Flax was the basis of the successful linen industry in the north of Ireland. People from all backgrounds worked in the linen industry, making the flax flower a neutral symbol for Protestant and Catholic traditions. The blue Flax flower is now the emblem of Northern Ireland and is displayed by the Northern Ireland Assembly. In a coronet, it has also appeared on the reverse of the British one-pound coin to represent Northern Ireland. Flax also represents Northern Ireland on the badge of the Supreme Court of the United Kingdom and on various logos associated with it.
