White Flowers

Today I had to collect something from my daughter’s home and on my way home I spotted these white flowers on the opposite side of her drive. I have never seen them in previous years and assume that they are a ‘weed’, but a very pretty one. I have included as an extra the whole plant in the hope that someone will be able to identify it for me.
 
An afternoon of catching up with chores before the weekend. It has been very cold today and I wore my down jacket to walk to my daughter’s home and into the village shops.
