Description

Botanical designation: Impatiens hawkeri.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

The Inventor and Applicant 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. Inventor and Applicant 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 ‘Dongipetresta 21’.

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, 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 Impatiens hawkeri ‘Kiamuna’, disclosed in U.S. Plant Pat. No. 20,983, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number NN12-003632-006, 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 Encinitas, Calif. 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 ‘Dongipetresta 21’. These characteristics in combination distinguish ‘Dongipetresta 21’ 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.
  • 4. Dark green-colored leaves.
  • 5. Freely and early flowering habit.
  • 6. Medium-sized red and light reddish pink bi-colored flowers.
  • 7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the female parent, ‘Kiamuna’. Plants of the new Impatiens differ primarily from plants of ‘Kiamuna’ in flower color as flowers of plants of the new Impatiens are red and light reddish pink bi-colored whereas flowers of plants of ‘Kiamuna’ are red and light red purple bi-colored.

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 not as vigorous as plants of the male parent selection.
  • 2. Plants of the new Impatiens flower earlier than plants of the male parent selection.
  • 3. Flowers of plants of the new Impatiens are red and light reddish pink bi-colored whereas flowers of plants of the male parent selection are bright red and light pink bi-colored.

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 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 red and light reddish pink bi-colored whereas flowers of plants of ‘Duepetrest’ are soft red and light lavender bi-colored.

Plants of the new Impatiens can also be compared to plants of Impatiens hawkeri ‘Tamar Purple Bicolor’, disclosed in U.S. Plant Pat. No. 15,462. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Tamar Purple Bicolor’ in the following characteristics:

• • 1. Plants of the new Impatiens flower about one week earlier than plants of ‘Tamar Purple Bicolor’.
  • 2. Plants of the new Impatiens flower have slightly smaller flowers than plants of ‘Tamar Purple Bicolor’.
  • 3. Flowers of plants of the new Impatiens are red and light reddish pink bi-colored whereas flowers of plants of ‘Tamar Purple Bicolor’ are red purple in color with a darker central band.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer and autumn in winter and early spring 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 25° C., night temperatures averaged 18° C. and light levels ranged from 4,000 to 4,500 lux. Plants were 13 weeks old when the photographs were taken and 17 weeks old when the description was taken.
