Culture
Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Tolerates some drought, but produces most vigorous growth in moist, humusy soils with good drainage. Deadheading is tedious for larger plantings and probably unnecessary. Side stems may be removed at any time to control spread. If not deadheaded, some self-seeding may occur in ideal growing conditions. Foliage may be lightly sheared back and shaped to revitalize after flowering. This is a variable plant that is noted for having better tolerance for heat in hot summers and for cold in cold winters than most other species of geranium. Propagate by division, tip cuttings or seed.
Noteworthy Characteristics
Geranium sanguineum, commonly called bloody cranesbill or bloodred geranium, is an herbaceous, clump-forming perennial that typically grows in a mound to 9-12” tall with white-hairy trailing stems spreading over time to as much as 24” wide. It is native to Europe and Asia. It is perhaps the most common species of geranium grown in the U.S. today. Foliage consists of small, shallowly cut, dark green basal leaves and thinner, more deeply cut stem leaves. Solitary flowers (to 1 1/2” diameter) feature five unnotched magenta to purple crimson petals with darker veins. Flowers primarily bloom in May and June with a sparse but variable rebloom occurring throughout summer. After first fall frost, foliage usually turns attractive shades of red.
Genus name comes from the Greek word geranos meaning crane in reference to the fruit which purportedly resembles the head and beak of a crane.
Specific epithet comes from the Latin word sanguineus meaning blood red in reference to the flower color and red autumn leaves of the straight species.
‘Max Frei’ is a cultivar that is noted for its compact growth habit and reddish-purple flowers. It typically forms a spreading mound of foliage typically growing 4-9” tall and spreading 12-24” wide. It features 5-petaled, reddish-purple flowers and deeply-lobed, dark green leaves. Flowers bloom in late spring. Foliage often turns attractive shades of red in autumn.
Problems
No serious insect or disease problems. Some susceptibility to leaf spots and rusts.
Uses
