Hearts can be found in all sorts of unique places.  I have a small collection of hearts that I have found in different places I have travelled to.  I am also always on the hunt for heart shaped rocks when I walk a beach.  When I was out walking at a local park I was noticing how the leaves were shaped like hearts.  Even better, they were emerald in colour!  Perfect for this prompt.

You can interpret heart in any way you want.  Who has your heart?  What is the heart of your home, city, workplace, etc?  Or, go with literal like I did.  A green heart!
