Appearance
Avicennia Marina has a striking appearance with its tall height, grayish-brown bark, and thick, leathery leaves. Its leaves are a glossy green on the upper surface, and its lower surface excretes salt, which helps it survive in saline environments. The tree produces small, light green flowers that develop into a woody fruit. Avicennia Marina has a unique root system that grows above the soil, called pneumatophores, which helps it absorb oxygen.
Care Guide
Avicennia Marina is a hardy tree that can tolerate a range of soil types, including sandy, saline, and clay soils. It grows well in full sun to partial shade and requires moderate watering. It can tolerate drought and salt spray but prefers to have moist soil. Fertilizer is not necessary, but a slow-release fertilizer can help promote growth. Avicennia Marina is hardy in USDA zones 10-12.
Common Pests & Diseases
Avicennia Marina is relatively pest and disease-free. However, it can be susceptible to scale insects, which can cause leaf yellowing and drop. These can be controlled with insecticidal soap or neem oil.
Habitat
Avicennia Marina is commonly found on intertidal mudflats and estuaries along tropical and subtropical coasts. It can tolerate high salinity and waterlogging, making it an important species in coastal ecosystems.
