Wood sorrel

Wood sorrel Oxalis acetosella, is a common woodland plant found across the UK though less commonly in the east . It is a deliciously delicate white colour with pale purple veins, and pale green heart shaped leaves. 
One of my all time springtime favorites and a good indicator of old woodland. 
I have also included a shot of the beautiful  St Mary's church  Petworth with it's surrounding flowering cherry trees.
