GERANIUM x magnificum 'Rosemoor'

Image of Geranium x magnificum 'Rosemoor'

Family

Geraniaceae

Botanical Name

GERANIUM x magnificum 'Rosemoor'

Plant Common Name

Purple Cranesbill, Rosemoor Geranium

General Description

A particularly vigorous, upright selection of Geranium x magnificum, this fuzzy-leaved cranesbill has the deeply-lobed foliage and the cerulean blooms one would expect from a hybrid of two jagged-leaved, violet-blue-flowered geraniums. The abundant blossoms come in one flush in summer and produce no seeds. This cultivar is one of several named crosses between the European natives Geranium ibericum and Geranium platypetalum.

Each densely hairy, mid-green leaf is divided into seven to nine lobes and is further edged with teeth. The leaves turn burgundy and yellow in fall. Knee-high stems rise from the thick clump of basal leaves in early or midsummer and bear clusters of round, five-petaled, violet-blue, purple-veined flowers at their tips. The stems are less "floppy" than those of some other cultivars of Geranium x magnificum.

Grow this geranium in full to partial sun in any average garden soil that is neither bone dry nor soggy. The flower stems should be staked to prevent flopping in rains and wind. Cut plants back after blooming to force fresh new growth. The sterile plants must be divided for increase. Use this lovely perennial in borders and naturalistic plantings. Interplanting it with longer-blooming plants is best as this hybrid cranesbill flowers only briefly.
