Mass Planting, Border Edging, General Garden Use, Container Planting, Hanging Baskets

Ornamental Features

Calliope® Large Orange Splash Geranium features bold balls of lightly-scented orange flowers at the ends of the stems from late spring to early fall. The flowers are excellent for cutting. Its tomentose round palmate leaves remain green in color throughout the season.

Planting & Growing

Calliope® Large Orange Splash Geranium will grow to be about 14 inches tall at maturity, with a spread of 20 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 16 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. This fast-growing annual will normally live for one full growing season, needing replacement the following year.

This plant does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid. It can be propagated by cuttings, however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Calliope® Large Orange Splash Geranium is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
