Hoya finlaysonii ‘Sarawak’ is a striking and highly sought-after tropical vine known for its intricate leaf veining and bold contrast of colours. Originating from the humid forests of Sarawak, Borneo, this exceptional variety of Hoya finlaysonii features thick, leathery leaves patterned with dark green veins etched across a silvery-green background — a natural mosaic that feels almost sculptural.

Each leaf is uniquely patterned, with raised venation that gives it a tactile, embossed texture. Under bright light, the silvery tone intensifies, creating a beautiful interplay between light and shadow. When mature, the plant produces clusters of creamy white to pink star-shaped flowers with deep red centres that release a rich, sweet fragrance in the evening.

Elegant, resilient, and unmistakably exotic, Hoya finlaysonii ‘Sarawak’ is a favourite among collectors for its architectural foliage and refined charm. Its trailing vines make it ideal for hanging baskets, tall planters, or trained along a trellis to showcase its geometric leaf structure.

Hoya finlaysonii ‘Sarawak’ – Care Guide

Light

Thrives in bright, indirect light, which enhances its silvery base colour and dramatic veining. A few hours of gentle morning sun are beneficial, but avoid intense midday rays. Insufficient light may cause leaves to lose contrast and appear dull.

Watering

Allow the top 3–4 cm of the soil to dry out before watering again. This Hoya prefers a lightly moist environment but is sensitive to overwatering. During the active growing season (spring to summer), water regularly but ensure the pot drains freely. In winter, water sparingly and let the soil dry more thoroughly between waterings.

Temperature and Humidity

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

• Humidity: Enjoys moderate to high humidity (60–80%), similar to its tropical origins. Mist occasionally, use a humidifier, or place on a pebble tray to maintain ideal moisture levels.

Soil and Potting

Use a loose, airy mix such as equal parts orchid bark, perlite, and coco coir or peat-free compost. Good aeration prevents root rot and supports the plant’s epiphytic nature. Repot every 2–3 years in spring once roots begin to fill the pot.

Feeding

Feed every 4–6 weeks during the growing season with a diluted, balanced liquid fertiliser or a Hoya-specific formula. Use a fertiliser slightly higher in phosphorus if you wish to encourage blooming. Stop feeding during winter dormancy.

Pruning and Maintenance

Trim long vines to maintain shape and encourage branching. Never remove the peduncles (flower spurs) — these are perennial structures from which new blooms will emerge season after season. Wipe leaves occasionally with a soft, damp cloth to highlight their intricate veining and maintain their metallic sheen.

Growth and Maturity

A moderate grower, typically producing trailing vines up to 1.5–2 metres long when mature. The leaves grow thick and rigid, ranging from 8–15 cm in length, with each one forming a unique pattern. Under high light and consistent humidity, Hoya finlaysonii ‘Sarawak’ develops dense foliage and frequent flower clusters.

Common Issues

• Yellowing leaves: Overwatering or poor drainage.

• Shrivelled leaves: Underwatering or low humidity.

• Dull colouring: Insufficient light.

• Pests: May attract mealybugs, scale, or aphids — wipe affected areas and treat promptly with neem oil or insecticidal soap.

Background and Benefits

Native to the Sarawak region of Borneo, Hoya finlaysonii grows as an epiphyte in humid rainforests, clinging to trees and absorbing filtered light through the canopy. The ‘Sarawak’ form is especially prized for its pronounced veining and silvery tone, setting it apart from other finlaysonii varieties.

Its bold foliage and easy-going temperament make it a showpiece plant that combines artistry with resilience. Like other Hoyas, it also helps purify indoor air and thrives with minimal fuss, rewarding patient growers with clusters of fragrant, waxy blooms.
