Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Impatiens walleriana cultivar Balfieplos.

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 `Balfieplos`.

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

The new Impatiens originated from a cross made by the Inventor in March, 2000, of a proprietary Impatiens walleriana selection identified as 487C-2-1, not patented, as the female, or seed parent, with a proprietary Impatiens walleriana selection identified as 3032-1-1-5-2-1, not patented, as the male, or pollen parent. The cultivar Balfieplos was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Elburn, Ill.

Asexual reproduction of the new cultivar by terminal cuttings taken at Elburn, Ill. since April, 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 `Balfieplos`. These characteristics in combination distinguish `Balfieplos` as a new and distinct 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. Light pink-colored flowers that are fully double and positioned above the foliage.

Plants of the new Impatiens differ primarily from plants of the parent selections in flower color.

The new Impatiens can be compared to the Impatiens walleriana cultivar Pink Ruffle, disclosed in U.S. Plant Pat. No. 9,616. However, in side-by-side comparisons conducted in West Chicago, Ill., plants of the new Impatiens differed from plants of the cultivar Pink Ruffle in the following characteristics:

1. Plants of the new Impatiens had larger and darker green-colored leaes than plants of the cultivar Pink Ruffle.

2. Plants of the new Impatiens were more freely flowering than plants of the cultivar Pink Ruffle.

3. Flower color of plants of the new Impatiens was lighter pink than flower color of plants of the cultivar Pink Ruffle.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph 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 side perspective view of multiple flowering plants of `Balfieplos` grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Balfieplos has 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 photograph and following observations and measurements describe plants grown in West Chicago, Ill., under commercial practice in a polycarbonate-covered greenhouse with day temperatures ranging from 20 to 24°C C., night temperatures ranging from 10 to 17°C C. and light levels ranging from 4,000 to 6,000 footcandles. Rooted young plants were planted in containers and had been growing for about five to six weeks 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.
