A new and distinct cultivar of New Guinea Impatiens plant named ‘Duepetbus’, characterized by its compact, upright and outwardly spreading growth habit; mounded plant habit; freely branching habit; moderately vigorous growth habit; dark green-colored leaves; freely flowering habit; large red and red purple bi-colored flowers; and good garden performance.

Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DUEPETBUS’.

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 ‘Duepetbus’.

The new New Guinea Impatiens is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact New Guinea Impatiens cultivars with large and attractive flowers.

The new New Guinea Impatiens originated from a cross-pollination made by the Inventor in May, 2003 in Rheinberg, Germany of a proprietary selection of Impatiens hawkeri identified as code number N00-0170-013, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number N96-0564-007, not patented, as the male, or pollen, parent. The new New Guinea Impatiens was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2005.

Asexual reproduction of the new New Guinea Impatiens by terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since May, 2005, has shown that the unique features of this new New Guinea Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new New Guinea Impatiens 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 ‘Duepetbus’. These characteristics in combination distinguish ‘Duepetbus’ as a new and distinct cultivar of Impatiens :

• • 1. Compact, upright and outwardly spreading growth habit; mounded plant habit.
  • 2. Freely branching habit.
  • 3. Moderately vigorous growth habit.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Large red and red purple bi-colored flowers.
  • 7. Good garden performance.

Plants of the new New Guinea Impatiens can be compared to plants of the female parent selection. Plants of the new New Guinea Impatiens differ from plants of the female parent selection primarily in flower color as plants of the female parent selection have light and dark orange bi-colored flowers.

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

• • 1. Plants of the new New Guinea Impatiens are more compact than plants of the male parent selection.
  • 2. Plants of the new New Guinea Impatiens and the male parent selection differ in flower color as plants of the male parent selection have purple-colored flowers.

Plants of the new New Guinea Impatiens can be compared to plants of Impatiens hawkeri ‘Kimpgua’, disclosed in U.S. Plant Pat. No. 10,429. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new New Guinea Impatiens differed from plants of ‘Kimpgua’ in the following characteristics:

• • 1. Plants of the new New Guinea Impatiens had darker colored stems than plants of ‘Kimpgua’.
  • 2. Plants of the new New Guinea Impatiens had shorter leaves than plants of ‘Kimpgua’.
  • 3. Plants of the new New Guinea Impatiens had larger flowers than plants of ‘Kimpgua’.
  • 4. Plants of the new New Guinea Impatiens and ‘Kimpgua’ differed in flower color as plants of ‘Kimpgua’ had purple and pink bi-colored flowers.
  • 5. Plants of the new New Guinea Impatiens s had shorter peduncles than plants of ‘Kimpgua’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new New Guinea 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 New Guinea Impatiens s. The photograph comprises a side perspective view of a typical flowering plant of ‘Duepetbus’ grown in a container.
