I believe the flower you are looking at Eccles is Vinca Minor which has two nicknames namely "Periwinkle or Creeping Mytle".
It is a vigourous low growing plant that is an ideal plant should you have a piece of ground you wish to cover quickly.
Chose the first website for identification for you @

Whether it be a member of the Violet family of what larva uses it as its food plant would take more investigation.
Hope it has at least helped in identifing the plant for you.
