Hoya thomsonii ‘Splash’ is a popular houseplant known for its distinctive appearance. This vining epiphyte, native to the Himalayan foothills, offers a unique aesthetic with its fuzzy leaves and characteristic variegation. Its eye-catching “splash” patterns on the foliage make it a favorite among plant enthusiasts. The plant’s compact growth habit makes it suitable for various indoor spaces, including shelves or hanging baskets.
Identifying Hoya Thomsonii Splash
Hoya thomsonii ‘Splash’ is recognized by its unique leaf characteristics. The oval-shaped leaves are often softly cupped and covered in fine, dense hairs, giving them a velvety texture. This fuzzy foliage helps the plant retain moisture and offers protection from intense light in its native high-altitude forest environment. The plant typically exhibits a vining or trailing growth habit.
A distinguishing feature of the ‘Splash’ variety is the silver flecks that appear on its green leaves. This variegation can vary in intensity and pattern. The silver markings create a striking contrast with the green base color, adding to the plant’s ornamental value.
Hoya Thomsonii Splash Care
Light Needs
Hoya thomsonii ‘Splash’ thrives in bright, indirect light. Placing the plant near north or east-facing windows provides suitable filtered sunlight. Brighter indirect light can enhance the silver “splash” variegation on the leaves. Direct, harsh afternoon sun should be avoided as it can scorch the foliage.
Watering
Allow the soil to dry out significantly between waterings to prevent root rot, as Hoyas are semi-succulent and store water in their leaves. Check soil moisture by sticking your finger into the soil; if it feels dry, water thoroughly until it drains from the bottom. Promptly empty any excess water from the drainage tray.
Soil Requirements
A well-draining and airy potting mix is suitable for Hoya thomsonii ‘Splash’, mimicking its epiphytic nature. A recommended blend includes orchid bark, perlite, and coco coir to ensure proper drainage and aeration. A common ratio is 40% orchid bark, 30% perlite, and 30% peat-free compost or coco coir. This chunky mix allows for good air circulation around the roots, preventing waterlogging.
Temperature and Humidity
Hoya thomsonii ‘Splash’ prefers warm, consistent temperatures, ranging between 16-24°C (60-75°F). It can tolerate slightly cooler conditions, with a minimum temperature around 10°C (50°F). High humidity levels are beneficial, with a range of 50-70%. Grouping plants or using a humidifier can help increase ambient humidity, especially in drier indoor environments.
Fertilizing
During the active growing seasons of spring and summer, fertilize Hoya thomsonii ‘Splash’ every 4-6 weeks. Use a balanced liquid fertilizer, diluted to half or quarter strength, to support healthy growth and potential blooming. Fertilizing can be reduced or stopped entirely during the winter months when the plant enters a period of slower growth.
Propagating Hoya Thomsonii Splash
Propagating Hoya thomsonii ‘Splash’ is done through stem cuttings. Select a healthy stem with at least one or two nodes, ensuring it is not overly woody. Make a clean cut with sharp, sterile pruners. Remove any lower leaves that would be submerged in your chosen rooting medium.
Cuttings can be rooted in water, sphagnum moss, or a perlite/soil mix. For water propagation, place the cutting in a jar with water, ensuring the nodes are submerged but leaves are not. Sphagnum moss or a light, well-draining potting mix also work well, providing a moist but not soggy environment. Provide warm and humid conditions to encourage rooting, which occurs within 3-5 weeks.
Troubleshooting Common Hoya Thomsonii Splash Problems
If the plant’s “splash” variegation fades, it indicates insufficient light; adjusting to a brighter, indirect location can restore the patterns. Yellowing leaves often signal improper watering, with overwatering causing soft, mushy leaves and underwatering causing dry, wrinkled foliage. Adjusting the watering schedule to allow the soil to dry between waterings can resolve this.
Drooping or wrinkled leaves suggest underwatering, indicating the plant’s succulent leaves are depleting stored water. A thorough watering can revive the plant. A lack of new growth or flowering might stem from inadequate light, suboptimal temperatures, or nutrient deficiencies, which can be addressed by adjusting care practices. Pests like mealybugs or spider mites can affect the plant; these can be treated with houseplant pest solutions such as neem oil or insecticidal soap.
