The Hoya Rundumensis 'Splash' is a captivating and visually appealing variety of the Hoya family, celebrated for its striking foliage that features speckled or "splashed" variegation. This plant is valued for both its ornamental leaves and its ability to produce lovely flowers, making it a favorite among Hoya collectors. Here's a detailed description and care guide for Hoya Rundumensis 'Splash':

Description

Hoya Rundumensis 'Splash' features small to medium-sized, oval-shaped leaves that are deep green with a distinctive "splashed" pattern of lighter green or silver. This variegation gives the leaves a shimmering appearance, particularly under bright lighting conditions. Like many Hoyas, this plant is a vining species, making it suitable for hanging baskets or as a climbing plant with support. It produces clusters of small, star-shaped flowers that are typically pink or white, adding to its ornamental appeal.

Care Guide

Light

Hoya Rundumensis 'Splash' thrives in bright, indirect light. The variegation on the leaves can become more pronounced with adequate lighting. However, it is important to protect the plant from direct sunlight, especially during the hottest parts of the day, to prevent leaf burn. A spot near a window with a sheer curtain is ideal.

Watering

Water this Hoya when the top inch of soil feels dry to the touch. It prefers to dry out slightly between waterings. Good drainage is essential to avoid root rot, a common issue in overly wet soils. During the winter, reduce the frequency of watering, allowing the soil to dry out more completely.

Humidity

High humidity levels, around 60-70%, are preferred by Hoya Rundumensis 'Splash'. To increase humidity, use a humidifier, mist the plant regularly, or place it on a pebble tray with water. This mimics its natural tropical environment and promotes healthy growth and flowering.

Temperature

Maintain temperatures between 18°C and 27°C. Avoid placing the Hoya in locations with cold drafts or sudden temperature fluctuations, as it does not tolerate cold well.

Soil

Use a well-draining, airy potting mix. A mix designed for epiphytes, such as orchid mix containing perlite, pine bark, and peat moss, works well. This type of soil provides the necessary aeration and drainage that Hoyas need.

Fertilisation

Fertilize every four to six weeks during the growing season (spring through summer) with a balanced, water-soluble fertilizer diluted to half strength. Reduce fertilization during the winter months when the plant's growth naturally slows.

Pruning and Maintenance

Prune as needed to control growth or remove any unhealthy or dead foliage. Avoid cutting off the flower spurs (peduncles) where the flowers bloom, as they can produce flowers repeatedly. Regularly cleaning the leaves with a damp cloth can also help improve the plant's photosynthesis efficiency.

Pest Control

Regularly inspect for pests such as aphids, mealybugs, and spider mites. Treat any infestations promptly with neem oil or an appropriate insecticidal soap, ensuring thorough coverage of the plant, especially the undersides of leaves.

Propagation

Propagation of Hoya Rundumensis 'Splash' is typically done through stem cuttings. Take cuttings that include several nodes, allow them to dry for a day to form a callus, then plant them in a suitable potting mix. Keep the soil moist and warm to encourage rooting.

By following this detailed care guide, your Hoya Rundumensis 'Splash' should thrive, bringing beauty and a touch of the exotic to your indoor plant collection with its unique variegated foliage and charming flowers.
