I know you've seen these all over.  They are called oxeye daisies.  

 

You may know them as Leucanthemum vulgare.  Oxeye daisy is extremely common, even weed-like, throughout much of North America, in waste places, pastures, meadows, and roadsides.

 

I've read that farmers dislike them because if eaten by cattle, they can produce an unwanted flavor in milk.  

 

Even though they are taking over a large area of my garden, I still love them.  They are cheerful, and make me smile.

 

Psst...we put a few young leaves (lighter green ) in our spring salads, for an interesting break from the norm.  Remember to taste just a tiny bit when trying something new from the wild.  And of course, be positive in your identification.  We use Peterson Field Guides to positively identify Edible Wild Plants.  

 

HAPPY GARDENING!!!!!
