New Guinea plant named ‘Fidimppi’

Abstract

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

Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘Fidimppi’.

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 ‘Fidimppi’.

The new Impatiens plant 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 plants with freely flowering habit and large attractive flowers.

The new Impatiens plant 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 AMI 081120, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number AMI 081130, not patented, 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 2005.

Asexual reproduction of the new Impatiens by vegetative cuttings in a controlled environment in De Lier, The Netherlands since 2006, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Impatiens plant have 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 ‘Fidimppi’. These characteristics in combination distinguish ‘Fidimppi’ 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 intense dark pink-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 flower later than plants of the female parent selection.
  • 2. Flowers of plants of the new Impatiens do not fade with development whereas flowers of plants of the female parent selection fade with development.

Plants of the new Impatiens can be compared to plants of the male parent selection. Plants of the new Impatiens differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Impatiens are more vigorous than plants of the male parent selection.
  • 2. Plants of the new Impatiens have smaller flowers than plants of the male parent selection.

Plants of the new Impatiens can be compared to plants of Impatiens ‘Fitam Light Pink’, disclosed in U.S. Plant Pat. No. 15,223. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Impatiens differed from plants of ‘Fitam Light Pink’ in the following characteristics:

• • 1. Plants of the new Impatiens were more vigorous than plants of ‘Fitam Light Pink’.
  • 2. Flowers of plants of the new Impatiens were darker pink in color than plants of ‘Fitam Light Pink’.
