Returns Simplified.Hoya carnosa Stardust is a rare and collectable cultivar of the classic Wax Plant (Hoya carnosa), prized for its unusual speckled foliage and fragrant clusters of starry flowers. Native to Asia and Australia, Hoya carnosa is an epiphytic plant that naturally climbs or trails through tropical forests, making it well-suited to hanging baskets, shelves, or trellises indoors.
The Stardust variety features thick, waxy, lance-shaped leaves that are dark green and heavily flecked with tiny silvery-white speckles. These markings resemble a spray of stars scattered across the night sky, giving the plant its name. Its trailing vines can reach over a metre in length, creating a cascading display.
When mature, Hoya carnosa Stardust produces spherical clusters of small, five-pointed flowers. Each bloom is creamy-white with a pink centre, and together they form a ball of waxy, fragrant blossoms that last for weeks. The contrast of silvery-speckled leaves and delicate flowers makes this plant a true gem in any collection.
Thrives in bright, indirect light. Can tolerate medium light but flowering is best with strong, filtered brightness. Avoid harsh direct sun, which can scorch the foliage.
Water when the top 34 cm of soil feels dry. Like most Hoyas, it prefers to dry slightly between waterings. Use room-temperature water and avoid waterlogging, as this may cause root rot. In winter, reduce watering frequency.
Temperature: Ideal range is 1828C. Protect from draughts and cold below 1215C.
Humidity: Prefers moderate to high humidity (50%+). Occasional misting or placement near a humidifier will benefit growth and flowering.
Use a chunky, well-draining epiphytic mix peat-free compost with orchid bark, perlite, and coco coir is perfect. Hoyas like to be slightly root-bound, so repot every 23 years at most.
Feed every 46 weeks in spring and summer with a diluted, high-potassium fertiliser to encourage blooms. Feeding is unnecessary in winter.
Trim long vines to maintain shape. Do not remove the flower spurs (the short stems where blooms form), as Hoyas rebloom from the same sites year after year.
A moderate grower, forming trailing vines that can exceed 1 m. Flowers typically appear when the plant is mature and not over-pruned.
No flowers: Often due to insufficient light, overfeeding with nitrogen, or frequent pruning of spurs.
Yellowing leaves: Overwatering or poor drainage.
Pests: Occasionally mealybugs, aphids, or spider mites.
Hoyas are often called Wax Plants due to their thick, glossy leaves and waxy flowers. Hoya carnosa Stardust is especially prized for its silvery-speckled foliage that resembles a night sky, adding ornamental value even when not in bloom. Its low-maintenance nature makes it suitable for beginners, while its rare variegation appeals to serious collectors.
