New Guinea impatiens plant named ‘Tamar Amethyst’

Abstract

A new and distinct cultivar of Impatiens plant named ‘Tamar Amethyst’, characterized by its upright and outwardly spreading growth habit; mounded plant form; freely branching habit; dark green-colored leaves; freely flowering habit; large red purple-colored flowers; and good garden performance.

Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘Tamar Amethyst’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens, botanically known as Impatiens hawkeri and hereinafter referred to by the name ‘Tamar Amethyst’.

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 create new freely-branching New Guinea Impatiens cultivars with freely flowering habit and large attractive flowers.

The new Impatiens originated from a cross-pollination made by the Inventor in De Lier, The Netherlands of a proprietary selection of Impatiens hawkeri identified as code number AM1 071000, not patented, as the female, or seed, parent with the Impatiens hawkeri cultivar Fitam Light Pink, disclosed in U.S. Plant Pat. No. 15,223, as the male, or pollen, parent. The new Impatiens was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in De Lier, The Netherlands in 2003.

Asexual reproduction of the new Impatiens by terminal cuttings in a controlled environment in De Lier, The Netherlands since 2004, 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 cultivar Tamar Amethyst has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature 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 ‘Tamar Amethyst’. These characteristics in combination distinguish ‘Tamar Amethyst’ as a new and distinct cultivar of Impatiens:

• • 1. Upright and outwardly spreading growth habit; mounded plant form.
  • 2. Freely branching habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Large red purple-colored flowers.
  • 6. Good garden performance.

Plants of the new Impatiens can be compared to plants of the female parent selection. Plants of the new Impatiens differ 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 flower earlier than plants of the female parent selection.

Plants of the new Impatiens can be compared to plants of the male parent, the cultivar Fitam Light Pink. Plants of the new Impatiens differ from plants of the cultivar Fitam Light Pink in the following characteristics:

• • 1. Plants of the new Impatiens are less vigorous than plants of the cultivar Fitam Light Pink.
  • 2. Plants of the new Impatiens and the cultivar Fitam Light Pink differ in flower color.

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

• • 1. Plants of the new Impatiens were less vigorous than plants of the cultivar Harmony Dark Lavender.
  • 2. Plants of the new Impatiens had darker-colored flowers than plants of the cultivar Harmony Dark Lavender.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Impatiens, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Impatiens. The photograph comprises a top perspective view of a typical flowering plant of ‘Tamar Amethyst’ grown in a container.
