Geranium (Hardy Geranium or Crane’s Bill) ‘magnificum’

The vibrant dark violet-blue flowers of the Showy Geranium (Geranium x magnificum) appear to have penciled dark-blue veins. The blossoms attract butterflies and are about twice the size of most hardy geranium flowers, two inches rather than the average one inch across. Great in borders, cottage gardens or wild gardens. It is indeed “Showy” and a stand-out in any collection of crane’s-bill. This hybrid forms a mound of deeply-cut green foliage, bearing masses of large cup-shaped violet-blue flowers. Plants need to be cut back hard after blooming to encourage fresh new foliage. Often has attractive red fall color. This Geranium still rates as among the best of the blue forms.

Magnificum is exceptionally hardy and will grow in most areas of the United States. Listed as hardy in zones 3-10, it will tolerate the dry heat of the southwest, but does not like the humid heat of the southeast. Some hardy Geraniums are also notorious self-seeders, but Magnificum is a sterile hybrid that will grow only where you plant it.

Noteworthy Characteristics: Geranium x magnificum is a hybrid hardy geranium (G. ibericum x G. platypetalum). It typically grows in a clump to 18-24″ tall on generally upright stems clad with palmate, hairy, deeply-lobed (5-7 divisions), green leaves. Features five-petaled, violet blue flowers (to 1.5″ diameter) in early to mid-summer.

General Information +

Botanical: Geranium x magnificum

Common: Crane's Bill

Family: Geraniaceae

General Characteristics: Easily grown in average, dry to medium, well-drained soil in full sun to part shade. Appreciates some afternoon shade in hot, humid areas. Tolerates some drought, but prefers moist, humusy, well-drained soils, particularly in hot summer climates. Trim plants after flowering to shape and to stimulate new foliage growth. Plants tend to become leggy and/or flop with age, and in such case may be cut back to basal foliage to revitalize. Regardless of pruning technique, plants will not rebloom. G. x magnificum cultivars are sterile hybrids. Geranium x magnificum is a hybrid of two Geranium species (G. ibericum ibericum and G. platypetalum, hence the "x" between its genus and species names). Magnificum is superior to both its parents. It has a loosely mounded habit that makes it versatile in many areas of the garden. Its lush basal leaves are lobed and toothed, with an interesting texture. Tiny hairs make the leaves very soft to the touch. The intense electric violet blue flowers have intricate, darker veining and are larger (11/2" in diameter) than most hardy geraniums. Magnificum blooms profusely in late spring and summer, but its magnificence doesn't end there. In autumn, the foliage turns crimson red.

Planting/Care Instructions +

Pests or Diseases: No serious insect or disease problems. Flowering stems tend to flop, particularly when subjected to strong winds or rainstorms.

Planting Instructions: Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Easily grown in average, medium wet, well-drained soil in full sun to part shade. Tolerates some drought, but prefers and spreads best in moist, humusy soils with good drainage. Dead-heading is tedious for larger plantings and probably unnecessary. Foliage may decline after flowering in hot summer climates, at which point it may be lightly sheared back and shaped to revitalize.
