Primula vulgaris, the common primrose, is a species of flowering plant in the family Primulaceae, native to western and southern Europe, northwest Africa, and parts of southwest Asia. The common name is primrose, or occasionally common primrose or English primrose to distinguish it from other Primula species also called primroses. None of these are closely related to the evening primroses (genus Oenothera). Etymology The scientific name Primula is a diminutive of the Latin primus, "prime", alluding to the fact that this flower is among the first to appear in spring. The vernacular name has the same meaning: primrose derives from a late Latin form prima rosa, consisting of prima, "first" (feminine), and rosa, "rose". The Latin specific epithet vulgaris means "common", in the sense of "widespread". Description Primula vulgaris is a perennial growing tall, with a basal rosette of leaves which are more-or-less evergreen in favoured habitats. It flowers in early spring in the northern hemisphere (February–April) on slopes and meadows. The leaves are 5–25 cm long and 2–6 cm broad, often heavily wrinkled, with an irregularly crenate to dentate margin. The leaf blade is gradually attenuated towards the base and unevenly toothed. The single stem, extremely short, is hidden in the centre of the leaf rosette. The delicately scented flowers are 2–4 cm in diameter, borne singly on short slender stems. The flowers are typically pale yellow, though white or pink forms are often seen in nature. The flowers are actinomorphic with a superior ovary which later forms a capsule opening by valves to release the small black seeds. The flowers are hermaphrodite but heterostylous; individual plants bear either pin flowers (longuistylous flower: with the capita of the style prominent) or thrum flowers (brevistylous flower: with the stamens prominent). Fertilisation can only take place between pin and thrum flowers. Pin-to-pin and thrum-to-thrum pollination is ineffective. Distribution The native range of P. vulgaris encompasses western and southern Europe. In the north, the distribution area extends from central Norway near the Faroe Islands via the British Isles, Denmark, northern Germany, the Netherlands, Belgium and France to southern Portugal in the south and the tip of North Africa in Algeria. To the east, the range extends through the southern European peninsulas to the Crimea, Balkans, Syria, Turkey and Armenia. Habitat In appropriate conditions, P. vulgaris can cover the ground in open woods and shaded hedgerows. It is found mainly by streams, under
