Primula is a genus of mainly herbaceous flowering plants in the family Primulaceae. They include the familiar wildflower of banks and verges, the primrose. Other common species are P. auricula (auricula), P. veris (cowslip) and P. elatior (oxlip). These species and many others are valued for their ornamental flowers. They have been extensively cultivated and hybridised - in the case of the primrose, for many hundreds of years. Primula are native to the temperate northern hemisphere, south into tropical mountains in Ethiopia, Indonesia and New Guinea, and in temperate southern South America. Almost half of the known species are from the Himalayas.
