Botanical designation: Pelargonium×hortorum.
Cultivar denomination: ‘DUEPELTEXMEXRUB17’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Pelargonium plant, botanically known as Pelargonium×hortorum, commonly referred to as Zonal Geranium, and hereinafter referred to by the name ‘Duepeltexmexrub17’.
The new Pelargonium plant is a product of a planned breeding program conducted by the Inventor in Kako, Ethiopia and De Lier, The Netherlands. The objective of the breeding program is to create new freely-branching and freely-flowering Pelargonium plants with attractive leaf and flower coloration.
The new Pelargonium plant originated from a cross-pollination made by the Inventor in October, 2012 in Koka, Ethiopia of a proprietary selection of Pelargonium×hortorum identified as code designation PZ10-005406-008, not patented, as the female, or seed, parent with a proprietary selection of Pelargonium×hortorum identified as code designation PZ10-006703-002, not patented, as the male, or pollen, parent. The new Pelargonium 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 De Lier, The Netherlands in June, 2013.
Asexual reproduction of the new Pelargonium plant by vegetative terminal cuttings in a controlled greenhouse environment in De Lier, The Netherlands since July, 2013 has shown that the unique features of this new Pelargonium plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Pelargonium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Duepeltexmexrub17’. These characteristics in combination distinguish ‘Duepeltexmexrub17’ as a new and distinct Pelargonium plant:
- 1. Upright and rounded plant habit.
- 2. Vigorous growth habit.
- 3. Freely basal branching habit.
- 4. Dark green-colored leaves.
- 5. Early and freely flowering habit.
- 6. Semi-double red purple-colored flowers with light red purple-colored centers.
- 7. Good garden performance and high temperature tolerance.
Plants of the new Pelargonium differ primarily from plants of the female parent selection in flower petal color as plants of the female parent selection have salmon-colored flower petals with white-colored margins.
Plants of the new Pelargonium differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have hot pink-colored flowers with white-colored centers.
Plants of the new Pelargonium can be compared to plants of Pelargonium×hortorum ‘Duetemefi’, disclosed in U.S. Plant Pat. No. 21,114. In side-by-side comparisons, plants of the new Pelargonium differ primarily from plants of ‘Duetemefi’ in flower shape as flowers of plants of the new Pelargonium are more rounded and not as open as flowers of plants of ‘Duetemefi’.
Plants of the new Pelargonium can also be compared to plants of Pelargonium×hortorum ‘Duetemeby’, not patented. In side-by-side comparisons, plants of the new Pelargonium differ primarily from plants of ‘Duetemeby’ in growth habit as plants of the new Pelargonium are more freely branching and denser than plants of ‘Duetemeby’
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Pelargonium 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 Pelargonium plant.
The photograph is a side perspective view of a typical flowering plant of ‘Duepeltexmexrub17’ grown in a container.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in 25-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Zonal Geranium production. During the production of the plants, day temperatures ranged from 17° C. to 30° C., night temperatures ranged from 10° C. to 20° C. and light levels averaged 135 watt/m2. Plants were eight weeks old when the photograph was taken and 25 weeks old when the description was taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
