Description:
BACKGROUND OF INVENTION 
     The present invention comprises a new and distinct New Guinea impatiens plant, botanically known as  Impatiens hawkeri,  and hereinafter referred to by the cultivar name ‘Balcelbupi’. 
     The new cultivar was developed by the inventor in a controlled breeding program during 1997 at Arroyo Grande, Calif. The objective of the breeding program was to develop new cultivars with numerous, large flowers, excellent basal branching and upright medium growth habit. 
     The female (seed) parent of ‘Balcelbupi’ was ‘Moorea’ (U.S. Plant Pat. No. 9,147) characterized by its compact growth habit, pure white flowers and medium green foliage. The male (pollen) parent of ‘Balcelbupi’ was the proprietary  Impatiens hawkeri  cultivar designated ‘50-4’ (non-patented) characterized by its compact habit, pink flowers and dark green foliage. ‘Balcelbupi’ was discovered and selected as a flowering plant within the progeny of the stated cross in December of 1997. 
     Asexual reproduction of the new cultivar by terminal cuttings has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and retained through successive generations of such asexual propagation. The new cultivar was asexually reproduced in Arroyo Grande, Calif. and West Chicago, Ill. 
     SUMMARY OF INVENTION 
     It was found that the cultivar of the present invention: 
     (a) Exhibits large round blush pink flowers, 
     (b) Forms dark green foliage, 
     (c) Exhibits a good basal branching character, and 
     (d) Exhibits a medium, upright mounded growth habit. 
     The new cultivar of the present invention can be compared to both its female parent ‘Moorea’ and Celebration Blush White (U.S. Plant Pat. No. 8,538). When compared to ‘Moorea’ it is found that the new cultivar has larger flowers, smaller leaves, longer internodes and shorter spur. When compared to Celebration Blush White, the new cultivar is more compact, has shorter internodes, smaller leaves and larger flowers of a darker pink color. A detailed comparison can be found in Table A, below.

     BRIEF DESCRIPTION OF THE PHOTOGRAPH 
     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. The plants were grown in a greenhouse at West Chicago, Ill., U.S.A. 
    
    
     DETAILED DESCRIPTION 
     The ‘Balcelbupi’ 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. 
     The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined on Aug. 30, 2000 between 1:00 and 1:45 p.m. under natural daylight conditions. The following measurments and describe plants ten (10) weeks old and produced from cuttings taken from stock plants and grown in 10 cm pots under greenhouse conditions comparable to those used in commercial practice while utilizing a soilless growth medium and maintaining temperatures of approximately 72° F. during the day and approximately 65° F. during the night.
