Pete's Walks - Rest-harrow
Photo taken 18/07/06 on Pitstone Hill, Bucks.
A flower I've come across a few times on my walks, I remember seeing a lot of it on the track heading east of Royston on the last day of my Berks-Essex Walk. It is so-called because its tough stems used to tangle up on harrows in the Middle Ages.
