New Guinea plant named ‘Duessporaur’

Abstract

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

Description

Botanical designation: Impatiens×hybrida.

Cultivar denomination: ‘DUESSPORAUR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens×hybrida and hereinafter referred to by the name ‘Duessporaur’.

The new Impatiens plant is a product of a planned breeding program conducted by the Inventor in Encinitas, Calif. The objective of the breeding program is to create new uniform Impatiens plants with numerous attractive flowers and good garden performance.

The new Impatiens plant is a naturally-occurring whole plant mutation of a proprietary selection of Impatiens×hybrida identified as code number NN-0028-X0000, not patented. The new Impatiens plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the parent selection in a controlled greenhouse environment in Encinitas, Calif. on Dec. 8, 2014.

Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since Jun. 12, 2015 has shown that the unique features of this new Impatiens plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Impatiens 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 ‘Duessporaur’. These characteristics in combination distinguish ‘Duessporaur’ as a new and distinct Impatiens plant:

• • 1. Upright, outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Medium green-colored leaves.
  • 5. Early and freely flowering habit.
  • 6. Dark orange-colored flowers.
  • 7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the parent selection. Plants of the new Impatiens differ primarily from plants of the parent selection in flower color as plants of the parent selection have lighter orange-colored flowers.

Plants of the new Impatiens can be compared to plants of Impatiens×hybrida ‘Misato FG3’, disclosed in U.S. Plant Pat. No. 17,662. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Impatiens differed primarily from plants of ‘Misato FG3’ in the following characteristics:

• • 1. Plants of the new Impatiens were more compact than plants of ‘Misato FG3’.
  • 2. Plants of the new Impatiens and ‘Misato FG3’ differed in leaf color as plants of ‘Misato FG3’ have darker green- colored leaves.
  • 3. Plants of the new Impatiens and ‘Misato FG3’ differed in flower color as plants of ‘Misato FG3’ have magenta-colored flowers.

Plants of the new Impatiens can also be compared to plants of Impatiens×hybrida ‘SAKIMP012’, disclosed in U.S. Plant Pat. No. 19,392. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Impatiens differed primarily from plants of ‘SAKIMP012’ in the following characteristics:

• • 1. Plants of the new Impatiens were more compact than plants of ‘SAKIMP012’.
  • 2. Plants of the new Impatiens and ‘SAKIMP012’ differed in leaf color as plants of ‘SAKIMP012’ have darker green-colored leaves.
  • 3. Plants of the new Impatiens and ‘SAKIMP012’ differed in flower color as plants of ‘SAKIMP012’ have red purple-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the winter and spring in one-gallon containers in a polyethylene-covered greenhouse in Encinitas, Calif. and under cultural practices typical of commercial New Guinea Impatiens production.
