Trapped tree!

I stopped and took this photo in this little street in the 7th arrondissement called Cité Vanneau, because of the superb tree that you can see at its end. I often wonder how plants and trees can grow so well, totally trapped in concrete! I looked up the Cité Vaneau on the Internet and I found out that it's the only street in Paris where all porches are similar - which apparently is very rare... Have a great Saturday everyone, I'll be going to the Melac Vendanges, like every year!
