Out of nowhere

This caught my eye on my way to work.  I am not really sure if they are flowers or weeds but I think it is cool that they are growing out of the sidewalk. 

This makes me think of a little blurb on the introductory pages of my favorite book "A Tree Grows In Brooklyn".  It states: "There's a tree that grows in Booklyn.  Some people call it the Tree of Heaven.  No matter where its seed falls, it makes a tree which struggles to reach the sky.  It grows in boarded-up lots and out of neglected rubbish heaps.  It grows up out of cellar gratings.  It is the only tree that grows out of cement.  It grows lushly. . . survives without sun, water, and seemingly without earth.  It would be considered beautiful except that there are too many of it."

How great is it that such a little thing can put a smile on my face on my way to work.
