Woo or wow...

I don´t know whether it´s pronounced with a woo or a wow... but it´s a hedge woundwort. It´s recently started showing its face in the local hedgerows. For Wildflower week.  More photogenic perhaps is the bell flower in extra. 
Edit: I now know that it's the "woo" sound that starts the name "woundwort", because at one time it was used to dress wounds.
