Photo showing a patch of water lilies with lush green lily pads and white flowers, pictured growing in a shallow stretch of an old overgrown canal, with a garden lawn on one side and a small brick wall on the either. Also pictured growing in the canal is Canadian pondweed (Elodea canadensis), blanketweed and duckweed, all of which are thriving and becoming overgrown as a result of the strong sunshine and exposed position of the water,
