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
'Harry Hotspur' is an evergreen, perennial, alpine auricula, up to 20cm tall, with rosettes of light green leaves. Clusters of dark red-purple flowers with paler edges and white centres, are produced on short stems in mid- to late spring
Primulas are a sight for sore eyes in spring, arriving in a rainbow of colours to add pizzazz to patios and perk up beds and borders.
These cheerful bedding plants offer great value, flowering their hearts out for weeks returning in subsequent years and self-seeding to give you more plants for your money.
