Botanical details

Family: Primulaceae
Native to GB / Ireland: No
Foliage: Semi evergreen
Habit: Clump forming
Genus: Primula are herbaceous or semi-evergreen perennials, forming a basal rosette of simple leaves, with salver-shaped or bell-shaped flowers which may be solitary or carried in an umbel or in whorls on an erect stem
Name status: Unresolved
Horticultural Group: Primrose group primulas are mainly grown as herbaceous perennials, and produce clusters of flowers on individual stems from the basal rosettes, although a few may also have umbel-like flowers. They are either spring-flowering, if grown without protection, or winter- to spring-flowering, if grown as biennial container plants in greenhouses or indoors.
