Geranium 'Johnson's Blue'

Johnson's Blue Geranium

Geranium ‘Johnson’s Blue’ — commonly called Johnson’s Blue Cranesbill — is a classic, long-blooming perennial valued for its clear blue flowers and vigorous, spreading habit. It forms a mounded clump of deeply cut, soft green foliage, topped in late spring to early summer with masses of saucer-shaped, sky-blue flowers accented by darker veining and a pale center. Its spreading nature makes it an excellent groundcover in sunny to partially shaded gardens.
