Campanula medium is a beautiful nostalgic biennial species which flowers profusely from spring to autumn. The showy bell-shaped blue, pink, purple or white flowers will add grace and elegance to your garden. Blooms are single or double flowers and this species has an upright growth habit. Leaves are lance-shaped and arranged in a basal rosette, these measure around 15cm in length. Can be easily grown from seed, but often flowers in the second year. They have long, fairly weak stems so these are better planted in a protected spot out of wind and in a group so they can support each other.
