Hoya callistophylla
Hoya callistophylla
A breathtaking epiphytic plant prized for its unique, stiff leaves that feature a dramatic dark green 'veining' pattern against a lighter lime-green background. Native to the rainforests of Borneo, this Hoya is a slow-growing climber that produces clusters of small, fragrant, star-shaped flowers that are typically creamy-yellow with red centers.

Considered non-toxic to cats and dogs. However, like most Hoyas, it contains a milky sap that can cause mild skin irritation or stomach upset if ingested in large quantities.
Care Guide
Light: Place in bright, indirect sunlight. It can tolerate a small amount of morning sun, but direct afternoon sun will scorch the leaves. ### Watering: Use the 'soak and dry' method. Allow the top 50% of the soil to dry out before watering thoroughly. Avoid letting the plant sit in standing water. ### Humidity: Thrives in high humidity environments (60% or higher). If your home is dry, use a humidifier or a pebble tray. ### Soil: Requires an extremely airy and chunky potting mix. A blend of orchid bark, perlite, coco coir, and horticultural charcoal is ideal. ### Temperature: Keep the plant in temperatures between 65°F and 80°F. Do not let it drop below 60°F as it is sensitive to cold. ### Seasonal Tips: During winter, growth slows; reduce watering frequency and stop fertilizing. ### Common Issues: Overwatering is the most common cause of death. Check for mealybugs in the crevices of the leaves.
