Description

Botanical designation: Impatiens hawkeri.


Cultivar denomination: ‘DONGIPETPISWI’.


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 ‘Dongipetpiswi’.


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 NN17-706685-007, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number NN17-960663-002, 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 ‘Dongipetpiswi’. These characteristics in combination distinguish ‘Dongipetpiswi’ 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. Medium to dark green-colored leaves.
    • 5. Freely and early flowering habit.
    • 6. Medium to large-sized two-tone purplish pink and light purplish pink-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 vigorous than plants of the female parent selection.
    • 2. Plants of the new Impatiens have larger flowers than plants of the female parent selection.
    • 3. Flowers of plants of the new Impatiens are purplish pink and light purplish pink in color whereas flowers of plants of the female parent selection are salmon pink 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 flower color as flowers of plants of the new Impatiens are purplish pink and light purplish pink in color whereas flowers of plants of the male parent selection are salmon pink in color.


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 are more vigorous than and not as compact as plants of ‘Duepetrest’.
    • 2. Plants of the new Impatiens have larger flowers than plants of ‘Duepetrest’.
    • 3. Flowers of plants of the new Impatiens are purplish pink and light purplish pink in color whereas flowers of plants of ‘Duepetrest’ are soft red and light lavender 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 have smaller flowers than plants of ‘Duemagwis’.
    • 2. Flowers of plants of the new Impatiens are purplish pink and light purplish pink in color whereas flowers of plants of ‘Duemagwis’ are light red in color.

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. During the production of the plants, day temperatures averaged 25C, night temperatures averaged 18C and light levels ranged from 4,000 to 4,500 lux. Plants were 16 weeks old when the photographs were taken and 17 weeks old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
