Morphological Features

Tricolor Hoya, scientifically known as Hoya carnosa ‘Tricolor’, is a succulent plant belonging to the Apocynaceae family. It is renowned for its thick, waxy leaves and beautiful star-shaped flowers.

Growth Habits

Tricolor Hoya prefers warm and humid environments and can adapt to various indoor light conditions. It thrives best in semi-shaded environments, avoiding intense direct sunlight. The plant’s ideal growth temperature ranges from 15 to 28 degrees Celsius, and it requires a cool and slightly dry environment for dormancy during winter, with temperatures kept above 10 degrees Celsius. If temperatures drop below 5 degrees Celsius, it is susceptible to cold damage, causing leaf drop or even plant death.

Application Scenarios

Tricolor Hoya is ideal as an indoor plant due to its beauty and ease of care. It is suitable for hanging or placing on shelves, allowing it to grow naturally downward, creating an elegant green curtain effect. Additionally, it can be used as a desktop plant or for indoor gardens. The flowers of Tricolor Hoya emit a sweet fragrance, adding a natural ambiance to indoor spaces.

Care Instructions

1. Light: Requires bright, indirect light and should avoid direct sunlight, which can scorch the leaves.
2. Watering: Moderate watering is needed during the growing season, but overwatering should be avoided as the plant is very drought-resistant. In winter, water only when the soil is completely dry.
3. Soil: Well-draining soil is necessary, typically using a soil mix specifically formulated for succulents.
4. Fertilizing: During the growing season, a small amount of low-nitrogen fertilizer can be applied, but not in excess.
5. Propagation: Propagation can be done through stem cuttings, ensuring that the cut parts dry out and form a callus before being planted in the soil to promote root growth.

Seasonal Care

• Spring and Autumn: These two seasons are the growing seasons for Tricolor Hoya, requiring moderate watering and monthly application of a thin fertilizer. Pruning and shaping can be done to promote lush growth.
• Summer: In the hot summer, care should be taken to avoid the intense direct sunlight at noon, and some shading may be necessary. At the same time, increase ventilation to prevent high temperatures and humid environments, which helps prevent diseases and pests.

• Winter: Tricolor Hoya is not cold-resistant, so it should be moved indoors to a place with plenty of sunlight in winter. Reduce the frequency of watering and keep the soil dry to avoid root rot. If the temperature does not drop below 10 degrees Celsius, it can safely overwinter.
