New Guinea Impatiens plant named ‘Tamar Dark Salmon’

Abstract

A new and distinct cultivar of New Guinea Impatiens plant named ‘Tamar Dark Salmon’, characterized by its upright, outwardly spreading and uniformly mounded plant growth habit; freely branching and freely flowering habit; dark green-colored foliage; and large rounded salmon orange-colored flowers.

Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘Tamar Dark Salmon’.

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 ‘Tamar Dark Salmon’.

The new Impatiens is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program is to develop new Impatiens cultivar with large rounded flowers and attractive foliage and flower coloration.

The new Impatiens originated from a cross-pollination made by the Inventor in 2002 with two unnamed proprietary seedling selections of Impatiens hawkeri, not patented. The cultivar Tamar Dark Salmon was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in De Lier, The Netherlands.

Asexual reproduction of the new cultivar by terminal cuttings in De Lier, The Netherlands since 2002, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Tamar Dark Salmon’. These characteristics in combination distinguish ‘Tamar Dark Salmon’ as a new and distinct Impatiens cultivar:

• • 1. Upright, outwardly spreading and uniformly mounded plant growth habit.
  • 2. Freely branching and freely flowering habit.
  • 3. Dark green-colored foliage.
  • 4. Large rounded salmon orange-colored flowers.

Plants of the new Impatiens can be compared to plants of the female parent selection. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Impatiens differed from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Impatiens flowered earlier than plants of the female parent selection.
  • 2. Plants of the new Impatiens had larger flowers than plants of the female parent selection.

Plants of the new Impatiens can be compared to plants of the male parent selection. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Impatiens differed from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Impatiens had a more uniform plant habit than plants of the male parent selection.
  • 2. Plants of the new Impatiens had larger flowers than plants of the male parent selection.

Plants of the new Impatiens can also be compared to plants of the cultivar Tamar Salmon, not patented. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Impatiens differed from plants of the cultivar Tamar Salmon in the following characteristics:

• • 1. Plants of the new Impatiens were more upright than plants of the cultivar Tamar Salmon.
  • 2. Plants of the new Impatiens and the cultivar Tamar Salmon differed in flower coloration as plants of the cultivar Tamar Salmon had lighter salmon orange-colored flowers.

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.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Tamar Dark Salmon’ grown in a container.

The photograph on the second sheet is a close-up view of typical flowers of ‘Tamar Dark Salmon’.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Tamar Dark Salmon have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown in De Lier, The Netherlands, under commercial production practice in a glass-covered greenhouse during the summer. Rooted young plants were planted in 12-cm containers and the aforementioned photographs and following observations and measurements were taken about ten weeks later. During the production of the plants, day and night temperatures averaged 20° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
