Feat of survival

The other day I had to pick up someone from the airport, and as usual and expected there was a delay in the arrival. So I was well prepared as I had taken my writing pad and did my work while waiting, outside the airport, under the national highway flyover.  

While jotting my plans and thoughts, I saw this particular plant growing on the wall of the flyover. All healthy and flowering too.  Easily high up on the wall, atleast 15 ft up and with no source of water, other than rain!! 

I guess this is what survival is all about.  While we take such great and delicate care of some plants that we try to cultivate in our garden, but never manage to keep them alive or fresh for long, here's a plant, out in the wild, on its own and against all odds, not just surviving but thriving!
