Hoya crassipetiolata ‘Splash’ is a captivating houseplant admired for its thick, leathery leaves adorned with distinctive silvery speckles. This unique “splash” variegation gives the foliage a shimmering appearance, making it a highly sought-after plant among enthusiasts. Native to the tropical forests of Southeast Asia, specifically Vietnam and the Philippines, this Hoya grows as an epiphyte, typically clinging to trees or rocks. Its vining habit makes it suitable for hanging baskets or climbing supports, adding a touch of natural beauty to indoor spaces.
Hoya Crassipetiolata ‘Splash’ Care
Light
Hoya crassipetiolata ‘Splash’ thrives in bright, indirect light conditions. Placing it near an east or north-facing window is often ideal, or a sheer curtain can filter direct sunlight from a sunnier window. Direct midday sun can scorch its leaves, leading to damage. Insufficient light, however, can hinder both its growth and the vibrancy of its characteristic splash variegation.
Watering
Water when the majority of the soil mix has dried out. Overwatering can lead to root rot, so ensure proper drainage. Watering frequency varies with pot size, soil, and environment, but is typically every 10 to 14 days. Reduce watering during cooler months as growth slows.
Soil
This Hoya requires a well-draining, airy, chunky substrate to prevent waterlogging. An optimal blend includes orchid bark, perlite, coco coir, and a small amount of potting soil or worm castings. Some growers also include horticultural charcoal for enhanced drainage and to inhibit fungal development.
Temperature and Humidity
Hoya crassipetiolata ‘Splash’ prefers a warm, stable indoor temperature range of 65-80°F (18-27°C). It does not tolerate temperatures below 50°F (10°C) and needs protection from cold drafts. While adaptable to average household humidity, it thrives in moderate to higher levels, around 40-60%. To increase humidity, use a pebble tray or a room humidifier.
Fertilization
During its active growing season in spring and summer, fertilize Hoya crassipetiolata ‘Splash’ with a balanced liquid fertilizer, diluted to half strength, every 4-6 weeks. Fertilization is not necessary during the dormant period in fall and winter.
Enhancing ‘Splash’ Variegation
The distinctive silvery ‘splash’ variegation of Hoya crassipetiolata ‘Splash’ is significantly influenced by light intensity. To maximize the prominent silver flecks on its leaves, provide the plant with bright, indirect light, often slightly brighter than what is needed for basic survival. Positioning the plant where it can receive a few hours of gentle morning sun or filtered light can intensify the ‘splash’ patterns. If natural light is limited, supplementing with a grow light can help maintain vibrant variegation.
Propagating Hoya Crassipetiolata ‘Splash’
Propagate Hoya crassipetiolata ‘Splash’ using stem cuttings. Select a healthy stem with at least two nodes, as roots will develop from these points. Remove leaves from the lowest node.
For water propagation, place the cutting in water, ensuring the node is submerged, and change water weekly. For soil propagation, plant the cutting in a loose, airy mix, burying at least one or two nodes. Keep the rooting medium consistently moist but not waterlogged, and provide warmth and humidity to encourage root development. Rooting can take several weeks to a few months, so patience is beneficial during this process.
Common Problems and Solutions
Yellowing leaves often indicate overwatering, which can lead to root rot. Allow the soil to dry out more thoroughly between waterings, and ensure the pot has adequate drainage. Conversely, shriveling or drooping leaves may signal underwatering, requiring more consistent moisture.
Pest infestations, such as mealybugs and spider mites, can occasionally affect this Hoya. Regularly inspect the plant and wipe down leaves to help prevent these pests. If an infestation occurs, apply insecticidal soap or neem oil.
