Bombax scopulorum - the white silk cotton tree

There is a HUGE silk cotton tree in the lalbagh gardens. I wonder how old it is ... the trunk is wide and the area around is covered with patches of its silky cotton.  It was a hypnotising sight.. I sat below for a while, taking in the shade and observing the antics of the insects around the cinderalla weed.

The white silk cotton trees i've seen earlier, younger ones, had a greenish tint to their barks. This one was all brown and prickly.
