The Welsh believe that the yellow daffodils of early spring flowers bloom specially for the feast of their beloved Saint David, so they are also considered a symbol of Wales this flower. Recently, the Narcissus even pushed less romantic leeks, originally considered the emblem of the country. 
To conquer Wales had many, starting with Caesar. But to suppress failed to anyone. To this day the border between the "land of Cymru" and "good old England" is "the Ditch of Offa", a giant earthen wall erected in the 8th century the Anglo-Saxons, though trying thus to protect themselves from the raids of the inhabitants of the mountains of Heather and heaths. And Wales (it is known not all) is a sovereign Principality, part of the UK, but not formally subordinate it to the monarch. Once shaggy Celtic chiefs said a triumphant conqueror: "Either the war to end, or at least give us Lord, born on our land, and never speaking English." And wise king Edward made him a month of their first child, born on Welsh land: "Here is your master." Since the iron ring Llewelyn, a symbol of power over Wales, belongs to the crown princes. But on the eve of the coronation of a new monarch sacred relic passes to the next heir. 
English symbols and emblems of Wales do not honor, preferring their ancient: leeks (according to legend, Saint David, baptized of the Celts, ordered his followers to attach it to clothing, in order to differ from the pagans) and Narcissus, the favorite flower of Prince Llewelyn. Not really liking there and the English language. Already almost half of the planet to the question "Do you speek English?" answers "Yes!", and in some Northern villages to the West of the "Ditch of Offa" in English almost did not say; stubborn peasants remain quite satisfied with their very ancient and very complicated language that survived almost intact. In England daffodils are considered a symbol of Wales. It's hard to imagine that balanced and phlegmatic Englishmen could as much to get excited about flowers, as it happened to the Dutch during the famous " Tulip fever." Nevertheless England had its "floral fever", though not "Tulip" , and "nartsissov". In the XIX century the whole country was fascinated by the new varieties of daffodils were sold at exorbitant prices. Trading bulbs of daffodils, clever people have managed to create a very significant condition.
