I am a large, evergreen or semi-deciduous tropical timber tree, known for my rapid growth, distinctive form, and milky latex sap. I am valued as a shade tree, in traditional medicine, and for my lightweight timber.

Native to the Indian subcontinent, Southeast Asia, and Australasia. Widely planted as an ornamental avenue and shade tree across tropical regions.

Requires moderate watering when young to establish a deep root system. Mature trees are relatively drought-tolerant and thrive on natural rainfall in suitable climates.

Prefers full sun to partial shade. Grows tall and straight when planted in open, sunny locations.

Thrives in warm tropical to subtropical climates (20-35°C). Cannot tolerate frost.

Plant in deep, well-drained soil with ample space for its large root system and ultimate height. Due to its large size, it is suitable only for parks, wide avenues, and large estates, not small gardens.

Generally low-demand. A light application of a balanced, slow-release fertilizer in the growing season can benefit young trees. Mature trees rarely need feeding.

Botanical name: Alstonia scholaris (most common species); Common names: Devil Tree, Blackboard Tree, Scholar's Tree, Saptaparni (Sanskrit), Chhatim (Bengali/Hindi); Family: Apocynaceae.

⚠️ CAUTION: Toxic. The milky latex and other parts of the tree contain alkaloids and are considered toxic if ingested, potentially causing gastrointestinal and cardiac issues.

High. As a large, evergreen tree, it contributes significantly to oxygen production, carbon sequestration, and provides substantial shade, cooling the ambient air.

Excellent large shade and avenue tree; bark is used in traditional medicine (Ayurveda) for fever and digestive issues; lightweight timber is used for pencils, matchboxes, and carving; important in cultural and religious contexts in India.

Can become invasive in some non-native tropical areas due to prolific seeding. The roots can be vigorous and potentially interfere with nearby paving or structures. The falling flowers and seed pods can create litter.

Long-lived perennial tree. Can live for 50-100 years or more, reaching heights of 30-40 meters in ideal conditions.
