Hoya Pubicalyx Silver Splash

Hoya Pubicalyx is native to the Philippines, and it was first collected in Luzon Island in 1913. In nature, this Hoya is found in humid regions and thrives under the canopy of trees under indirect bright sunlight.
How to Care for your Hoya Pubicalyx
Light
In its natural habitat, the Hoya Pubicalyx grows under the canopy of trees. This is why bright indirect sunlight is essential for its growth. East-facing windowsills are an excellent choice, as this gives your plant some exposure to morning sun and indirect light for the rest of the day.
Exposure to morning sun (which is less harsh) is fine and encourages your Hoya’s foliage to grow vibrant.
On the other hand, keeping the plant under direct sunlight during afternoon and midday sun can burn it. You can use a 20-40% shade cloth to filter harsh light.
Water
Hoya Pubicalyx is a relatively drought-resistant plant but still requires watering regularly. The ideal time to water is when the top 2 inches of the soil are dry. Overwatering this plant can lead the roots to remain in standing water and increase the chances of fungal infections and root rot. 
Filtered water and rainwater are best suited for plant health as hard water can be detrimental and leave water marks on the leaves. Make sure to remove the excess water from the saucer when you’re done watering. 
Humidity
Being a tropical plant, one thing that your plant loves is humidity! 60-70% humidity is ideal, but it can also be hard to maintain in some climates. 
Regular misting, using a humidifier, or placing your plant on a pebble tray are some ways you can create humidity for your plant. Again, it is better to use filtered or rainwater as it is good for the plant and prevents water spots from forming on the leaves. 
Temperature
The tropical regions where Hoya Pubicalyx is naturally found are hot and humid. Therefore, the ideal temperature range for this plant is about 60-75 degrees F (16 – 24 degrees C).
Furthermore, you must ensure that the temperature doesn’t drop below 50 degrees F (10 degrees C) in winter. Shift your plant to warmer areas when things get chilly. Your plant is not cold-hardy.
Growth
Hoya Pubicalyx is a fast-growing plant, and its vines can grow up to 20 feet (6 meters) long, given that all its nutritional needs are being met. New plants can take 1-2 years before they start blooming, and after that, they bloom in spring and summer. 
The flowers are star-shaped, small in size, and grow in clusters. As we already discussed, there are a variety of cultivars that produce different color variations. The flowers emit a sweet fragrance at night.
