Abstract

A new and distinct cultivar of Ivy Geranium plant named ‘Duearthemia’, characterized by its upright and outwardly spreading plant habit; freely basal branching habit; freely and early flowering habit; and dark red-colored double flowers.

Description

Botanical classification/cultivar denomination: Pelargonium peltatum cultivar Duearthemia.
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 ‘Duearthemia’.
The new Ivy Geranium is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program was to develop new freely-flowering Ivy Geraniums with attractive flower and foliage colors.
The new Ivy Geranium originated from a cross-pollination made by the Inventor in May, 2000, of a proprietary selection of Pelargonium peltatum identified as code number F-02-01, not patented, as the female, or seed, parent with a proprietary selection of Pelargonium peltatum identified as code number F-09-14, not patented, as the male, or pollen, parent. The cultivar Duearthemia was discovered and selected by the Inventor as a flowering plant within the progeny from this cross in a controlled environment in Rheinberg, Germany in April, 2002.
Asexual reproduction of the new cultivar by terminal vegetative cuttings at Rheinberg, Germany since June, 2002 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 ‘Duearthemia’. These characteristics in combination distinguish ‘Duearthemia’ as a new cultivar and distinguish it from other known Ivy Geranium cultivars:
    • 1. Upright and outwardly spreading plant habit.
    • 2. Freely basal branching habit.
    • 3. Freely and early flowering habit.
    • 4. Dark red-colored double flowers.
Compared to plants of the female parent selection, plants of the new Ivy Geranium are more compact and more freely flowering.
Compared to plants of the male parent selection, flowers of the new Ivy Geranium are more intense in color.
The new Ivy Geranium can be compared to plants of the cultivar Barock, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Ivy Geranium differed from plants of the cultivar Barock in the following characteristics:
    • 1. Plants of the new Ivy Geranium were shorter than plants of the cultivar Barock.
    • 2. Leaves of the new Ivy Geranium were shorter than leaves of plants of the cultivar Barock.
    • 3. Plants of the new Ivy Geranium were more freely flowering than plants of the cultivar Barock.
    • 4. Flowers of plants of the new Ivy Geranium were more red in color than flowers of plants of the cultivar Barock.
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. 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.
The photograph comprises a side perspective view of typical flowering plants of ‘Duearthemia’ grown in a container.
 DETAILED BOTANICAL DESCRIPTION
The cultivar Duearthemia 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 aforementioned photograph, following observations and measurements describe plants grown in Rheinberg, Germany during the spring under commercial practice in a glass-covered greenhouse with day and night temperatures about 18° C., and light levels about 4,500 foot-candles. Plants were grown with three plants per container. Plants were pinched about three weeks after planting. Plants were about eight weeks from unrooted cuttings when the photograph and the detailed botanical description were taken.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 edition, except where general terms of ordinary dictionary significance are used.
