Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Best performance generally occurs in moist, organically rich soils in full sun. Plants may appreciate some part afternoon shade in hot summer climates such as the St. Louis area. Tall stems may need staking or other support. Plants generally dislike hot and humid summers and are not recommended for growing south of USDA Zone 7.

Noteworthy Characteristics

Geranium pratense, commonly called meadow cranesbill, is native to northern Europe, central Asia and China. It is a clump-forming perennial that typically grows to 24-36” tall. Blue-purple flowers (each to 1 1/2” diameter) bloom in clusters (dense cymes) above the foliage from late spring to mid-summer. A sparse late summer or fall rebloom may occur in some areas if plants are cut back after the primary bloom period. Green basal leaves (3-6” wide) are deeply cut into 7-9 toothed lobes. Flowers give way to dehiscent fruits (capsules composed of several one-seeded carpels which shatter somewhat explosively at maturity expelling seed often significant distances). This species was introduced into North America with subsequent naturalization occurring over time in Canada from Newfoundland to Alberta and in the U.S. from Minnesota to New England south to Pennsylvania.

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 means growing in meadows.

‘New Dimension’ is a compact cultivar that is noted for its violet flowers and bronze purple foliage. It typically grows in a compact mound to only 12” tall and as wide. Flowers bloom from late spring to late summer, but bloom time may be shorter (late spring to early summer) in hot summer climates. Sparse late summer or fall rebloom may occur if plants are cut back after flowering. ‘New Dimension’ is a naturally occurring whole plant mutation of Geranium pratense Victor Reiter Junior strain. It was discovered in 1999 growing in a controlled environment in Vinhega, The Netherlands. It was selected on the basis of its uniquely colored flowers. U.S. Plant Patent PP15,941 was issued on September 6, 2005.
