BOTANICAL CLASSIFICATION

Impatiens walleriana

VARIETAL DENOMINATION

‘Cameo Cherry Red’

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Impatiens walleriana, known by the cultivar name ‘Cameo Cherry Red’. The new variety is a product of a planned breeding program conducted in Cartago, Costa Rica. The purpose of the breeding program was to develop compact and mounded cultivars with fully double flowers, large flower size and cherry red flowers. The new variety originated from a cross made by the Inventor of two unnamed proprietary selections of Impatiens walleriana, not patented. Comparisons between the new variety and its parents cannot be made, as the parental varieties no longer exist. The cultivar ‘Cameo Cherry Red’ was discovered and selected as a flowering plant within the progeny of the stated cross in a controlled environment in Cartago, Costa Rica. Asexual reproduction of the new cultivar by terminal cuttings has shown that the unique features of the new variety are stable and reproduced true to type in successive propagations.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Cameo Cherry Red’. Characteristics that distinguish ‘Cameo Cherry Red’ as a new and distinct cultivar from others known to the breeder include:

1) Large flower size of 5 to 5.5 cm in diameter;

2) Compact, mounded, spreading growth habit;

3) Freely branching habit;

4) Rounded leaves with dense foliage;

5) Flower remains fully double even under stressful environmental conditions; and

6) Cherry red flowers are carried above the leaf canopy and face upward.

Plants of the new variety can be compared to plants of the Impatiens walleriana cultivar ‘Balolecher’, disclosed in U.S. Plant Pat. No. 13,668. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new variety differed from plants of ‘Balolecher’ in the following characteristics:

1) Plants of the new variety had larger flowers than plants of ‘Balolecher’;

2) Plants of the new variety had flowers with a color of 52A, whereas plants of ‘Balolecher’ had flowers with a color of 53C;

3) Plants of the new variety had a stem color of 148C with a cast around the nodes of 184C, whereas plants of ‘Balolecher’ had a stem color of 147C with 184D on younger stems; and

4) Plants of the new variety had mature leaves with the underside having a color of 147C with a cast of 184D in areas, whereas plants of ‘Balolecher’ had mature leaves with the underside having a color of 148C with a cast of 184D in some areas.

Plants of the new variety can be compared to plants of the Impatiens walleriana cultivar ‘Cameo Scarlet’, disclosed in U.S. Plant Pat. No. 12,036. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new variety differed from plants of ‘Cameo Scarlet’ in the following characteristics:

1) Plants of the new variety had larger flowers than the plants of ‘Cameo Scarlet’;

2) Plants of the new variety had flowers with a color of 52A, whereas the plants of ‘Cameo Scarlet’ had flowers with a color of 44B;

3) Plants of the new variety had longer leaves than plants of ‘Cameo Scarlet’; and

4) Plants of the new variety had mature leaves with the underside having a color of 147C with a cast of 184D in areas, whereas plants of ‘Cameo Scarlet’ had mature leaves with the underside having a color of 147B.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographic drawing illustrates the new variety with the colors being as nearly true as is possible to obtain in colored illustrations of this type.

DESCRIPTION OF THE PLANT

The cultivar ‘Cameo Cherry Red’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length and light intensity. However, there is no variance in genotype.

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. Plants were grown under commercial practice during the late winter through early spring of 2003 in Lompoc, Calif., in a corrugated polycarbonate-covered greenhouse with 30% shade covering. During the production of the plants, day temperatures ranged from 21 to 24° C.; night temperatures ranged from 16 to 18° C.; and light levels ranged from 4000 to 5000 foot candles of light. Plants used in the following description were grown in 15 cm containers for about nine to ten weeks after planting rooted cuttings.
