A new and distinct cultivar of Zonal Geranium plant named ‘Duevinsky’, characterized by its upright plant habit; vigorous growth habit; freely basal branching habit; freely flowering habit; large light red purple-colored semi-double flowers; and good garden performance.

BACKGROUND OF THE INVENTION

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

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 numerous attractive flowers.

The new Zonal Geranium plant originated from a cross-pollination made by the Inventor in July, 2008 in Rheinberg, Germany of a proprietary selection ofPelargonium zonaleidentified as code number F-19-022, not patented, as the female, or seed, parent with a proprietary selection ofPelargonium zonaleidentified as code number Z05-1807-002, 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, 2012.

Asexual reproduction of the new Zonal Geranium plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2012 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

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duevinsky’. These characteristics in combination distinguish ‘Duevinsky’ as a new and distinct Zonal Geranium plant:1. Upright plant habit.2. Vigorous growth habit.3. Freely basal branching habit.4. Freely flowering habit.5. Large light red purple-colored semi-double flowers.6. Good garden performance.

Plants of the new Zonal Geranium differ primarily from plants of the female parent selection in flower color as plants of the new Zonal Geranium have lighter red purple-colored flowers than plants of the female parent selection.

Plants of the new Zonal Geranium differ primarily from plants of the male parent selection in leaf color as plants of the new Zonal Geranium have lighter green-colored leaves than plants of the male parent selection.

Plants of the new Zonal Geranium can be compared to plants of thePelargonium zonale‘Pacbla’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Zonal Geranium differed primarily from plants of ‘Pacbla’ in the following characteristics:1. Plants of the new Zonal Geranium were shorter than plants of ‘Pacbla’.2. Plants of the new Zonal Geranium had larger leaves than plants of ‘Pacbla’.3. Plants of the new Zonal Geranium had larger flowers than plants of ‘Pacbla’.4. Plants of the new Zonal Geranium and ‘Pacbla’ differed slightly in flower color.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercialPelargoniumproduction. 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 and were 13 weeks old when the photograph and the description were taken.
