The most common, P. sinensis, is not hardy in winter frost areas. Primula sinensis has dinstinctive, bonnet-shaped calyces. This section contains leathery-leaved, evergreen alpine plants which, when not in bloom, are often mistaken for succulents. Many are commonly grown in a moist section of the rock garden. Some of the exhibition auricula hybrids have been cherished by gardeners for centuries.
Propagation is by offsets or seed.
As the name implies, the flowers are contained in dense head-like umbels. Plant parts are generally farinose and hairy. White farina dusting the dark purple flowers adds to the charm of these late-flowering plants. Plants need partial shade with adequate summer moisture and good drainage. Propagate by fresh seed or division after flowering.
