Hoya lacunosa 'Amarillo'

Hoya lacunosa ‘Amarillo’ – golden-blossomed trailing Hoya with soft tropical fragrance

Hoya lacunosa ‘Amarillo’ is a compact, trailing cultivar of Southeast Asian Hoya lacunosa, loved for its warm golden blooms and sweet evening scent. The name ‘Amarillo’ – Spanish for “yellow” – captures the delicate creamy-yellow hue that sets this plant apart from other lacunosa forms.

Originating from humid lowland forests across Thailand, Malaysia, and Indonesia (100–900 m elevation), this small-leaved epiphyte belongs to Hoya section Acanthostemma, known for petite, recurved flowers and frequent blooming.

Hoya lacunosa ‘Amarillo’ combines manageable growth with tropical charm – ideal for collectors who want something refined yet low-maintenance.

What makes Hoya lacunosa ‘Amarillo’ stand out

• Golden tones: Each umbel carries 15–25 small, creamy-yellow flowers about 1 cm across, with a warm honey scent in the evening.
• Compact habit: Produces fine, trailing vines with glossy, leathery leaves around 2–3 cm long.
• Rare cultivar: Still limited in availability and prized for colour shift and reliable bloom cycle.
• Shipping size: Supplied as a rooted plug (approx. ⌀ 2 cm, about 10 cm tall).

Light and watering for Hoya lacunosa ‘Amarillo’

• Light: Bright, indirect light is ideal; too much sun fades leaves, too little slows flowering.
• Watering: Let the top 2 cm of substrate dry before watering again. Avoid dense or soggy mixes.
• Routine: Keep watering consistent – stability encourages more umbels over time.

Warmth, humidity and the ideal substrate mix

• Humidity: 60–80 % supports lush growth and frequent umbels.
• Temperature: Prefers 18–27 °C, minimum 15 °C. Avoid sudden temperature drops.
• Substrate: Loose, airy blend of bark, perlite, and coco coir, or a mineral semi-hydro substrate.
• Airflow: Gentle air movement helps prevent fungal issues and keeps leaves healthy.

Feeding and repotting Hoya lacunosa ‘Amarillo’

• Fertilising: Light feed every 4–6 weeks with a diluted, balanced fertiliser during active growth.
• Repotting: Only when roots fill the pot – usually every 2–3 years.
• Tip: Slightly root-bound plants bloom more readily, so resist overpotting.

Propagation and display ideas

• Cuttings: Roots easily from one- or two-node segments in sphagnum, perlite, or water.
• Display: Trails beautifully from shelves or hanging planters, or climbs a small trellis.
• Pairing: Looks striking beside white-flowering Hoya lacunosa cultivars for contrast.
