Hardy Geranium Johnson’s Blue A old, much loved, hybrid cranesbill, Geranium x johnsonii Johnson’s Blue is a herbaceous, clump-forming perennial with deeply divided mid-green leaves, faintly washed with silver, a lovely foil for the flowers. Single, lavender-blue flowers with darker veins, 2”/5cm wide, are borne throughout summer; they are very attractive to bees. Hardy geranium Johnson’s Blue spreads by means of rhizomes, and makes dense ground cover; it looks particularly lovely as an underplanting for roses.
