Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Pelargonium peltatum cultivar ‘Klerotyst’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ivy Geranium plant, botanically known as Pelargonium peltatum, and hereinafter referred to by the name ‘Klerotyst’.

The new Ivy Geranium is a product of a planned breeding program conducted by the Inventor in Stuttgart, Germany. The objective of the breeding program was to develop new Ivy Geraniums with uniform growth habit, and interesting flower and foliage colors.

The new Ivy Geranium originated from a cross made by the Inventor in May, 1995 of a proprietary selection of Pelargonium peltatum identified as code number PL 808, not patented, as the female, or seed, parent with an unidentified proprietary selection of Pelargonium peltatum, not patented, as the male, or pollen, parent. The cultivar Klerotyst was discovered and selected by the Inventor as a flowering plant within the progeny from this cross in a controlled environment in Stuttgart, Germany, in June, 1996.

Asexual reproduction of the new cultivar by terminal cuttings taken at Stuttgart, Germany, since July, 1996, has shown that the unique features of this new Ivy Geranium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Klerotyst’. These characteristics in combination distinguish ‘Klerotyst’ as a new cultivar and distinguish it from other known Ivy Geranium cultivars:

1. Uniform and cascading growth habit.

2. Dark green-colored leaves with zonation pattern.

3. Light purple-colored double flowers.

Plants of the new Ivy Geranium differ primarily from plants of the parent selections in plant growth habit, leaf color and flower color.

The new Ivy Geranium is most similar in flower color to the cultivar, Amethyst, not patented. However, in side-by-side comparisons conducted in Stuttgart, Germany, plants of the new Ivy Geranium differ from plants of the cultivar Amethyst in the following characteristics:

1. Cuttings of the new Ivy Geranium are easier to propagate during the winter than cuttings of the cultivar Amethyst.

2. Plants of the new Ivy Geranium are stronger and more vigorous than plants of the cultivar Amethyst.

3. Leaves of the new Ivy Geranium have a more distinct zonation pattern than leaves of the cultivar Amethyst.

4. Plants of the new Ivy Geranium are more tolerant to rain and temperature extremes than plants of the cultivar Amethyst.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph comprises a side perspective view of four typical flowering plants of ‘Klerotyst’ that were grown for about three months in a hanging basket container. Flower and foliage colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Ivy Geranium.

DETAILED BOTANICAL DESCRIPTION

The cultivar Klerotyst has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment, such as temperature and light intensity, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants that were planted in January in 12-cm pots in Stuttgart, Germany, pinched one time about two weeks later, and grown for about three months under commercial practice in a glass-covered greenhouse with day temperatures about 18 to 22° C., night temperatures about 15 to 18° C. and light levels about 20,000 to 50,000 lux. In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
