BOTANICAL CLASSIFICATION

Impatiens walleriana

VARIETAL DENOMINATON

‘Cameo Pink Chiffon’

BACKGROUND OF INVENTION

The present invention relates to a new and distinct cultivar of Impatiens walleriana, and hereinafter referred to by the varietal name ‘Cameo Pink Chiffon’. 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 interesting flower colors. The new variety originated from a cross made by the Inventor of two proprietary selections of Impatiens walleriana: IDXCCH-1 (female parent) (unpatented) and IDXCCH-4 (male parent) (unpatented). Comparisons between the new variety and its parents cannot be made, as the parental varieties no longer exist. The cultivar ‘Cameo Pink Chiffon’ 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 variety 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 Pink Chiffon’. Characteristics that distinguish ‘Cameo Pink Chiffon’ as a new and distinct cultivar include:

1) Large flower size of about 5.0 cm. in diameter;

2) Compact, mounded, spreading growth habit;

3) Freely branching habit;

4) Rounded leaves with dense foliage;

5) Time to produce a finished plant in a 10 cm. pot is 5 to 6 weeks; and

6) Pink 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 ‘Cameo Light Pink’, disclosed in U.S. Plant Pat. No. 12,037. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new variety differed from plants of the cultivar ‘Cameo Light Pink’ in the following characteristics:

1) Plants of the new variety had more petals per flower than plants of ‘Cameo Light Pink’;

2) Plants of the new variety had leaves that were longer and wider than plants of ‘Cameo Light Pink’;

3) Plants of the new variety had a stem color of 146D with a cast of 184D on the older stems, whereas plants of the cultivar ‘Cameo Light Pink’ had a stem color of 146C with a heavier cast of 184D;

4) Plants of the new variety had flowers with a color of 69A with a color of 67A at the base of the petals, whereas plants of ‘Cameo Light Pink’ had flowers with a color of 65A; and

5) Plants of the new variety had a flower bud diameter of about 15 mm., whereas plants of ‘Cameo Light Pink’ had a flower bud diameter of about 12 mm.

DETAILED BOTANICAL DESCRIPTION

The cultivar ‘Cameo Pink Chiffon’ 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.

• Propagation:
  • • Type cutting.—Terminal cuttings.
    • pi Time to initiate roots.—Summer: About 10 days at 21° C. Winter: About 12 days at 21° C.
