Geranium 'Johnson's Blue' was the first of the brilliant blue geraniums to catch gardeners' eyes. The Royal Horticultural Society gave it the Award of Garden Merit (AGM). The blue of its flowers is hard to photograph and is always more startling when you actually see the plant. The flower stalks can grow quite tall and will droop under the weight of the blossoms. Most gardeners don't bother to stake them, since it is still an attractive plant, even with its floppy habit.
Cut back the flowers after the first bloom, to get sporadic repeat blooms. Often the whole plant can begin to look scraggly and a good shearing is needed to totally rejuvenate it.
'Johnson's Blue' geranium is drought tolerant. It blooms best in full sun, but appreciates some afternoon shade in hot, dry areas. It's very disease resistant and a magnet for bees and butterflies.
