The best-known blue Geranium. 'Johnson's Blue' has been the favorite of many gardeners for a long time and it's not hard to tell why. The clear, vivid periwinkle blue flowers are perfectly formed and relatively large at 2" wide.
Immediately after flowering, it's a good idea to shear back the foliage to allow a flush of new growth. This will help to keep the plant more compact and mounded.
The finely cut leaves quickly form wide clumps and are the perfect backdrop for the flowers in late spring. In the fall, the foliage takes on brilliant orange and red tones, extending this perennial's seasonal interest even further.
Homeowner Growing & Maintenance Tips:
Cranesbill is generally quite adapatable to a variety of growing conditions. Though it prefers moist, well-drained soil, it will also tolerate periods of drought once established. For this reason, it is a good choice for southern gardens. Cranesbill will grow in full sun or part shade. In too much shade, however, its habit will be less compact and fewer flowers will be produced. Geraniums are generally considered pest free. They require little care once established, but may be divided every 3-4 years. If the foliage begins to look raggedy by late summer, simply trim it back. A new flush of foliage will quickly take its place.
