A rare flower has been rediscovered for the first time in seven years thriving in a nature reserve - thanks to perfect weather conditions and the control of dense vegetation.

The Tubular Water Dropwort, a member of the carrot family of plants, had been threatened with near extinction.

About 130 of the plants were found by the Herts and Middlesex Wildlife Trust team at Rye Meads Nature Reserve near Hoddesdon, Hertfordshire.
