New Guinea Impatiens plant named ‘Duepetbrst’

A new and distinct cultivar of Impatiens plant named ‘Duepetbrst’ characterized by its upright, outwardly spreading and mounding plant habit; freely branching habit; vigorous growth habit; dark green-colored leaves; freely and early flowering habit; large pink and orange red bi-colored flowers; and good garden performance.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New GuineaImpatiensplant, botanically known asImpatiens hawkeriand hereinafter referred to by the name ‘Duepetbrst’.

The newImpatiensplant 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 and uniform New GuineaImpatiensplants with large attractive flowers.

The newImpatiensplant originated from a cross-pollination made by the Inventor in July, 2009 in Rheinberg, Germany of a proprietary selection ofImpatienshawkeri identified as code number NO3-0021-004, not patented, as the female, or seed, parent with a proprietary selection ofImpatiens hawkeriidentified as code number N07-3046-003, not patented, as the male, or pollen, parent. The newImpatiensplant 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, 2013.

Asexual reproduction of the newImpatiensplant by terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2013 has shown that the unique features of this newImpatiensplant 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 ‘Duepetbrst’. These characteristics in combination distinguish ‘Duepetbrst’ as a new and distinctImpatiensplant:1. Upright, outwardly spreading and mounding plant habit.2. Vigorous growth habit.3. Freely branching habit.4. Dark green-colored leaves.5. Freely and early flowering habit.6. Large pink and orange red bi-colored flowers.7. Good garden performance.

Plants of the newImpatienscan be compared to plants of the female parent selection. Plants of the newImpatiensdiffer primarily from plants of the female parent selection in flower color as plants of the female parent selection have blue-colored flowers. In addition, plants of the newImpatiensare more vigorous than plants of the female parent selection.

Plants of the newImpatienscan be compared to plants of the male parent selection. Plants of the newImpatiensdiffer primarily from plants of the male parent selection in flower color as plants of the male parent selection have white and dark orange bi-colored flowers.

Plants of the newImpatienscan be compared to plants ofImpatiens hawkeri‘Neptis’, disclosed in U.S. Plant Pat. No. 10,321. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the newImpatiensdiffered primarily from plants of ‘Neptis’ in the following characteristics:1. Plants of the newImpatienswere slightly smaller than plants of ‘Neptis’.2. Plants of the newImpatienshad longer leaves than plants of ‘Neptis’.3. Plants of the newImpatienshad larger flowers than plants of ‘Neptis’.4. Plants of the newImpatiensand ‘Neptis’ differed in flower color as plants of ‘Neptis’ had red and pink bi-colored flowers.5. Plants of the newImpatienshad longer peduncles than plants of ‘Neptis’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in 10.5-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial New GuineaImpatiensproduction. During the production of the plants, night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were 16 weeks old when the photograph and description were taken.
