Geranium 'Johnson's Blue'

Geranium 'Johnson's Blue': The Cottage Garden's Favourite Blue

Some plants need a pep talk. This one just shows up in that lavender-blue, darker veins and all, looking like the coolest shirt at the cottage. CLASSIC. CALM. NEVER OUT OF STYLE.

Plant Characteristics:

• Botanical Name: Geranium × johnsonii 'Johnson's Blue'
• Common Name: Cranesbill, Hardy Geranium
• Height: 30–60 cm (1–2 ft)
• Spread: 60–75 cm (24–30 in)
• Flowers: Lavender-blue with darker veins, about 5 cm (2 in) across
• Bloom Time: Early to midsummer (June to July)
• Foliage: Deeply lobed, medium green leaves in a loose mound
• Features: Rabbit resistant, good for cutting

Where to Plant: Use it at the front or middle of a cottage-style border or let it spill over a low wall, and it makes a useful filler as early bloomers fade. It is very hardy and handles most soils, including heavier clay, as long as it isn't waterlogged.

Companion Plants: Plant Leucanthemum 'Starburst' behind the cranesbill for crisp white daisies from June to August that stand 80 to 120 cm tall. Rudbeckia hirta adds golden yellow from June to September, a classic partner for blue. Tuck Sanguisorba 'Little Angel' in front for small burgundy flowers from early summer to early fall at 20 to 30 cm. Give this trio full sun or part sun.

Plant Care: Plant in full sun to part sun, in average, well-drained soil that stays a little moist. In hot spots, afternoon shade keeps the leaves fresh. Water regularly the first season and during dry spells. After the main bloom, the stems can flop. Cut the plant back hard. It quickly makes a fresh mound of leaves and sometimes a few more flowers. Divide every few years in spring or fall to keep it vigorous.

History: 'Johnson's Blue' is a hybrid between the European meadow cranesbill, Geranium pratense, and Geranium himalayense from the Himalayas. It was selected from seedlings grown by A.T. Johnson and introduced around 1950 by B. Ruys of the Royal Moerheim Nursery in the Netherlands.

Final Thoughts: Cut a few for the table, then watch the rabbits sulk off empty-handed. BLUE MOOD, GOOD MOOD.
