African hibiscus

Scientific name: Dombeya calantha K.Schum.

Family: Malvaceae (Hibiscus family)

Origin: Native to Madagascar and parts of Africa.

Morphological Characteristics:

This plant features heart-shaped, rough leaves that give it a distinctive texture. Its most striking feature is the pink, hanging flower clusters that emerge between the leaves. Each cluster contains more than twenty individual flowers, creating a beautiful, cascading effect. The flowering season typically occurs during winter and spring, adding vibrant color to gardens during cooler months.

Growth Habits:

African hibiscus thrives in sunny conditions but can also tolerate partial shade. It is relatively drought-tolerant, though it prefers consistently moist soil. To survive the winter, it requires temperatures above 8°C, although it can withstand short periods of cold. If exposed to frost, the leaves may turn bronze, which is a natural response rather than damage.

Soil Requirements:

It adapts well to various soil types, including sandy loam, but performs best in fertile, well-drained soils.

Growth Rate:

This is a fast-growing species, often reaching heights of 2–3 meters when grown as a shrub. In ideal conditions, it can grow up to 6–7 meters tall, making it suitable for use as a small tree. Propagation is primarily done through cuttings.

Cultivation:

Although not widely cultivated in China, African hibiscus is commonly found in gardens and shrub borders in Florida, USA. It is particularly suited for frost-free regions like Lingnan in southern China. In colder northern areas, it must be grown in greenhouses during winter to protect it from freezing temperatures.

Uses:

Known for its stunning, colorful hanging flower clusters, African hibiscus is a popular ornamental plant. It is ideal for planting in groups in parks, gardens, schools, and public spaces. In frost-free regions, it can be grown outdoors year-round, while in colder climates, it requires indoor protection during the winter months.
