Hoya sp. Hat Som Paen (WA - Prohibited)
release_alert Low Stock - 2 available
Hoya sp. Hat Som Paen is a rarely seen species prized for its refined umbels and beautiful colour contrast. Each blossom opens a clean white, with a vivid pink-purple centre that glows against the petals and deepens as the flowers mature. Once established, it can bloom repeatedly through the warmer months, producing tidy, rounded clusters that really stand out in a collection.

Growing Conditions
- Light: Bright filtered light is ideal. Too little light will reduce blooming, while harsh direct sun can scorch the foliage.

- Temperature: Warm grower; prefers consistent indoor warmth and protection from cold drafts.
- Humidity: Enjoys moderate to high humidity, which supports both foliage quality and flower production.
- Potting Mix: Best in a chunky, free-draining Hoya mix that keeps roots aerated. Learn more in Understanding Hoya Roots.
- Fertiliser: Regular, light feeding through the growing season encourages stronger growth and more umbels—see Grow Hoyas Faster & Get More Flowers.
