(='Birch Double') The Border selections of Cranesbill Geranium are valuable fillers for early summer colour in the border or woodland garden. This selection forms a mound of bold green foliage, bearing fluffy double violet-blue flowers tinged with pink. Plants need to be cut back hard after blooming to encourage fresh new foliage. Unlike a lot of other types, this is a sterile form that will not self seed all over the place. Easily divided in spring or early fall. Foliage usually develops good red fall colour.
