Hoya sp. Lai Chau 'Splash' – Climbing Hoya with Speckled Foliage

This rare form of Hoya from northern Vietnam stands out with its glossy, medium-green leaves covered in natural silver speckles. Known in cultivation as Hoya sp. Lai Chau 'Splash', it climbs or trails with ease and develops compact internodes and semi-succulent leaves. With time and the right care, mature plants may reward you with clusters of creamy-white star-shaped blooms that release a sweet evening scent. The silvery flecking on the foliage varies slightly between leaves, giving each plant a unique appearance.

Highlights of Hoya sp. Lai Chau 'Splash'

  
Origin: Native to the montane forests of Lai Châu, Vietnam

Native Environment and Growth Habit

Hoya sp. Lai Chau 'Splash' comes from evergreen lower montane forests in northern Vietnam, at elevations of 800–1,000 m. There, it grows epiphytically in filtered light, anchoring to mossy bark and limestone. Temperatures average between 18–30 °C with high year-round humidity. Indoors, it adapts well to bright indirect light and a stable environment. Its twining habit benefits from vertical support, but it can also trail from shelves or hanging pots. As a tropical vine, it grows slowly but steadily under the right care. Like other Hoyas, it produces latex sap and should be kept out of reach of pets or children.

Hoya sp. Lai Chau 'Splash' – How to Keep It Happy

  
Light: Bright indirect light year-round; protect from direct midday sun
  
Watering: Let the top 2–3 cm of soil dry out before rewatering
  
Humidity: Regular room humidity is fine if there's airflow; higher levels support faster growth
  
Temperature: Ideally 18–29 °C; avoid drops below 12 °C
  
Substrate: Airy mix with orchid bark, perlite, coco husk, and a touch of organic matter
  
Fertilizing: Every 3–4 weeks with a diluted balanced liquid feed
  
Repotting: Only when roots outgrow the pot—this Hoya prefers slightly tight quarters
  
Pot choice: Use breathable containers with drainage—terracotta or slotted pots work well
  
Support: Provide a moss pole, small trellis, or let it trail naturally
  
Hydroponics: Suitable for semi-hydro setups if drainage and oxygen are ensured

Encouraging Flowers Indoors

  
Timeframe: Blooms may appear after 2–3 years with stable conditions
  
Photoperiod: Keep light exposure long (~14 hours) to encourage blooming
  
Peduncle care: Don’t remove dried flower stalks—they may rebloom
  
Pot stress: Slightly rootbound plants often flower more readily

Common Problems and How to Handle Them

Pests:
  
Spider mites: Can appear in dry air—rinse foliage and improve ventilation
  
Mealybugs: Remove with alcohol-dipped swabs or neem-based products

Care issues:
  
Leaf drop: Often due to overwatering or sudden temperature shifts
  
Root rot: Caused by poor drainage—use a fast-drying substrate
  
Discolored leaves: Brown edges suggest underwatering or nutrient imbalance
