Geranium plant named ‘Duebertinostar’

Abstract

A new and distinct cultivar of Ivy Geranium plant named ‘Duebertinostar’, characterized by its compact, upright and outwardly spreading plant habit; freely basal branching habit; freely flowering habit; and light red and light pink bi-colored double flowers.

Description

Botanical denomination: Pelargonium peltatum.

Cultivar designation: ‘Duebertinostar’.

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 ‘Duebertinostar’.

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 compact and freely-flowering Ivy Geraniums with attractive flower and foliage colors.

The new Ivy Geranium is a naturally-occurring whole plant mutation of a proprietary selection of Pelargonium peltatum identified as code number E-02-05, not patented. The cultivar Duebertinostar was discovered and selected by the Inventor as a flowering plant within a population of plants of the parent selection in a controlled environment in Rheinberg, Germany in May, 2003.

Asexual reproduction of the new cultivar by terminal vegetative cuttings at Rheinberg, Germany since May, 2003 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 ‘Duebertinostar’. These characteristics in combination distinguish ‘Duebertinostar’ as a new cultivar and distinguish it from the other known Ivy Geranium cultivars:

• • 1. Upright and outwardly spreading plant habit.
  • 2. Freely basal branching habit.
  • 3. Freely flowering habit.
  • 4. Light red and light pink bi-colored double flowers.

Plants of the new Ivy Geranium differ primarily from plants of the parent selection in flower color as plants of the parent selection have light red-colored flowers.

The new Ivy Geranium can be compared to plants of the cultivar Duebertino, disclosed in U.S. Plant Pat. No. 15,751. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Ivy Geranium differed from plants of the cultivar Duebertino in the following characteristics:

• • 1. Plants of the new Ivy Geranium were shorter but broader than plants of the cultivar Duebertino.
  • 2. Plants of the new Ivy Geranium had larger leaves with longer petioles than plants of the cultivar Duebertino.
  • 3. Plants of the new Ivy Geranium had larger flowers than plants of the cultivar Duebertino.
  • 4. Plants of the new Ivy Geranium and the cultivar Duebertino differed in flower coloration as plants of the cultivar Duebertino had light red-colored flowers.

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 a typical flowering plant of ‘Duebertinostar’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Duebertinostar 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 summer 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 in 10.5 cm containers. 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.
