Title: Sambucus plant named ‘Jdeboer001’

Description:
Genus/species:  Sambucus nigra.    
     Varietal denomination: ‘Jdeboer001’. 
     CROSS REFERENCE TO A RELATED APPLICATION 
     This application is related to a European plant breeders&#39; rights application filed on Sep. 17, 2014, application No. 2014-2240. There have been no offers for sale anywhere in the world prior to the filing of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder&#39;s rights documents. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Sambucus nigra  and will be referred to hereafter by its cultivar name, ‘Jdeboer001’. ‘Jdeboer001’ represents a new cultivar of Elderberry, a deciduous shrub grown for landscape use. 
     ‘Jdeboer001’ was discovered by the Inventor in the May of 2000 as a chance seedling growing in his trial plot in Feanwalden, The Netherlands. The new cultivar was found growing among several different unnamed cultivars of  Sambucus , the exact parentage is therefore unknown. 
     Asexual propagation of the new cultivar was first accomplished by the Inventor by softwood stem cuttings in summer of 2000 in Feanwalden, The Netherlands. Asexual propagation of the new cultivar by softwood stem cuttings has determined that the characteristics are stable and are 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  Sambucus . These attributes in combination distinguish ‘Jdeboer001’ as a unique cultivar of  Sambucus.  
     1. ‘Jdeboer001’ exhibits an upright and spreading plant habit.   2. ‘Jdeboer001’ exhibits deeply dissected foliage that is yellow-green in color.   3. ‘Jdeboer001’ exhibits leaves that are ovate in shape.   

     ‘Jdeboer001’ can be most closely compared to the  Sambucus  cultivars ‘Walfinb’ (U.S Plant Pat. No. 26,425) and ‘SMNSRD4’ (U.S. Plant Pat. No. 26,613). ‘Walfinb’ differs from ‘Jdeboer001’ in having leaves that are longer and more elliptical in shape, and in having new foliage that is brighter gold in color. ‘SMNSRD4’ differs from ‘Jdeboer001’ in having leaves that are oblanceolate to lanceolate in shape, and in having a more mounded plant habit. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new  Sambucus . The photographs were taken of a 2 year-old plant as grown outdoors in a 19-cm container in Feanwalden, The Netherlands. 
       The photograph in  FIG. 1  provides a side view of the plant habit of ‘Jdeboer001’. 
       The photograph in  FIG. 2  provides a close-up view of the foliage of ‘Jdeboer001’. 
     
    
    
     The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new  Sambucus.
