Primula vulgaris (primrose, syn. P. acaulis (L.) Hill) is a species of flowering plant in the family Primulaceae, native to western and southern Europe (from the Faroe Islands and Norway south to Portugal, and east to Germany, Ukraine, the Crimea, and the Balkans), northwest Africa (Algeria), and southwest Asia (Turkey east to Iran). The common name is primrose, or occasionally common primrose or English primrose to distinguish it from other Primula species also called primroses.
It is a perennial growing 10–30 cm (4–12 in) tall, with a basal rosette of leaves which are more-or-less evergreen in favoured habitats.
The leaves are 5–25cm long and 2–6 cm broad, often heavily wrinkled, with an irregularly crenate to dentate margin, and a usually short leaf stem. 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.
