A perennial member of the primrose family, the cowslip, or Primula veris, is commonly found in hay meadows, woodlands and hedgerows, although large swathes of them are now rare. Its tube-like yellow flowers can be seen from April to May and grow in clusters on one side of a long stalk, giving a nodding appearance. This is thought to resemble a set of keys, resulting in common names including St. Peter’s Keys or Keys of Heaven, with folklore saying that the cowslip appeared where St. Peter dropped the keys of heaven.
The name is a corruption of the old English cu-sloppe, or cow pat, reflecting its meadow habitat, while the Latin name veris means Spring. It is the county flower of Northamptonshire, Surrey, Essex and Worcestershire. In tradition, cowslips are associated with May Day, Beltane and weddings, with church pathways and maypoles often decorated with them. One old belief is that if a suitor gives his love cowslips on May Day, they will marry that year. Shakespeare mentions them in both A Midsummers Night Dream and The Tempest.
They are a food plant for the Duke of Burgundy butterfly. The flowers are a traditional flavouring for English wine, while in Spain the leaves are used in cookery. In traditional medicine the flowers are used in sedative teas.
