Patent Abstract:
A new plant variety of  Kerria japonica  characterized by White flecked variegated foliage and White and Creamy striped flowers.

Full Description:
BACKGROUND OF THE INVENTION  
         [0001]    The present invention relates to a new and distinct variety of  Kerria japonica  (L.) DC [ Corchorus japonicus  Thunb.], which was discovered as a branch sport from the species  Kerria japonica  in Saitama Prefecture, Japan. The varietal denomination of the new variety is ‘FUBUKI NISHIKI’.  
           [0002]    The genus Kerria is included in the family Rosaceae, which comprises about 100 genera and 2,000 species of herbs, shrubs and trees native mostly to China and Japan. Kerria comprises one species,  Kerria japonica  (L.) DC, native to the temperate regions of eastern Asia, which possesses desirable ornamental characteristics.  
           [0003]    [0003] Kerria japonica  is a deciduous shrub with Green leaves and glabrous branches. Leaves of the typical species are alternate, oval, long acuminate, serrated on the margins with pinnate venation. It generally has Yellow flowers.  
         SUMMARY OF THE INVENTION  
         [0004]    The new variety was discovered as a branch sport and differs from its parent by white flecked variegated foliage and White and Creamy striped flowers. Asexual reproduction of the new variety by vegetative cuttings, performed in Lewisberry, Pa. and Vacaville, Calif. have confirmed that the distinctive characteristics of the new variety are stable and transmitted to succeeding generations, and the new variety reproduces true to type.  
         COMPARISON WITH PARENTS  
         [0005]    ‘FUBUKI NISHIKI’ is distinguished from its parent and all other varieties of  Kerria japonica  of which I am aware by White flecked variegated foliage and White and Creamy marked flowers. The parent plant has completely Green foliage and Yellow flowers.
