This is a specialty of the Derbyshire white peak although it isn't always easy to find. I knew of a large colony down a gorge and fought my way to photograph the flower but on the way back also found some growing by the main path. In the summer sunshine the flowers were visited by a humming bird hawk moth with its long tongue dipping quickly from flower to flower tasting every one in seconds.

It is found in central and northern England more than the southern parts and dotted around in Wales in Scotland. There is little in Ireland.
