Description

Botanical designation: Impatiens hawkeri.
Cultivar denomination: ‘DONGIPETWHI’.
STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR AND APPLICANT
The Inventor and Applicant assert that no sales, publications or advertisements relating to sales, offers for sale or public distribution 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 the Applicant. Inventor and Applicant claim a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure 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 ‘Dongipetwhi’.
The new Impatiens plant is a product of a planned breeding program conducted by the Inventor in Koka, Ethiopia and Encinitas, Calif. The objective of the breeding program is to create new 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, 2015 in Koka, Ethiopia of Impatiens hawkeri ‘Rokoko Blanca’, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number NN12-005909-002, 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, Calif. in April, 2016.
Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2016 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 ‘Dongipetwhi’. These characteristics in combination distinguish ‘Dongipetwhi’ as a new and distinct Impatiens plant:
    • 1. Upright to outwardly spreading and uniformly mounding plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Glossy and dark green to dark greyed green-colored leaves.
    • 5. Freely flowering habit.
    • 6. Large flowers with cordate-shaped petals that are bright white in color.
    • 7. Good garden performance.
Plants of the new Impatiens can be compared to plants of the female parent, ‘Rokoko Blanca’. Plants of the new Impatiens differ primarily from plants of ‘Rokoko Blanca’ in the following characteristics:
    • 1. Plants of the new Impatiens are more vigorous than and not as compact as plants of ‘Rokoko Blanca’.
    • 2. Plants of the new Impatiens have slightly smaller flowers than plants of ‘Rokoko Blanca’.
    • 3. Flower margins of plants of the new Impatiens are not undulate whereas flower margins of plants of ‘Rokoko Blanca’ are undulate.
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 more vigorous than and not as compact as plants of the male parent selection.
    • 2. Plants of the new Impatiens flower earlier than plants of the male parent selection.
    • 3. Plants of the new Impatiens have larger flowers than plants of the male parent selection.
Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Moorea’, disclosed in U.S. Plant Pat. No. 9,147. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Moorea’ in the following characteristics:
    • 1. Plants of the new Impatiens are more vigorous than and not as compact as plants of ‘Moorea’.
    • 2. Plants of the new Impatiens have broader flower petals than plants of ‘Moorea’.
    • 3. Flowers of plants of the new Impatiens are brighter white in color than flowers of plants of ‘Moorea’.
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 of 2) is a side perspective view of a typical flowering plant of ‘Dongipetwhi’ grown in a container.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flowering plant of ‘Dongipetwhi’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the summer and early autumn in 16.5-cm containers in a polyethylene-covered greenhouse in Encinitas, Calif. and under cultural practices typical of commercial New Guinea Impatiens production. During the production of the plants, day temperatures averaged 26° C., night temperatures averaged 18° C. and light levels ranged from 4,500 to 5,500 lux. Plants were 18 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2017 Edition, except where general terms of ordinary dictionary significance are used.
