Abstract:
A new and distinct cultivar of Impatiens plant named ‘Balpixotse’ characterized by its single, pink-colored flowers, dark green-colored foliage, compact, upright and mounded growth habit, and excellent basal branching.

Description:
Latin name of the genus and species of plant claimed:  Impatiens walleriana.    
     Variety denomination: ‘Balpixotse’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of Impatiens plant botanically known as  Impatiens walleriana  and hereinafter referred to by the cultivar name ‘Balpixotse’. 
     The new cultivar was developed by the inventor in a controlled breeding program during February 1999 at Elburn, Ill. The objective of the breeding program was to develop new Impatiens cultivars with numerous small flowers, excellent basal branching and upright compact growth habit. 
     The female (seed) parent of ‘Balpixotse’ was the proprietary  Impatiens walleriana  selection designated ‘3264-2’ (not patented) characterized by its vigorous growth habit, small, single rose-colored flowers and dark green-colored foliage. The male (pollen) parent of ‘Balpixotse’ was the proprietary  Impatiens walleriana  selection ‘3275-1’ (not patented) characterized by its compact growth habit, fully double dark purple-colored flowers and dark green-colored foliage. ‘Balpixotse’ was discovered and selected as one flowering plant within the progeny of the stated cross-pollination in November of 1999 and was initially designated PAS ‘11915-3’. 
     Asexual reproduction of the new cultivar by terminal cuttings in Elburn, Ill. and West Chicago, Ill., has demonstrated that the characteristics of the new cultivar, as herein described, reproduce true to type and are firmly fixed and retained through successive generations of such asexual propagation. 
     SUMMARY OF THE INVENTION 
     The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length without, however, any change in phenotype. 
     It was repeatedly found that the cultivar of the present invention: 
     1. Exhibits small, single pink-colored flowers, 
     2. Forms dark green-colored foliage, 
     3. Exhibits a good basal branching character, and 
     4. Exhibits a compact, upright and mounded growth habit. 
     Plants of the new cultivar differ from plants of the female parent primarily in growth habit and from plants of the male parent primarily in flower type and flower color. 
     Of the many commercially available Impatiens cultivars known to the inventor, the most similar to ‘Balpixotse’ is ‘Fify Violet’ (U.S. Plant Pat. No. 11,557). In side-by-side comparison, plants of the new cultivar differ from plants of ‘Fify Violet’ by the following characteristics: 
     1. Plants of ‘Balpixotse’ have rose pink-colored flowers whereas plants of ‘Fify Violet’ have purple-colored flowers, and 
     2. Plants of ‘Balpixotse’ have a more vigorous growth habit than plants of ‘Fify Violet’. 
    
    
     BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
     The accompanying photographs show as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balpixotse’. The plants were grown for 8 weeks in a greenhouse at West Chicago, Ill.

     FIG. 2 illustrates a close-up vies of a single flower of ‘Balpixotse’. 
    
    
     DETAILED DESCRIPTION 
     The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 1995 edition, except where general color terms of ordinary significance are used. The color values were determined on Aug. 8, 2003 between 10:00 and 11:45 a.m. under natural daylight conditions. 
     The following measurements and comparisons describe plants produced from cuttings taken from stock plants and grown under greenhouse conditions comparable to those used in commercial practice. Plants were grown in 10 cm pots for 8 weeks while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65°-75° F. during the day and approximately 55°-62° F. during the night. Greenhouse light levels were maintained at approximately 4,000-6,000 footcandles during the day.
