1.Ailanthus — Introduction & Highlights

Ailanthus — Main Image

Ailanthus excelsa, commonly known as Ailanthus Med or the Tree of Heaven, is a majestic deciduous tree belonging to the Simaroubaceae family. This species is indigenous to the Indian subcontinent and Sri Lanka, where it thrives in diverse environments including disturbed lands, riverbanks, and open forest ecosystems. The tree typically attains impressive heights of 18 to 25 meters, characterized by a straight, robust trunk and a broad, spreading crown that offers substantial shade.

Its leaves are distinctly pinnately compound, extending 25 to 60 cm in length, composed of 10 to 25 ovate to elliptic leaflets that present a vibrant, glossy green hue. The flowers are small, subtly fragrant, and generally light yellow to greenish, emerging in dense panicles during the late spring or early summer months. The bark of Ailanthus excelsa undergoes a transformation from smooth and grayish in its youthful stage to a rougher, deeply fissured texture with increasing age.

While celebrated for its rapid growth and adaptability to varied soil conditions, facilitating its use in soil stabilization and reforestation efforts, it has been noted for its aggressive growth, leading to its classification as an invasive species in some regions outside its native distribution. Within its native range, its resilience and ornamental value are highly regarded, making it a significant component of local flora and traditional practices.
