Primula veris

Primula veris, commonly known as the cowslip, is a herbaceous perennial flowering plant in the primrose family. It features a basal rosette of leaves and produces clusters of fragrant, deep yellow flowers in the spring.

The species is native throughout most of temperate Europe and western Asia. It typically grows in open habitats such as meadows, pastures, coastal dunes, and clifftops.

It is valued as an ornamental garden plant, having earned the Royal Horticultural Society's Award of Garden Merit. The leaves are traditionally eaten as a salad green, while the flowers are used to flavor country wines, vinegars, and sugared sweets.

In traditional European folk medicine, the roots and flowers were historically prepared as remedies for various ailments. The dried roots contain saponins and phenolic compounds that were utilized in historical apothecary practices.

The plant was significant in Celtic druidic rituals, where it was likely used in magical potions to enhance the absorption of other herbs. It was historically referred to as St. Peter's herb or the 'key of heaven' and features prominently in English rural folklore.
