Title: Dahlia plant named &#39;melody lizza&#39;

Description:
BACKGROUND OF THE INVENTION  
      The present invention comprises a new and distinct  Dahlia  plant, botanically known as  Dahlia hybrida  and hereinafter referred to by the cultivar name ‘Melody Lizza’.  
      The new cultivar originated as the product of the open pollination of the proprietary breeding selection designated VD-0-9, not patented, during 1997 at Lisse, The Netherlands. The new  Dahlia  was discovered and selected as a single flowering plant within the progeny of the above stated open pollination during the summer of 1998 at Lisse, The Netherlands.  
      Asexual reproduction of the new cultivar by terminal stem cuttings since 1998 at Lisse, Netherlands and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type, with all characteristics as herein described, firmly fixed and retained through successive generations of such asexual propagation.  
     SUMMARY OF THE INVENTION  
      It was repeatedly found that the cultivar of the present invention:  
      1. Forms double pink-bicolor ray florets and yellow disk florets.  
      2. Exhibits a vigorous, upright, and mounded growth habit.  
      ‘Melody Lizza’ 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 variance in genotype.  
      Plants of the new cultivar differ from plants of the female parent primarily in plant height and ray floret color.  
      Of the many  Dahlia  cultivars known to the inventor, ‘Melody Lizza’ can be compared to the cultivar ‘Melody Dixie’ (U.S. Plant Pat. No. 12,911) and the cultivar ‘Gallery Bellini’ (U.S. Pat. No. 14,162). However, in side by side comparisons, ‘Melody Lizza’ differs from ‘Melody Dixie’ in the following characteristics:  
      1. Plants of ‘Melody Lizza’ exhibit darker foliage color than do plants of ‘Melody Dixie’.  
      2. The flowers of ‘Melody Lizza’ are pink-bicolor whereas those of ‘Melody Dixie’ are cream-white in the center with lilac-purple margins.  
      3. The plant habit of ‘Melody Lizza’ is much more branching with shorter internodes than ‘Melody Dixie’ which has a more stretching habit.  
      Furthermore, in side by side comparisons ‘Melody Lizza’ differs from ‘Gallery Bellini’ in the following characteristics:  
      1. Plants of ‘Melody Lizza’ are more branching than plants of ‘Gallery Bellini’.  
      2. Plants of ‘Melody Lizza’ are taller than plants of ‘Gallery Bellini’. 
    
    
     BRIEF DESCRIPTION OF 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 for 16 weeks in a greenhouse at West Chicago, Ill.

     DETAILED BOTANICAL 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 color terms of ordinary significance are used. The color values were determined on May 21, 2003 in West Chicago, Ill. The readings were taken between 10:00 and 11:45 a.m. under natural light conditions. The plants were produced from cuttings taken from stock plants and were grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in 15 cm pots for 16 weeks while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65°-70° F. (18°-21° C.) during the day and approximately 60°-65° F. (15°-18° C.) during the night. Greenhouse light levels were maintained at approximately 4,00-7,000 footcandles during the day. Plants were pinched three weeks after planting of rooted cuttings. The following measurements and descriptions were taken at 16 weeks after planting of rooted cuttings.
