CANON EOS 450DFritillaria meleagris is a species of flowering plant in the family Liliaceae. Its common names include snake’s head fritillary, snake’s head (the original English name), chess flower, frog-cup, guinea-hen flower, leper lily (because its shape resembled the bell once carried by lepers), Lazarus bell, checkered lily or, in northern Europe, simply fritillary.
The flower has a chequered pattern in shades of green and purple, or is sometimes pure white. It flowers from March to May and grows between 15–40 cm (6–16 in) in height. The plant has a button-shaped bulb, about 2 cm in diameter, containing poisonous alkaloids. It grows in grasslands in damp soils and river meadows at altitudes up to 800 m (2,625 ft).
F. meleagris is native to Europe but in many places it is an endangered species that is rarely found in the wild but is commonly grown in gardens. In Croatia, the flower is known as kockavica and is associated by some with the country’s national symbol. It is the official flower of the Swedish province of Uppland, where it grows in large quantities every spring at the meadows in Kungsängen (Kings meadow), just outside Uppsala, which gives the flower its Swedish name, kungsängslilja (Lily of Kings meadow). It is also found in Sandemar strandängar (Sandemar beach meadows), a nature reserve west of the village of Dalarö in the Stockholm Archipelago.
In the United Kingdom there is some disagreement amongst botanists as to whether F. meleagris is a native species or a long-established garden escapee. The plant was first described in the 16th century by herbalist John Gerard who had only known of it as a garden plant and it was not recorded in the wild until 1736, which has led some to argue that it must be an escapee. However, the fact that its habitat is usually confined to ancient hay meadows and it does not easily spread to adjoining land, leads others to the conclusion that it is a native species which became isolated from the European population when Britain was cut off from mainland Europe after the last glacial period.
The plant was once abundant in the UK, particularly in the Thames Valley and parts of Wiltshire, and was collected in vast quantities to be sold as a cut flower in the markets of London, Oxford and Birmingham. During World War II most of the ancient meadows were ploughed up and turned over to the production of food crops, destroying much of the plant’s habitat. Although a popular garden plant it is now rare in the wild, although there are some notable sites where it is still found, such as the meadows at Magdalen College, Oxford and the Oxfordshire village of Ducklington, which holds a “Fritillary Sunday” festival It is also found in the North Meadow National Nature Reserve, Wiltshire and the Mickfield Meadow nature reserve in Suffolk. In 2002 it was chosen as the County flower of Oxfordshire following a poll by the wild flora conservation charity Plantlife.
