Abstract

A new and distinct cultivar of Impatiens plant named ‘Dongipetfir 23’ characterized by its relatively compact, upright to outwardly spreading and mounding plant habit; moderately vigorous growth habit; freely branching habit; dense and full appearance; dark green-colored leaves; freely and early flowering habit; medium-sized single-type reddish orange-colored flowers; and good garden performance.

Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DONGIPETFIR 23’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri and hereinafter referred to by the name ‘Dongipetfir 23’.

The new Impatiens plant is a product of a planned breeding program conducted by the Inventor in Koka, Ethiopia and Encinitas, California. The objective of the breeding program is to create new freely-branching, early and freely flowering New Guinea Impatiens plants with large attractive flowers and good garden performance.

The new Impatiens plant originated from a cross-pollination made by the Inventor in November, 2019 in Koka, Ethiopia of a proprietary selection of Impatiens hawkeri identified as code number NN17-679683-011, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number NN17-604538-002, not patented, as the male, or pollen, parent. The new Impatiens 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 Encinitas, California in April, 2020.

Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, California since June, 2020 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, daylight 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 ‘Dongipetfir 23’. These characteristics in combination distinguish ‘Dongipetfir 23’ as a new and distinct Impatiens plant:

• • 1. Relatively compact, upright to outwardly spreading and mounding plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit; dense and full appearance.
  • 4. Dark green-colored leaves.
  • 5. Freely and early flowering habit.
  • 6. Medium-sized single-type reddish orange-colored flowers.
  • 7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the female parent selection. Plants of the new Impatiens differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Impatiens are more mounding than and not as spreading as plants of the female parent selection.
  • 2. Flowers of plants of the new Impatiens are reddish orange in color whereas flowers of plants of the female parent selection are orange in color.

Plants of the new Impatiens can be compared to plants of the male parent selection. Plants of the new Impatiens differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Impatiens are not as vigorous as plants of the male parent selection.
  • 2. Plants of the new Impatiens are more mounding than and not as spreading as plants of the male parent selection.
  • 3. Plants of the new Impatiens have smaller flowers than plants of the male parent selection.
  • 4. Flowers of plants of the new Impatiens are reddish orange in color whereas flowers of plants of the male parent selection are orange in color.

Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Timor’, disclosed in U.S. Plant Pat. No. 9,144. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Timor’ in the following characteristics:

• • 1. Plants of the new Impatiens have larger flowers than plants of ‘Timor’.
  • 2. Flowers of plants of the new Impatiens are reddish orange in color whereas flowers of plants of ‘Timor’ are bright orange in color.

Plants of the new Impatiens can also be compared to plants of Impatiens hawkeri ‘Duemagwis’, disclosed in U.S. Plant Pat. No. 26,782. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Duemagwis’ in the following characteristics:

• • 1. Plants of the new Impatiens are more mounding than plants of ‘Duemagwis’.
  • 2. Plants of the new Impatiens have smaller flowers than plants of ‘Duemagwis’.
  • 3. Flowers of plants of the new Impatiens are reddish orange in color whereas flowers of plants of ‘Duemagwis’ are light red in color.
