Description

Botanical designation: Pelargonium zonale.

Cultivar denomination: ‘Duetemehopi’.

BACKGROUND OF THE INVENTION

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

The new Zonal Geranium plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new vigorous Zonal Geranium plants with dark green-colored leaves and attractive flowers.

The new Zonal Geranium plant originated from a cross-pollination made by the Inventor in July, 2005 in Rheinberg, Germany of a proprietary selection of Pelargonium zonale identified as code number Z02-00005-001, not patented, as the female, or seed, parent with a proprietary selection of Pelargonium zonale identified as code number F-06-0618, not patented, as the male, or pollen, parent. The new Zonal Geranium plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2008.

Asexual reproduction of the new Zonal Geranium plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since May, 2008, has shown that the unique features of this new Zonal Geranium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Zonal Geranium have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duetemehopi’. These characteristics in combination distinguish ‘Duetemehopi’ as a new and distinct cultivar of Zonal Geranium:

• • 1. Upright to outwardly spreading plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely basal branching habit.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Semi-double dark red purple-colored flowers.
  • 7. Good garden performance.

Plants of the new Zonal Geranium differ primarily from plants of the female parent selection in flower color.

Plants of the new Zonal Geranium differ primarily from plants of the male parent selection in growth habit as plants of the new Zonal Geranium are more vigorous than plants of the male parent selection. In addition, plants of the new Zonal Geranium have darker green-colored leaves than plants of the male parent selection.

Plants of the new Zonal Geranium can be compared to plants of Pelargonium zonale ‘Flower Fairy Rose’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Zonal Geranium differed from plants of ‘Flower Fairy Rose’ in the following characteristics:

• • 1. Plants of the new Zonal Geranium were larger and more vigorous than plants of ‘Flower Fairy Rose’.
  • 2. Plants of the new Zonal Geranium had darker green-colored leaves than plants of ‘Flower Fairy Rose’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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

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 Zonal Geranium plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Duetemehopi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 10.5-cm containers in Rheinberg, Germany in a glass-covered greenhouse during the summer and under conditions which closely approximate commercial production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting. Plants had been growing for 13 weeks when the photograph and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
