10 - 15cm Hoya Cinnamomifolia House Plant 10,5 cm Pot

Hoya cinnamomifolia is a striking species native to Java, Indonesia, known for its vibrant green foliage and unique flowers. It belongs to the Apocynaceae family and is a favourite among collectors due to its easy-care nature and eye-catching blooms.

Leaves

The leaves of Hoya cinnamomifolia are thick, leathery, and slightly glossy, with a deep green colour. They are elongated and lanceolate, often featuring prominent veins. The leaves' texture and structure allow the plant to store water efficiently, making it somewhat drought-tolerant.

Flowers

One of the most remarkable features of this plant is its flowers. The blooms appear in clusters, forming beautiful umbel-like arrangements. The petals are deep burgundy or reddish-purple with a contrasting lime-green corona in the centre. These flowers are waxy, slightly fuzzy, and emit a pleasant fragrance, particularly in the evening.

Growth Habit

Hoya cinnamomifolia is a twining vine that can grow quite long when given the right conditions. It produces tendrils that wrap around supports, making it an excellent choice for trellises, hanging baskets, or mounted displays. Growth is moderate, with new leaves and flower buds emerging in warm, humid conditions.

Care Guide

Light Requirements

This Hoya prefers bright, indirect light. Too much direct sunlight can cause leaf scorch, while insufficient light may hinder flowering. If grown indoors, an east- or west-facing window is ideal. A few hours of morning sun can be beneficial, but intense afternoon sun should be avoided.

Temperature & Humidity

Warm temperatures between 18–30°C (65–86°F) are ideal for Hoya cinnamomifolia. It is not cold-tolerant and should be kept above 10°C (50°F) at all times. Humidity levels above 60% are preferred, but the plant can adapt to lower humidity if necessary. If indoor air is dry, occasional misting or using a humidifier can help maintain optimal conditions.

Watering

Water the plant when the top 2-3 cm of soil feels dry. Overwatering can cause root rot, so ensure the soil dries out slightly between waterings. In winter, reduce watering frequency as the plant's growth slows. Always use room-temperature, non-chlorinated water to avoid shocking the roots.

Soil & Potting Mix

A well-draining, aerated potting mix is essential. A suitable mix includes orchid bark, perlite or pumice, coco coir or peat moss, and a small amount of charcoal for improved drainage. This ensures oxygen reaches the roots and prevents water from sitting in the soil.

Fertilisation

During the growing season (spring and summer), feed with a balanced liquid fertiliser every 2-4 weeks. To encourage flowering, a fertiliser with higher phosphorus content can be used. Reduce feeding in autumn and winter when growth slows.

Potting & Repotting

Repotting is only necessary every 2-3 years or when the plant outgrows its pot. Choose a slightly larger container with drainage holes to prevent excess moisture retention. Terracotta or breathable plastic pots work well for maintaining root health.

Pruning & Maintenance

Pruning helps control the plant's shape and encourages bushier growth. Avoid cutting off flower peduncles, as Hoyas rebloom from the same stalks. Cleaning the leaves occasionally with a damp cloth removes dust and improves photosynthesis.

Propagation

Stem cuttings are the easiest way to propagate Hoya cinnamomifolia. Cuttings should include at least one node and can be rooted in water, sphagnum moss, or a well-draining mix. Rooting usually takes between 2-6 weeks, depending on temperature and humidity.

Common Problems & Solutions

Yellowing leaves are often due to overwatering, while wrinkled leaves may indicate underwatering or low humidity. If the plant does not flower, it may not be receiving enough light or nutrients. Root rot can occur if the soil remains too wet, so using a well-draining mix is crucial. Common pests include mealybugs, spider mites, and aphids, which can be managed by wiping the leaves with neem oil or insecticidal soap.
