Hoya lacunosa 'Laos'

Hoya lacunosa ‘Laos’ – silver-splashed leaves, cinnamon-scented blooms, naturally compact

Hoya lacunosa ‘Laos’ is a beautifully patterned locality form of Hoya lacunosa originating from the tropical forests of Laos. Its teardrop-shaped leaves shimmer with fine silver mottling, and new growth often flushes soft pink to violet before maturing into a glossy deep green.

Native to Southeast Asia, this species grows as an epiphyte in the humid lowland and foothill forests of Thailand, Malaysia, Indonesia, and Laos (100–900 m elevation). The ‘Laos’ form was collected in northern Laos and selected for distinct silver patterning and subtle coloration.

When mature, it produces delicate, fuzzy, cream-white blooms with a sweet, cinnamon-like fragrance that fills the air at dusk – a signature scent of lacunosa Hoyas.

Supplied as a rooted plug ca. ⌀ 2–3 cm, approximately 10 cm tall – ready to establish quickly in your collection.

What makes Hoya lacunosa ‘Laos’ special

• Silver-splashed foliage: Fine, natural speckling that stays visible even in moderate indoor light.
• Colourful new growth: Fresh leaves often blush pink or violet before turning green.
• Cinnamon-scented blooms: Umbels of 15–25 cream-white flowers, each about 1 cm across.
• Compact growth habit: Trails neatly from pots or climbs small supports without tangling.
• Collector’s origin: Distinct Lao selection known for reliable silver patterning and fragrance.

Natural habitat and growth of Hoya lacunosa ‘Laos’

In native forests, Hoya lacunosa grows on tree trunks and branches under filtered light, with constant air movement and humidity year-round.

Hoya lacunosa ‘Laos’ keeps these preferences in cultivation – thriving in bright, indirect light, airy substrates, and consistent but moderate watering. Unlike many variegated Hoyas, this form maintains its silver pattern even under typical indoor conditions, making it well suited to homes and smaller urban setups.

Care guide for Hoya lacunosa ‘Laos’

Light

Bright, indirect light keeps leaves compact and preserves the silver splash. Avoid harsh midday sun on glass, which can scorch foliage.

Watering

Let the top 2 cm of substrate dry before watering again. Aim for evenly moist, never soggy – roots dislike standing water.

Humidity

Prefers 60–80 % relative humidity, but tolerates typical room humidity if watering is steady and air is not completely stagnant.

Temperature

Ideal range is 18–27 °C. Avoid prolonged drops below 15 °C to keep growth steady.

Substrate

Use an open, breathable mix with bark, perlite, and coco coir, or a mineral semi-hydro base. The key is fast drainage with good oxygen at the roots.

Feeding

Apply a mild, balanced fertiliser every 4–6 weeks during active growth. Light, regular feeding is better than heavy, irregular doses.

Propagation

Easy from one- or two-node cuttings rooted in water, perlite, or sphagnum. Warmth and moderate humidity speed up rooting.

Repotting

Repot every 2–3 years or once roots clearly fill the pot. Slightly root-bound plants tend to flower more reliably.

Growth speed

Moderate to fast once established in warm, bright conditions with a stable watering rhythm.

Toxicity

Generally considered non-toxic to humans and pets. As with all Hoyas, avoid ingestion and contact with latex sap.

Common issues with Hoya lacunosa ‘Laos’ and causes

• Yellowing leaves: Usually from overwatering or compact soil – improve drainage and increase the drying interval between waterings.
• Wrinkled leaves: Often due to underwatering or very dry air – adjust watering rhythm and raise humidity.
• Pale foliage: Typically caused by too much direct sun – move to softer, filtered light.
• No blooms: Needs high, steady light and a stable position – Hoya lacunosa dislikes frequent relocation.
• Pests: Occasionally mealybugs or mites – remove early and treat with neem oil or mild insecticidal soap.
