I took this Plant / flower picture during Nature camp to the Nilgiri
Biosphere Reserve –in Avalanche- Kunda Forest Reserve–Mukurthi National Park.
This plant, less than 3 meter, I was told more than 300 years old, which is surprise to me. Though it was not flowering season I was searching for it. Finally I got one cluster of flowers on the way to Folding rocks.
