Hoya krohniana 'Super Silver' – A Shimmering, Low-Maintenance Statement Plant

Hoya krohniana 'Super Silver' is a spectacular cultivar of Hoya krohniana Kloppenb. and Siar, first described in 2009. Native to the Philippines, this compact epiphyte features heart-shaped leaves completely dusted in silver – a result of extreme splash variegation. Whether trailing or climbing, it stands out in any collection and produces clusters of star-shaped, sweetly fragrant flowers with the right care and time.

How to Keep Those Silver Leaves Happy
 
Light: Bright, indirect light is essential to maintain the silver pattern. Some soft morning sun is fine.
Water: Allow the top 70 – 80% of the substrate to dry. Use lukewarm, filtered water for best results.
Humidity: Loves 60 – 80% humidity. Group with other plants or place near a humidifier.
Temperature: Keep between 18 – 25°C. Avoid cold drafts and heating vents.
Soil: Use an airy blend of orchid bark, perlite, and coco coir.

Propagation and Semi-Hydro Tips
 
Cuttings: Take 2 – 3 node cuttings and root them in water, moss, or semi-hydro (LECA).
LECA Setup: Performs well in LECA with stable humidity and gentle airflow.
Common Issues and How to Fix Them
 
Yellow Leaves: Usually from overwatering or stale substrate. Let the mix dry out and refresh soil every 2 – 3 years.
Pest Watch: Mealybugs and spider mites can appear. Use insecticidal soap or neem oil and improve airflow.
Brown Edges: Often due to low humidity or salt buildup. Rinse substrate occasionally and increase moisture.
Flowering Tips for the Patient Grower
 
Do not remove old peduncles – flowers return on the same spot.
Keep in a stable location with consistent light and humidity.
Once mature, blooms appear in warm months and release fragrance in the evening.
Placement and Styling Ideas
Train it gently up a small trellis, let it spill from a shelf, or spotlight its silver leaves in a minimalist pot. Hoya krohniana 'Super Silver' adapts well to bright indoor spaces and looks stunning solo or paired with darker foliage companions.
