Saptaparni, also known as Alstonia Scholaris, is a sacred, evergreen tree native to the Indian subcontinent and Southeast Asia. Commonly called the Blackboard Tree, Devil Tree, or Scholars Tree, Saptaparni has long held significance in Ayurvedic traditions, urban landscaping, and spiritual beliefs. But what truly sets this tree apart is its rare ability to release oxygen at night, making it one of the most valuable oxygen-producing trees for plantation in India.
In a world struggling with rising pollution levels, especially in urban and semi-urban Indian zones, planting oxygen trees isn’t just a green gesture—it’s an ecological necessity. Let’s dive deep into the numerous benefits, characteristics, and plantation tips for the Saptaparni tree.
What Makes Saptaparni Unique?
Unlike most trees that release oxygen during the day through photosynthesis, Saptaparni releases oxygen at night, thanks to a specialized form of photosynthesis called Crassulacean Acid Metabolism (CAM). While this trait is most commonly associated with succulents and certain desert plants, Alstonia Scholaris exhibits similar properties that enable it to improve night-time air quality.
