Hoya sp. Malang is a rare, locality-specific Hoya species collected from the Malang region of East Java, Indonesia. Like many Hoyas labelled with “sp.” (species), it has yet to be formally described by science but is already a favourite among collectors for its beautiful foliage and richly coloured blooms.

This tropical epiphytic vine produces thick, leathery, oval leaves that are medium to dark green, often with a matte texture and faint silver flecking. The leaf margins are smooth and sometimes slightly lighter, adding depth to the plant’s appearance. Under strong light, leaves may develop a soft bronze or reddish hue.

When mature, Hoya sp. Malang produces umbels of small, star-shaped flowers that are pale pink to peach, with a darker pink corona at the centre. The blossoms are waxy and sweetly fragrant, especially in the evening, making this a delightful plant for both foliage and flower lovers.

Hoya sp. Malang – Care Guide

Light

Thrives in bright, indirect light. A few hours of gentle morning or evening sun encourages flowering and enhances leaf colouring. Avoid harsh midday sunlight, which can cause scorching.

Watering

Water when the top 2–3 cm of soil feels dry. As a semi-succulent, it stores some water in its leaves, so it prefers drying out slightly between waterings. Reduce watering in winter when growth slows.

Temperature and Humidity

• Temperature: Prefers 18–28°C. Protect from draughts and cold below 15°C.

• Humidity: Prefers moderate to high humidity (60–80%), though it will tolerate typical household conditions. High humidity supports vigorous growth and flowering.

Soil and Potting

Use a chunky, free-draining epiphytic mix – orchid bark, perlite, coco husk, and a little peat-free compost. Hoyas like to be slightly root-bound, so repot only every 2–3 years.

Feeding

Feed monthly in spring and summer with a high-potassium fertiliser to promote flowering. Stop feeding during the cooler, dormant months.

Pruning and Maintenance

Prune to shape or control length, and to encourage branching. Do not remove flower peduncles (spurs), as Hoyas rebloom from the same sites year after year.

Growth and Maturity

A moderate grower, developing long trailing or climbing vines up to 1–2 metres indoors. Flowers appear on mature plants given stable light and warmth.

Common Issues

• No flowers: Usually caused by low light or removal of flower spurs.

• Yellowing leaves: Overwatering or poor drainage.

• Leaf shrivelling: Prolonged underwatering.

• Pests: Occasionally mealybugs, thrips, or spider mites.

Background and Benefits

Discovered in the lush forests around Malang in East Java, Hoya sp. Malang is a locality form prized by collectors for its reliability, resilience, and beauty. It combines the easy care of Hoya carnosa-type species with the tropical charm of rarer Indonesian Hoyas, making it a superb addition to any serious Hoya collection.
