The white water lily (Nymphaea alba) is the UK's largest wild flower. It is a very popular plant and is more usually found in garden ponds than the cultivated varieties that have coloured petals. A number of ponds in the Forest of Dean and surrounding areas have the wild lilies in them.
However, when we were walking in the nearby Dymock Forest we came upon a pond that had a water lilies with pink petals as well as the commoner white variety. They must have been an introduction by someone seeking to beautify the stretch of water.
