Primula is one of the great garden genera, embracing the wild primrose and cowslip, the candelabra species that tier their whorls up a stem in damp ground, drumstick kinds topped with tight spheres, auriculas with their chalky farina and painted faces, and jewel-like alpines for the rock garden. Most form flat rosettes of crinkled or mealy leaves and flower from late winter through spring into early summer, in virtually every colour.
