Category: Greening Sanjeevi Hills
The picture above, taken at Sanjeevi Hills in Rajapalayam, shows Cassia roxburghii DC., commonly known as the Red Cassia or Red Indian Laburnum, in full bloom. Belonging to the Legume family, this striking flowering tree is admired for its cascading clusters of pink, rose to orange-red blossoms that brighten the landscape during the monsoon months. In Tamil, it is commonly known as Sivappu Kondrai (சிவப்புக் கொன்றை), and in some regions, it is also referred to as vaagai (வாகை).
Cassia roxburghii is a medium-sized deciduous tree that typically grows to a height of 10-15 metres. It develops a broad, spreading canopy with gracefully drooping branches, making it an attractive shade tree. Its compound leaves bear 8-20 pairs of leaflets, adding to its elegant appearance.
In South India, the tree usually flowers between June and August, although the exact flowering period may vary depending on local climatic conditions. Following the flowering season, it produces long, cylindrical seed pods containing several seeds.
Native to South India and Sri Lanka, the species is widely planted across tropical regions as an ornamental and avenue tree. Its spectacular floral display makes it a favourite for parks, gardens, institutional campuses, and roadside landscaping.
Beyond its ornamental value, the tree provides ample shade and contributes to urban biodiversity by attracting pollinators such as bees and butterflies. Its presence at Sanjeevi Hills is a reminder of the rich floral diversity that enhances the natural beauty of Rajapalayam.
