STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE
The Inventor and Applicant/Assignee assert that no publications nor 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 Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception 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 ‘Dongirolcoca’.
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 freely branching and 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, 2017 in Koka, Ethiopia of a proprietary selection of Impatiens hawkeri identified as code number NN15-571729-001, not patented, as the female, or seed, parent with Impatiens hawkeri ‘Rococo Josephine 2016’, 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, Calif. in April, 2018.
Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2018 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 ‘Dongirolcoca’. These characteristics in combination distinguish ‘Dongirolcoca’ as a new and distinct Impatiens plant:
    • 1. Relatively compact, upright to outwardly spreading and uniformly mounding plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Glossy and dark green-colored leaves.
    • 5 Freely flowering habit.
    • 6. Medium to large ruffled flowers that are light purplish pink in color.
    • 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 compact than plants of the female parent selection.
    • 2. Leaves of plants of the new Impatiens are lighter green in color than leaves of plants of the female parent selection.
    • 3. Flowers of plants of the new Impatiens are more ruffled and undulating than flowers of plants of the female parent selection.
    • 4. Flowers of plants of the new Impatiens are light purplish pink in color whereas flowers of plants of the female parent selection are lavender in color.
Plants of the new Impatiens can be compared to plants of the male parent, ‘Rococo Josephine 2016’. Plants of the new Impatiens differ primarily from plants of ‘Rococo Josephine 2016’ in the following characteristics:
    • 1. Flowers of plants of the new Impatiens are more ruffled and undulating than flowers of plants of ‘Rococo Josephine 2016’.
    • 2. Flowers of plants of the new Impatiens are light purplish pink in color whereas flowers of plants of ‘Rococo Josephine 2016’ are lavender pink in color.
Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Dongirolsal’, disclosed in U.S. Plant patent application Ser. No. 17/230,915 filed concurrently. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Dongirolsal’ in flower color as flowers of plants of the new Impatiens are light purplish pink in color whereas flowers of plants of ‘Dongirolsal’ are salmon pink in color.
Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Kironanete’, disclosed in U.S. Plant Pat. No. 26,753. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Kironanete’ in the following characteristics:
    • 1. Plants of the new Impatiens have larger flowers than plants of ‘Kironanete’.
    • 2. Flowers of plants of the new Impatiens are more ruffled than flowers of plants of ‘Kironanete’.
    • 3. Flowers of plants of the new Impatiens are light purplish pink in color whereas flowers of plants of ‘Kironanete’ are dark cherry red in color.
Plants of the new Impatiens can also be compared to plants of Impatiens hawkeri ‘Duemagpin’, disclosed in U.S. Plant Pat. No. 25,035. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Duemagpin’ in the following characteristics:
    • 1. Plants of the new Impatiens are more compact than and not as vigorous as plants of ‘Duemagpin’.
    • 2. Leaves of plants of the new Impatiens are lighter green in color than leaves of plants of ‘Duemagpin’.
    • 3. Flowers of plants of the new Impatiens are more ruffled than flowers of plants of ‘Duemagpin’.
    • 4. Flowers of plants of the new Impatiens are light purplish pink in color whereas flowers of plants of ‘Duemagpin’ are soft pink in color.
