Geranium × johnsonii 'Johnson's Blue'
cranesbill
Deep lavender-blue, saucer-shaped flowers appear in early summer among deeply divided, mid-green leaves. The loose clusters of lavender-blue flowers, becoming paler at the centre, look lovely weaving in and out of the front of a mixed border or at the base of flowering shrubs. This geranium rapidly forms a dense carpet of foliage, valuable for suppressing weeds, and if cut back after flowering, will usually produce a second flush of flowers later in the summer.
How to care for Geranium × johnsonii Johnson's Blue:
In midsummer rejuvenate plants that are beginning to look jaded, by removing old flowered stems and leaves. Lift and divide large colonies in spring.
