This particular Hoya is celebrated for its unusual foliage and cascading growth habit, making it an excellent choice for hanging baskets. Here's a detailed description and care guide for Hoya Rotundiflora:

Description

Hoya Rotundiflora features tiny, round leaves that are thick and succulent-like, growing along its trailing stems. The leaves are dark green and can have a slight glossy appearance. This plant's growth habit makes it particularly suitable for hanging baskets or high shelves where its vines can drape beautifully. It produces clusters of small, star-shaped flowers that are typically light pink or white with a red center, known for their attractive look and sometimes fragrant nature.

Care Guide

Light

Hoya Rotundiflora thrives in bright, indirect light. It can tolerate some direct sunlight, especially in the morning, but should be protected from strong afternoon sun to prevent leaf burn. A position near a window that provides filtered sunlight is ideal, such as behind a sheer curtain.

Watering

Water when the top inch of the soil has dried out. Hoya Rotundiflora prefers to dry out slightly between waterings. Ensure that the pot has good drainage to prevent root rot. During the winter, reduce watering frequency, allowing the soil to dry out more thoroughly.

Humidity

This Hoya prefers high humidity, ideally around 60-70%. Increase humidity around the plant using a humidifier, misting regularly, or placing it on a pebble tray filled with water. High humidity helps mimic its natural tropical habitat.

Temperature

Maintain temperatures between 18°C and 27°C. Avoid exposure to temperatures below 15°C, as cold drafts can harm the plant.

Soil

Use a well-draining, airy potting mix. A mix suitable for cacti and succulents, which typically includes ingredients like perlite, pumice, and orchid bark, works well for ensuring adequate drainage and air circulation.

Fertilisation

Fertilize every four to six weeks during the growing season with a balanced, water-soluble fertilizer diluted to half the recommended strength. During the dormant winter months, reduce fertilization frequency or stop feeding altogether.

Pruning and Maintenance

Prune as needed to control the vines' length and encourage fuller growth. Be careful not to remove the flower spurs (peduncles), as they can produce flowers repeatedly over the years. Regularly cleaning the leaves with a damp cloth can help improve the plant's overall health and appearance.

Pest Control

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

Propagation

Hoya Rotundiflora can be propagated effectively through stem cuttings. Take cuttings that include several nodes, let them 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 Rotundiflora should flourish, offering both visual appeal and an exotic touch to your plant collection with its unique foliage and attractive blooms.
