong, filtered sunlight enhances the silver markings and encourages flowering. A few hours of soft morning or late-afternoon sun are ideal, but avoid prolonged harsh midday rays, which can scorch the leaves.
Allow the top 34 cm of soil to dry before watering again. Hoya Silver Moon enjoys light, consistent moisture but is sensitive to overwatering. In winter, water sparingly, as the plants growth slows and it prefers drier conditions.
Temperature: Prefers warm conditions between 2030C; avoid cold drafts and temperatures below 15C.
Humidity: Moderate to high humidity (6080%) helps maintain glossy leaves and abundant blooms. It adapts well to average household humidity but thrives with a humidifier or occasional misting.
Use a loose, airy, and free-draining substrate, such as a mix of orchid bark, perlite, and coco coir, or a dedicated Hoya mix. This ensures proper airflow and prevents root rot. Terracotta pots are ideal for natural drying between waterings. Repot every 23 years in spring to refresh the soil and encourage vigorous growth.
Feed every 46 weeks in spring and summer with a diluted, balanced liquid fertiliser or a formula high in phosphorus to promote flowering. Avoid fertilising in autumn and winter when growth slows.
Trim long vines to shape and encourage fuller growth. Avoid removing the peduncles (flower spurs), as Hoya Silver Moon will rebloom from these each year. Wipe the leaves occasionally with a damp cloth to remove dust and accentuate the silver markings.
A fast-growing, climbing or trailing vine, typically reaching 1.52 metres in length indoors when given support. As it matures, it becomes increasingly floriferous, with each vine producing multiple umbels of fragrant blooms throughout the warmer months.
Yellow leaves: Overwatering or compacted soil.
Dull foliage: Insufficient light.
No flowers: Low light or removal of flower spurs.
Pests: Occasionally mealybugs or spider mites; treat promptly with neem oil or insecticidal soap.
