Unknown White Flower

Today I shared flower pictures. I like flowers very much. That's why I photograph different types of flowers. If I see a beautiful flower when I go somewhere, I take a picture of it. The flower I am photographing today was found on the side of the road near my house. Then the picture was taken by my sister. But I don't know the name of the flower. And I saw the flower for the first time today so I don't know much about it.
