Hoya carnosa ‘Stardust’ is a beautifully variegated and subtly shimmering cultivar of the classic Hoya carnosa, adored for its speckled foliage and easy-growing nature. A member of the Apocynaceae family and native to Southeast Asia, this cultivar stands out for its uniquely “star-dusted” leaves — each one scattered with tiny, silvery flecks that look like constellations against a green sky.

The leaves are thick, waxy, and succulent-like, with a deep green base splashed with fine silver speckles throughout. Some leaves may also show lighter green marbling or faint variegation. The foliage grows densely along firm vines that can trail or climb, giving the plant a full, elegant appearance.

When mature, Hoya carnosa ‘Stardust’ produces clusters of fragrant, star-shaped pink and white flowers. These blooms have a sweet, slightly spicy scent and add to the cultivar’s celestial charm — making it a favourite among Hoya enthusiasts and collectors who appreciate subtle, natural beauty.

Hoya carnosa ‘Stardust’ – Care Guide

Light

Thrives in bright, indirect light. The distinctive silver speckling becomes more pronounced with good light exposure. Can tolerate some gentle morning sun, but avoid harsh midday rays. Medium light is tolerated but may reduce speckling intensity.

Watering

Allow the top 3–5 cm of soil to dry between waterings. As a semi-succulent Hoya, ‘Stardust’ prefers drier conditions and is more tolerant of underwatering than overwatering. Reduce watering in winter.

Temperature and Humidity

• Temperature: Ideal range is 18–27 °C. Avoid cold draughts and temperatures below 12–14 °C.

• Humidity: Average household humidity is fine, though it appreciates moderate humidity (50–70%) for optimal growth and flowering.

Soil and Potting

Use a very airy, fast-draining mix — such as orchid bark, perlite, coco coir, and a small amount of compost. Hoyas do best in lightly root-bound conditions. Repot every 1–2 years, upsizing only slightly.

Feeding

Feed every 3–4 weeks during the growing season with a balanced liquid fertiliser. A bloom-boost fertiliser can be used on mature plants to encourage flowering.

Pruning and Maintenance

Trim lightly to control shape or encourage branching. Remove any old or yellowing leaves. Never remove the spent flower spurs — Hoyas rebloom from them.

Growth and Maturity

A moderate to fast grower that can trail several metres over time. Mature vines produce clusters of fragrant blooms, especially when given strong light and regular feeding.

Common Issues

• Yellow leaves: Overwatering.

• Slow growth: Low light or poor drainage.

• No flowers: Not enough light or overfeeding with nitrogen.

• Pests: Watch for mealybugs and spider mites on leaves and nodes.
