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.
