Primula is a genus of 400–500 species of low-growing herbs in the family Primulaceae. They include primrose, auricula, cowslip and oxlip. Many species are grown for their ornamental flowers. They are native to the temperate Northern Hemisphere, south into tropical mountains in Ethiopia, Indonesia and New Guinea, and in temperate southern South America.
Primroses are used as food plants by the larvae (caterpillars) of some Lepidoptera species, including Duke of Burgundy butterfly, Large Yellow Underwing, Lesser Broad-bordered Yellow Underwing, Setaceous Hebrew Character and Silver-ground Carpet.
Some species of Primula are commonly known as polyanthus.Selected species
