Geranium 'Johnson's Blue'

Plant details

This cranesbill is smothered from mid-summer to autumn with lots of large, dark-veined, lavender-blue flowers that fade to pearl grey as they mature. It is an informal-looking, slightly sprawling plant that looks best allowed to make a dense patch of attractive ground cover with its masses of elegant divided leaves. A superb plant for a cottage garden or informal border where it is close to its neighbours, and is particularly good teamed with old fashioned roses. The Royal Horticultural Society have given it their prestigious Award of Garden Merit (AGM).

But every gardener has Her/His preferances, some of Us have many, and even more of Us like most flowering plants, and that's what ties us in together as Gardeners.

Yes I am a big fan of cranesbills. Johnsons Blue is one of my favourites - such a bright blue, lights up a shady spot. It spreads well and very hardy - a good all rounder, a must for the garden!


Grows well in my clay soil. Planted underneath choysia Sundance which compliments it well.
