LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED 
     
       Impatiens walleriana  
     
     VARIETY DENOMINATION 
     ‘Balfiepuna’ 
     BACKGROUND OF THE INVENTION 
     The present invention comprises a new and distinct Double Impatiens plant, botanically known as  Impatiens walleriana , and hereinafter referred to by the cultivar name ‘Balfiepuna’. 
     The new cultivar was developed by the inventor through a controlled breeding program in Elburn, Ill. The objective of the breeding program was the creation of impatiens cultivars which exhibit large, fully double flowers, are free-flowering and have a vigorous self-branching habit. 
     The female (seed) parent of ‘Balfiepuna’ was the proprietary  Impatiens walleriana  cultivar designated 573-1-3-1 (not patented) which exhibits a medium to vigorous habit and single, slightly cupped coral-rose flowers. The male (pollen) parent of ‘Balfiepuna’ was the proprietary  Impatiens walleriana  cultivar designated 3020-3-1-1 (not patented) which exhibits a vigorous loose habit, and large semi-double violet flowers. 
     Asexual reproduction of the new cultivar by two or three vegetative node stem cuttings has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and are retained through successive generations of such asexual propagation. Asexual propagation was carried out in West Chicago, Ill. 
     SUMMARY OF THE INVENTION 
     It was found that the cultivar of the present invention: 
     (a) exhibits attractive double purple flowers, 
     (b) forms dark green foliage, 
     (c) exhibits a good basal branching character and 
     (d) exhibits a upright mounded growth habit. 
     The new cultivar of the present invention can be compared to Rosebud ‘Purple Magic’ (U.S. Plant Pat. No. 8,359). In side by side comparisons it is found that the new cultivar is slightly more compact, has longer peduncles, longer leaves and darker flower color as detailed in Table 1, 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. Sheet  1  shows a close-up view of a typical flower and foliage of ‘Baliepuna’. Sheet  2  shows a side perspective view of typical flowering plant of ‘Balfiepuna’. The plants were grown in a greenhouse at West Chicago, Ill., U.S.A. 
    
    
     DETAILED DESCRIPTION 
     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. 
     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 3:00 and 3:45 p.m. under natural daylight conditions. The plants were produced from cuttings taken from stock plants and grown in a double polycarbonate covered greenhouse under 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. The plants used for data collection and measurements were grown for 8 weeks.
