description_en: Genus of about 400 species of mainly herbaceous perennials, some woody-based and evergreen. Occurring in a wide range of habitats from bogs and marshland to alpine areas, they are widely distributed throughout the N. hemisphere, with almost half the species from the Himalayas; a few are also found in the S. hemisphere. They have linear to broadly ovate to obovate, pale to dark green leaves in basal rosettes, and attractive, often salverform, some-times tubular, bell-shaped or funnel-shaped flowers, with usually spreading petals joined at the bases into tubes. The solitary flowers may be clustered together among the leaves, or borne on slender to stout flower-stalks in umbels, whorls, or racemes. In some primulas, the leaves, flower stems, and calyces may be covered with a white or yellow, waxy meal, or "farina". Primulas can be used for most garden sites, from bog and waterside plantings to borders, rock gardens, and bedding; they can also be grown in an alpine house. A few tender species are grown as cool or temperate greenhouse container plants, or as houseplants. Primula is a complex genus, divided into many different botanical sections. In gardens, however, only the following 3 major groupings are recognised; they apply to many, but not all primulas.

hardiness_en: Fully hardy to frost tender.

cultivation_en:

propagation_en: Surface-sow seed of half-hardy and frost-tender species in early spring. Sow seed of hardy species in containers in an open frame, as soon as ripe or in late winter or early spring. Divide between autumn and early spring. Root basal cuttings or offsets in autumn or early spring. Take root cuttings when dormant in winter.

pests_en: Prone to aphids, red spider mites, leafhoppers, vine weevil, slugs, viruses, primula brown core, and grey mould (Botrytis).
