Geranium x ‘Johnson’s Blue’     Family: Geraniaceae

Common name: cranesbill
Zone: 4 – 9
Height: 18-24 in (45-60cm)   Spread: 18-24 in (45-60cm)
Aspect: full sun; partial shade
Soil: average; well-draining
Water: moderate

Description: An herbaceous perennial with an upright, non-clumping habit. Medium green, lobed leaves are finely cut. Masses of 2 inch (5 cm) lavender-blue flowers, flushed with reddish-pink tinge appear mid-spring through late summer.


Special Notes: A hybrid seedling selected from a crossing of Geranium himalayense and Geranium pratense. Does not set seed. However, it does grow into a fairly substantial clump within a relatively short period of time. Easy care; relatively pest and disease free. Because of loose growth habit, may need propping up. Cut back severely after flowering to tidy up; fresh new leaves will appear and perhaps a second flush of blooms. Fairly drought tolerant. Deer and rabbit resistant.
