In all moist meadows and swampy places the rambler may come across a multitude of waving flowers which look white in the mass but at close quarters are seen to be pale pink or lilac. They are the Lady’s Smock, one of our best examples of the Cruciferous plants. The country name in many places is Milk-maids or Cuckoo-flower. Abundant throughout Britain.
The flowering period is from March to June.The Observer’s Book of Wild Flowers, compiled by W. J. Stokoe (1957)
