The Adansonia gregorii, or Boab Tree, is a unique and iconic deciduous tree native to northern Australia, known for its swollen trunk, distinctive silhouette, and cultural significance. Growing up to 10 to 15 metres, it has a broad, bottle-shaped trunk used for water storage and produces large, creamy-white flowers with a sweet fragrance.
