Abstract

A new and distinct cultivar of Impatiens plant named ‘Doimtamawisa’ characterized by its upright, outwardly spreading and mounding plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; freely and early flowering habit; relatively large light red and orange red bi-colored flowers with red purple-colored centers; and good garden performance.

Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DOIMTAMAWISA’.

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 ‘Doimtamawisa’.

The new Impatiens plant is a product of a planned breeding program conducted by the Inventors in Koka, Ethiopia and Rheinberg, Germany. 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 Inventors in November, 2012 in Koka, Ethiopia of Impatiens hawkeri ‘Tamar Orange Orchid’, disclosed in U.S. Plant Pat. No. 18,682, as the female, or seed, parent with Impatiens hawkeri ‘Duemagwis’, disclosed in U.S. Plant Pat. No. 26,782, as the male, or pollen, parent. The new Impatiens plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in April, 2013.

Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2013 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 ‘Doimtamawisa’. These characteristics in combination distinguish ‘Doimtamawisa’ as a new and distinct Impatiens plant:

    • 1. Upright, outwardly spreading and mounding plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Dark green-colored leaves.
    • 5. Freely and early flowering habit.
    • 6. Relatively large light red and orange red bi-colored flowers with red purple-colored centers.
    • 7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the female parent, ‘Tamar Orange Orchid’. Plants of the new Impatiens differ primarily from plants of ‘Tamar Orange Orchid’ in the following characteristics:

    • 1. Plants of the new Impatiens are not as vigorous as plants of ‘Tamar Orange Orchid’.
    • 2. Plants of the new Impatiens have larger flowers than plants of ‘Tamar Orange Orchid’.
    • 3. Plants of the new Impatiens flower later than plants of ‘Tamar Orange Orchid’.
    • 4. Plants of the new Impatiens and ‘Tamar Orange Orchid’ differ in flower color as plants of ‘Tamar Orange Orchid’ have dark orange and light pink bi-colored flowers.

Plants of the new Impatiens can be compared to plants of the male parent, ‘Duemagwis’. Plants of the new Impatiens differ primarily from plants of ‘Duemagwis’ in the following characteristics:

    • 1. Plants of the new Impatiens flower earlier than plants of ‘Duemagwis’.
    • 2. Plants of the new Impatiens have larger flowers than plants of ‘Duemagwis’.
    • 3. Plants of the new Impatiens and ‘Duemagwis’ differ in flower color as plants of ‘Duemagwis’ have light red-colored flowers.

Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Timor’, disclosed in U.S. Plant Pat. No. 9,144. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Timor’ in the following characteristics:

    • 1. Plants of the new Impatiens and ‘Timor’ differ in leaf color as leaves of plants of ‘Timor’ are medium green in color.
    • 2. Plants of the new Impatiens flower later than plants of ‘Timor’.
    • 3. Plants of the new Impatiens have larger flowers than plants of ‘Timor’.
    • 4. Plants of the new Impatiens and ‘Timor’ differ in flower color as plants of ‘Timor’ have bright orange-colored flowers.

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. Plants of the new Impatiens flower later than plants of ‘Duemagfi’.
    • 2. Plants of the new Impatiens have larger flowers than plants of ‘Duemagfi’.
    • 3. Plants of the new Impatiens and ‘Duemagfi’ differ in flower color as plants of ‘Duemagfi’ have light red-colored 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 ‘Doimtamawisa’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘Doimtamawisa’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the winter 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 25 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
