County flowers of the United Kingdom
In 2002 Plantlife ran a "County Flowers" campaign to assign flowers to each of the counties of the United Kingdom and the Isle of Man. The results of this campaign designated a single plant species to a "county or metropolitan area" in the UK and Isle of Man.. Some English counties already had flowers traditionally associated with them before 2002, and which were different from those assigned to them by Plantlife, including the white rose for Yorkshire, the poppy for Norfolk, and the cowslip for Essex.
