Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DONGIPETRESTA’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

The Inventor and Applicant/Assignee assert that no sales, offers for sale or public distribution of the instant plant occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosures and/or sales prior to the filing date but less than one year prior to the effective filing date.

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 ‘Dongipetresta’.

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, 2018 in Koka, Ethiopia of a proprietary selection of Impatiens hawkeri identified as code number NN16-596500-001, not patented, as the female, or seed, parent with Impatiens hawkeri ‘Tamar Purple Bicolor’, disclosed in U.S. Plant Pat. No. 15,462, 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, 2019.

Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, California since June, 2019 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 ‘Dongipetresta’. These characteristics in combination distinguish ‘Dongipetresta’ as a new and distinct Impatiens plant:

    • 1. Upright to outwardly spreading and mounding plant habit.
    • 2. Moderately vigorous to vigorous growth habit.
    • 3. Freely branching habit; dense and full appearance.
    • 4. Dark red-colored leaves.
    • 5. Freely and early flowering habit.
    • 6. Medium to large-sized single-type white to light pink and red bicolored 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 upright than plants of the female parent selection.
    • 2. Plants of the new Impatiens are more vigorous than plants of the female parent selection.
    • 3. Plants of the new Impatiens have larger flowers than plants of the female parent selection.
    • 4. Flowers of plants of the new Impatiens are light pink to white and red bicolored whereas flowers of plants of the female parent selection are dark lavender and burgundy bicolored.

Plants of the new Impatiens can be compared to plants of the male parent, ‘Tamar Purple Bicolor’. Plants of the new Impatiens differ primarily from plants of ‘Tamar Purple Bicolor’ in the following characteristics:

    • 1. Plants of the new Impatiens are more upright than plants of ‘Tamar Purple Bicolor’.
    • 2. Plants of the new Impatiens flower about one week earlier than plants of ‘Tamar Purple Bicolor’.
    • 3. Flowers of plants of the new Impatiens are light pink to white and red bicolored whereas flowers of plants of ‘Tamar Purple Bicolor’ are red purple and lavender bicolored.

Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Duepetrest’, disclosed in U.S. Plant Pat. No. 11,375. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Duepetrest’ in the following characteristics:

    • 1. Plants of the new Impatiens have more upright than plants of ‘Duepetrest’.
    • 2. Plants of the new Impatiens are more vigorous than plants of ‘Duepetrest’.
    • 3. Plants of the new Impatiens have larger flowers than plants of ‘Duepetrest’.
    • 4. Flowers of plants of the new Impatiens are light pink to white and red bicolored whereas flowers of plants of ‘Duepetrest’ are soft red and light lavender bicolored.

Plants of the new Impatiens can also be compared to plants of Impatiens hawkeri ‘Dueptbus14’, disclosed in U.S. Plant Pat. No. 26,780. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Dueptbus14’ in the following characteristics:

    • 1. Plants of the new Impatiens are not as vigorous as plants of ‘Dueptbus14s’.
    • 2. Plants of the new Impatiens have larger flowers than plants of ‘Dueptbus14’.
    • 3. Flowers of plants of the new Impatiens are light pink to white and red bicolored whereas flowers of plants of ‘Dueptbus14’ are bright red and red purple bicolored.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Impatiens plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Impatiens plant.

The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘Dongipetresta’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical flower of ‘Dongipetresta’.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 16.5-cm containers in a polyethylene-covered greenhouse in Encinitas, California and under cultural practices typical of commercial New Guinea Impatiens production.
