New Guinea Impatiens plant named ‘Applause Rose’

Abstract

A new and distinct cultivar of New Guinea Impatiens plant named ‘Applause Rose’, characterized by its large, red purple-colored flowers; freely flowering habit with flowers positioned above or beyond the foliage; mounded and compact plant habit; glossy dark green leaves; and tolerance to full sun conditions and low night temperatures.

Description

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 cultivar name Applause Rose.

The new Impatiens is a product of a planned breeding program Inventor in Lompoc, Calif. The objective of the breeding program is to develop new Impatiens cultivars with compact plant habit and interesting flower and foliage colors.

The new Impatiens originated from a cross made by the Inventor of a proprietary Impatiens hawkeri seedling selection designated as code numer 95-1107-4, not patented, as the female, or seed parent, with a proprietary Impatiens hawkeri seedling selection designated as code number 93-694-3, not patented, as the male, or pollen parent. The culitvar Applause Rose was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in controlled environment in Lompoc, Calif.

Asexual reproduction of the new cultivar by terminal cuttings taken at Lompoc, Calif., has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations. Plants of the new Impatiens differ from plants of the parent selections primarily in flower and leaf color.

SUMMARY OF THE INVENTION

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

1. Large, red purple-colored flowers.

2. Freely flowering habit with flowers positioned above or beyond the foliage.

3. Mounded and compact plant habit.

4. Glossy dark green leaves.

5. Tolerant to full sun conditons and low night temperatures.

Plants of the new Impatiens can be compared to plants of the cultivar Kiped, disclosed in U.S. Plant Pat. No. 11,475. In side-by-side comparisons conducted by the Inventor in Lompoc, Calif., plants of the new Impatiens differ from plants of the cultivar Kiped, in the following characteristics:

1. Plants of the new Impatiens have longer and broader leaves than plants of the culivar Kiped.

2. Plants of the new Impatiens are more freely flowering than plants of the cultivar Kiped.

3. Plants of the new Impatiens have larger and flatter flowers than plants of the cultivar Kiped.

4. Flower color of the new Impatiens and the cultivar Kiped differ slightly, 58B and 54A, respectively.

5. Peduncles of the new Impatiens are lighter in color than peduncles of the cultivar Kiped.

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 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 ‘Applause Rose’ grown during the spring in Lompoc, Calif., in a 15-cm container for about 18 weeks after planting a rooted cutting.

DETAILED BOTANICAL DESCRIPTION

The cultivar Applause Rose has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, water status and/or fertility level, without, however, any variance in genotype. The following observations and measurements describe plants grown in Lompoc, Calif., during the spring, under commercial practice in a fiberglass-covered greenhouse. Plants used in the following description were grown in 15-cm containers for about 18 weeks after planting rooted cuttings. During the production period, night temperatures were maintained at 16° C. and light levels ranged from 3,000 to 4,000 foot-candles.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
