Bambusa arundinacea, commonly known as Thorny Bamboo or Indian Thorn Bamboo, is a large, tropical, clumping bamboo species native to the Indian subcontinent. Known for its tall, robust culms, sharp spines, and fast growth, it is widely used for agriculture, construction, erosion control, and bamboo plantations. This species is also valued for its young edible shoots and ability to thrive in arid, degraded soils.

Its thorny branches make it a natural choice for living fences, security hedges, and windbreaks, while its dense growth and tall stature make it suitable for large-scale landscaping and commercial bamboo farming.
