Such as the ones in Flushing Meadows Park:
Or the flowers in Central Park:
Still others are really quite unexpected.
This Moon Flower was growing up the side of a garbage can at the 72nd Street entrance to Central Park. I was a bit startled to see it staring at me boldly as I approached to trash can with my trash, looking at me as if to say , "Don't make me have to show you why you're happy you threw that trash in the can instead of on the ground. What?!?!"
I just wanted to say Thanks NYC! for doing the gardening for me.
