Title: Hosta plant named ‘Hanky Panky’

Description:
Botanical classification:  Hosta hybrida.    
   Cultivar designation: ‘Hanky Panky’. 
   BACKGROUND OF THE INVENTION 
   The present invention  Hosta  ‘Hanky Panky’, relates to a new and distinct cultivar of  Hosta,  botanically known as a  Hosta  hybrid, hereinafter referred to as ‘Hanky Panky’. 
   The inventor discovered the new cultivar, ‘Hanky Panky’, in summer of 1999 in a tissue culture lab in Waseca, Minn. ‘Hanky Panky’ originated as a sport of  Hosta  ‘Striptease’ (unpatented) that arose during micropropagation. ‘Hanky Panky’ was selected for its unique variegated leaf pattern. The spring foliage of ‘Hanky Panky’ has dark green centers and wide light green margins with a stripe of white that occurs at the junction of the center and the margin. The foliage undergoes several color and pattern changes as the season progresses and matures to a pattern having lighter green to yellow centers with a deep green area replacing the white stripe area with greyed-yellow margins. ‘Striptease’, the parent plant, differs from ‘Hanky Panky’ in having light green centers with dark margins and is similar in having the white stripe pattern between the margins and centers. 
   Asexual reproduction of the new cultivar was first accomplished by in vitro propagation in Waseca, Minn. in fall of 2002. Asexual reproduction of the new cultivar by division and tissue culture has shown that the unique features of ‘Hanky Panky’ are stable and reproduced true to type in successive generations. 
   SUMMARY OF THE INVENTION 
   The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Hanky Panky’ as a new and unique cultivar of  Hosta  as observed for a period of four years.
         1. The spring foliage of ‘Hanky Panky’ has variegated foliage with light green margins, deep green margins, and a white stripes between the centers and margins. ‘Striptease’, the parent plant has foliage with a similar white stripe pattern but with light green centers and dark green margins (reversed).   2. The foliage of ‘Hanky Panky’ changes as the season progresses with the margins and centers becoming lighter green and more yellow and deep green areas that replace the white stripe pattern in the area between the centers and the margins.   3. ‘Hanky Panky’ reaches a height of about 33 cm (13 inches), exclusive of flower scapes, and a spread of about 83 cm (33 inches) at maturity. ‘Hanky Panky’ is slightly smaller in overall dimensions to ‘Striptease’.   4. ‘Hanky Panky’ blooms for about 3 to 4 weeks from early July to late August with pale lavender flowers, similar to ‘Striptease’.       

   
     BRIEF DESCRIPTION OF THE DRAWING 
     The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new  Hosta.  The photographs were taken of mature plants of ‘Hanky Panky’ as grown outdoors in Waseca, Minn. for three years. 
       FIG. 1  was taken in June and provides an overall view of the spring foliage of the new cultivar. 
     The photograph in  FIG. 2  was taken in September and provides a view of the progression of change in variegation pattern that is present in fall. 
     The colors in the photographs are as close as possible with the photographic and printing technology utilized and combined with the color values cited in the detailed botanical description accurately describe the colors of the new  Hosta.   
   

   DETAILED BOTANICAL DESCRIPTION OF THE PLANT 
   The following is a detailed description of 4 year-old plants of the new cultivar as grown outdoors in Waseca, Minn. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
