Description

Botanical designation: Impatiens hawkeri.
Cultivar denomination: ‘DUEWILDRLTPI’.
CROSS-REFERENCED TO CLOSELY-RELATED APPLICATIONS
Title: New Guinea Impatiens Plant Named ‘DUEWILDRWH’
Applicant: Ruth Kobayashi
Filed: Concurrently with this application having application Ser. No. 15/732,927.
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 ‘Duewildrltpi’.
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 flowering New Guinea Impatiens plants with ruffled semi-double and double attractive flowers and good garden performance.
The new Impatiens plant originated from a cross-pollination made by the Inventor in November, 2014 in Koka, Ethiopia of a proprietary selection of Impatiens hawkeri identified as code number NN-1339, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number NN-0013, 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, 2015.
Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since June, 2015 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 ‘Duewildrltpi’. These characteristics in combination distinguish ‘Duewildrltpi’ as a new and distinct Impatiens plant:
    • 1. Moderately compact, upright, outwardly spreading and mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Dark green-colored leaves.
    • 5. Freely and early flowering habit.
    • 6. Semi to double-type blush white-colored flowers with a ruffled appearance.
    • 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. Plants of the new Impatiens and the female parent selection differ in flower color as plants of the female parent selection have white-colored flowers.
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. Flowers of plants of the new Impatiens are held above the foliar canopy whereas flowers of plants of the male parent selection are positioned within the foliar canopy.
    • 2. Plants of the new Impatiens and the male parent selection differ in flower form as plants of the male parent selection have single-type flowers (single whorl of five petals).
    • 3. Plants of the new Impatiens and the male parent selection differ in flower color as plants of the male parent selection have white-colored flowers.
Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Duewildrwh’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Impatiens differ primarily from plants of ‘Duewildrwh’ in flower color as plants of ‘Duewildrwh’ have pure white-colored flowers. In addition, plants of the new Impatiens have slightly smaller flowers than plants of ‘Duewildrwh’.
Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Duesweetwhite’, disclosed in U.S. Plant Pat. No. 13,373. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Duesweetwhite’ in the following characteristics:
    • 1. Plants of the new Impatiens are more vigorous than and not as compact as plants of ‘Duesweetwhite’.
    • 2. Plants of the new Impatiens and ‘Duesweetwhite’ differ in flower form as plants of ‘Duesweetwhite’ have single-type flowers.
    • 3. Plants of the new Impatiens and ‘Duesweetwhite’ differ in flower color as plants of ‘Duesweetwhite’ have white-colored flowers.
Plants of the new Impatiens can 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 not as vigorous as plants of ‘Duemagpin’.
    • 2. Leaves of plants of the new Impatiens have lighter green-colored leaves than plants of ‘Duemagpin’.
    • 3. Plants of the new Impatiens and ‘Duemagpin’ differ in flower form as plants of ‘Duemagpin’ have single-type flowers.
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 at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Duewildrltpi’ grown in a container.
The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘Duewildrltpi’.
