Double Impatiens plant named ‘Didi Orange Two’

Abstract

A new and distinct cultivar of Double Impatiens plant named ‘Didi Orange Two’, characterized by its compact, upright, outwardly spreading and mounded plant habit; freely branching growth habit; dark green-colored leaves; freely flowering habit; and orange-colored flowers that are fully double and positioned above and beyond the foliage.

Description

Botanical designation: Impatiens walleriana.

Variety denomination: ‘Didi Orange Two’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Double Impatiens plant, botanically known as Impatiens walleriana, and hereinafter referred to by the name ‘Didi Orange Two’.

The new Double Impatiens is a product of a planned breeding program conducted by the Inventor in Andijk, The Netherlands. The objective of the breeding program was to develop new compact Double Impatiens cultivars with fully double flowers, freely branching and flowering habit, early flowering and attractive flower and foliage coloration.

The new Impatiens originated from a cross-pollination made by the Inventor in March, 2000, of a proprietary Impatiens walleriana selection identified as code number IW-622-3, not patented, as the female, or seed parent, with a proprietary Impatiens walleriana selection identified as code number IN-1791-14, not patented, as the male, or pollen parent. The cultivar Didi Orange Two was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Andijk, The Netherlands in September, 2000.

Asexual reproduction of the new cultivar by terminal cuttings taken in Andijk, The Netherlands since September, 2000, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

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

• • 1. Compact, upright, outwardly spreading and mounded plant habit.
  • 2. Freely branching growth habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Orange-colored flowers that are fully double and positioned above and beyond the foliage.

Plants of the new Impatiens differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Impatiens are more compact than plants of the female parent selection.
  • 2. Leaves of plants of the new Impatiens are dark green in color whereas leaves of plants of the female parent selection are reddish green in color.
  • 3. Plants of the new Impatiens and the female parent selection differ in flower color as plants of the female parent selection have red-colored flowers.

Plants of the new Impatiens differ primarily 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 fully double flowers whereas plants of the male parent selection have semi-double flowers.
  • 3. Plants of the new Impatiens and the male parent selection differ in flower color as plants of the male parent selection have scarlet red-colored flowers.

The new Impatiens can be compared to the Impatiens walleriana cultivar Balfiedeor, (U.S. Plant Pat. No. 13,643). However, in side-by-side comparisons conducted in Gilroy, Calif., plants of the new Impatiens differed from plants of the cultivar Balfiedeor in the following characteristics:

• • 1. Leaves of plants of the new Impatiens were darker green in color than leaves of plants of the cultivar Balfiedeor.
  • 2. Flowers of plants of the new Impatiens were slightly lighter in color than flowers of plants of the cultivar Balfiedeor.
  • 3. Sepals of plants of the new Impatiens were larger than sepals of plants of the cultivar Balfiedeor.

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 at the top of the sheet comprises a side perspective view of a flowering plant of ‘Didi Orange Two’.

The photograph at the bottom of the sheet is close-up view of typical flowers and leaves of ‘Didi Orange Two’.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Didi Orange Two 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 and following observations and measurements describe plants grown in Gilroy, Calif., under commercial practice in a fiberglass-covered greenhouse during the late spring with day temperatures about 27 to 29° C., night temperatures about 16 to 18° C. and light levels about 2,000 foot-candles. Rooted young plants were planted in containers and had been growing for about five months when the photographs and the description were taken. 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.
