About this plant

Geranium 'Johnson's Blue' is a popular and beloved perennial plant known for its vibrant blue flowers and attractive foliage. This hardy geranium, a hybrid between Geranium himalayense and Geranium pratense, is prized for its long blooming period and its ability to thrive in a variety of garden settings. In summer, 'Johnson's Blue' produces a profusion of bright blue flowers with a hint of lavender, each about 2 inches in diameter with five petals. The foliage is deeply divided, with each medium green leaf having multiple lobes that give it a delicate, fern-like appearance, forming a dense, mounding clump.

'Johnson's Blue' thrives in full sun to partial shade and is a versatile and attractive plant for borders, rock gardens, and ground cover. Its vibrant flowers pair well with other perennials such as roses, peonies, and salvias, making it an excellent choice for cottage gardens and informal garden designs.

Design tip

Thread generous drifts through perennial borders so the flowers naturally weave between neighboring plants without overwhelming the composition. Contrast the soft, mounded habit with upright bloom spikes and bold foliage to create movement, balance, and lasting seasonal interest.
