Hoya pubicalyx ‘Royal Hawaiian’ is a fast-growing, vining hoya prized for its long, narrow, glossy green leaves often flecked with subtle silver splash. Its trailing habit makes it perfect for hanging baskets, shelves, or climbing supports. When mature and happy, it rewards patience with clusters of deep burgundy to dark pink, star-shaped flowers that are lightly fragrant and incredibly eye-catching.
 
Care Guide
Light: Bright, indirect light. Can tolerate gentle morning sun, but avoid harsh midday sunlight.
Water: Allow soil to dry out slightly between waterings. Hoyas prefer to dry rather than stay wet.
Humidity: Average household humidity is sufficient, but higher humidity encourages flowering.
Temperature: Thrives in 18–30°C. Protect from cold drafts and temperatures below 12°C.
Soil: Well-draining, airy mix (orchid bark, perlite, coco coir or chunky potting mix).
Fertilizer: Feed monthly during active growth with a diluted balanced or bloom-boosting fertilizer.

Let soil dry slightly to prevent root issues
 
Troubleshooting
Wrinkled or soft leaves: Underwatering or dehydrated roots
Yellow leaves: Overwatering or poor drainage
No flowers: Not enough light or too much nitrogen
Leaf drop: Sudden temperature changes or cold exposure
