Wild Flower?

My day off saw Mum and I checking out a new (for us both) shopping location in Basingstoke ... I will be going back!

Afterwards,we headed to Old Basing and had a lovely relaxing lunch in an old pub next to the River Lodden.  I then walked along the river towards Basing House and back.  There wasn't too much to inspire me photograpic-wise, but I was intrigued by these flowers along the path and bankside.  A google search has failed to identify them ... perhaps someone can give then a name!
