Description:
Foliage: The tree features long, lance-shaped, glossy green leaves arranged alternately along the branches. The leaves are dense and provide a lush canopy.
Growth Habit: Polyalthia longifolia typically grows tall with a slender trunk and a pyramidal or columnar shape. The branches are drooping, forming an umbrella-like canopy.

Care Guide:
Light: Plant the Polyalthia longifolia in a location that receives full sun to partial shade. It prefers bright sunlight but can tolerate some shade.
Temperature: It thrives in warm to tropical climates and is sensitive to frost. Protect it from freezing temperatures.
Soil: Use well-draining, fertile soil. The tree is adaptable to various soil types but prefers slightly acidic to neutral pH levels.
Watering: Keep the soil consistently moist, especially during the growing season. Water deeply but avoid waterlogging, as overly wet soil can cause root rot.
Fertilization: Apply a balanced fertilizer during the growing season to encourage healthy growth. Follow the manufacturer's instructions for application rates.
Pruning: Prune to remove dead or diseased branches and to maintain a desirable shape. Regular pruning can also help prevent overcrowding within the canopy.
Mulching: Apply a layer of organic mulch around the base of the tree to retain soil moisture, suppress weeds, and regulate soil temperature.
Pest and Disease Management: Monitor for pests such as aphids or scales. Treat any infestations promptly. The tree is generally resistant to diseases but may be susceptible to certain issues in stressful conditions.
