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.

Geranium × johnsonii 'Johnson's Blue' rapidly forms a dense carpet of foliage, valuable for supressing weeds, and if cut back after flowering, will usually produce a second flush of flowers later in the summer.


  • Garden care:
    Incorporate plenty of organic matter when planting and water well in dry weather, especially newly established plants. Apply a generous 5-7cm (2-3in) mulch of well-rotted manure or garden compost around the plant to help seal in moisture, feed the soil, and reduce the need for weeding.

    Deadhead spent flowers regularly to encourage continuous blooming. If the plant becomes too leggy or untidy later in the season, trim lightly to encourage fresh growth and more flowers. Lift and divide large clumps in spring.
