Hoya occultata 'Splash' – Compact Sulawesi Houseplant with Speckled Leaves & Yellow Flowers

Small in size, but big in character: Hoya occultata 'Splash' is a rare tropical shrub from Sulawesi that brings structure and color to even the smallest corners of your home. Its firm, pale green leaves are dusted with stable silvery-white splash patterns — and unlike many variegated plants, this one keeps its speckles regardless of lighting.

Come blooming season, this compact beauty surprises with creamy-white bell-shaped flowers, tipped in warm yellow. The blooms last over a week and smell faintly sweet — a quiet reward for those who give it the right light and care.

Where it comes from – and how it grows indoors

Hoya occultata 'Splash' comes from the tropical rainforests of Sulawesi, where it grows epiphytically on tree branches in humid but well-ventilated conditions. Unlike most hoyas, this one doesn’t climb — it stays low, with a bushy habit and compact profile.

Temperatures in its native habitat range between 18–30 °C with steady year-round humidity. Indoors, this plant is slow-growing but long-lived, and ideal for spots with filtered light and moderate airflow. When mature, it may reward you with flowers without needing high humidity or extreme care.

How to care for Hoya occultata 'Splash'

  
Light: Bright, indirect light is ideal; avoid direct midday sun
  
Water: Allow the top 2–3 cm of substrate to dry before watering again
  
Humidity: Average indoor humidity (40–60 %) is more than enough
  
Temperature: Keep between 18–29 °C; avoid exposure below 12 °C
  
Soil: Use a chunky, airy mix (orchid bark, coco coir, perlite)
  
pH preference: Slightly acidic to neutral (approx. 6.0–6.8)
  
Pot choice: Always use a container with good drainage
  
Fertilizing: Apply a mild liquid fertilizer every 3–4 weeks during active growth
  
Propagation: Stem cuttings root easily in water or semi-hydro substrate
  
Hydroponics: Adapts well to LECA and other inert growing systems
  
Pruning: Lightly prune after blooming to encourage bushy growth

Typical problems and how to handle them

  
Mealybugs or scale: Wipe affected areas with alcohol or treat with neem oil
  
Root rot: Caused by overwatering or dense soil — repot and reduce moisture
  
Yellowing leaves: Usually linked to soggy soil or poor drainage
  
Sun scorch: If leaves go pale or crispy, reduce direct sun exposure
  
Drooping growth: Happens if airflow is too low — place near light ventilation

Other helpful details to know

It doesn’t demand special treatment or high humidity, and once settled, it may flower yearly. The combination of stable splash, compact habit, and ease of care makes this a go-to option for shelf or desktop greenery.
