Title: New Guinea Impatiens Plant Named ‘DONGISUSTJAZHOPI’

Applicant: Ruth Kobayashi

Filed: Concurrently with the instant application having application Ser. No. 16/873,884.

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 ‘Dongisustjazco’.

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

The new Impatiens plant is a naturally-occurring whole plant mutation of a proprietary selection of Impatiens hawkeri identified as code number NN-1539, not patented. The new Impatiens plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the mutation parent selection in a controlled greenhouse environment in Encinitas, Calif. on Dec. 20, 2017.

Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since Jul. 20, 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 ‘Dongisustjazco’. These characteristics in combination distinguish ‘Dongisustjazco’ 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. Large variegated leaves with dark green-colored marginal areas surrounding yellow-colored centers.
    • 5. Freely flowering habit.
    • 6. Large flat flowers that are vivid red in color.
    • 7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the mutation parent selection. Plants of the new Impatiens differ primarily from plants of the mutation parent selection in flower color as flowers of plants of the new Impatiens are vivid red in color whereas flowers of plants of the mutation parent selection purplish pink in color.

Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Dongisustjazhopi’, disclosed in a U.S. Plant Patent application filed concurrently having application Ser. No. 16/873,884. Plants of the new Impatiens differ primarily from plants of ‘Dongisustjazhopi’ in flower color as plants of the new Impatiens have vivid red-colored flowers whereas plants of ‘Dongisustjazhopi’ have purplish pink-colored flowers.

Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘SAKIMP008’, disclosed in U.S. Plant Pat. No. 21,014. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘SAKIMP008’ in the following characteristics:

    • 1. Plants of the new Impatiens are not as vigorous as plants of ‘SAKIMP008’.
    • 2. Leaves of plants of the new Impatiens are variegated whereas leaves of plants of ‘SAKIMP008’ are solid green in color.
    • 3. Plants of the new Impatiens and ‘SAKIMP008’ differ in flower color as flowers of plants of the new Impatiens are vivid red in color whereas flowers of plants of ‘SAKIMP008’ are salmon orange in color.

Plants of the new Impatiens can also be compared to plants of Impatiens hawkeri ‘Duemagfi’, disclosed in U.S. Plant Pat. No. 23,912. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Duemagfi’ in the following characteristics:

    • 1. Leaves of plants of the new Impatiens are variegated whereas leaves of plants of ‘Duemagfi’ are solid green in color.
    • 2. Plants of the new Impatiens have smaller flowers than plants of ‘Duemagfi’.
    • 3. Plants of the new Impatiens and ‘Duemagfi’ differ in flower color as flowers of plants of the new Impatiens are vivid red in color whereas flowers of plants of ‘Duemagfi’ are light red in color.
