CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2024/0500 filed on Feb. 21, 2024, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. The information for the plant breeders' rights application was received directly from the Inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cotinus coggygria and will be referred to hereafter by its cultivar name, ‘Kolmagipur’. ‘Kolmagipur’ is a new cultivar grown for use as a landscape plant.

The new cultivar of Cotinus arose from a breeding program conducted by the Inventor in Boskoop, The Netherlands with the goal of developing an Cotinus cultivar with dark color foliage in combination with desirable growth habits.

The new cultivar arose from a cross made by the Inventor in Boskoop, The Netherlands in June of 2015 between Cotinus cultivars ‘Royal Purple’ (not patented) as the female parent and ‘Young Lady’ (not patented) as the male parent. The Inventor selected ‘Kolmagipur’ as a single unique plant amongst the seedlings that resulted from the above cross in July of 2018.

Asexual propagation of the new cultivar was first accomplished under the direction of the inventor by stem cuttings in August of 2018 in Boskoop, The Netherlands. Asexual propagation by stem cuttings and tissue culture using meristamic tissue has determined that the characteristics of the new cultivar 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 cultivar. These attributes in combination distinguish ‘Kolmagipur’ as a unique cultivar of Cotinus.

• • 1. ‘Kolmagipur’ exhibits dark purple colored foliage.
  • 2. ‘Kolmagipur’ exhibits straight and strong branches.
  • 3. ‘Kolmagipur’ exhibits an abundance of stems.
  • 4. ‘Kolmagipur’ exhibits small sized leaves.

The female parent of ‘Kolmagipur’ differs from ‘Kolmagipur’ in having crooked and less upright branches, foliage that is lighter purple in color, and leaves that are larger in size. The male parent of ‘Kolmagipur’ differs from ‘Kolmagipur’ in having foliage that is green in color that turns orange-red-yellow in color in fall, and leaves that are larger in size. ‘Kolmagipur’ can be compared to the Cotinus coggygria cultivars ‘Kolmarfo’ (not patented) and ‘Kolcot’ (U.S. Plant Pat. No. 14,120). ‘Kolmarfo’ is similar to ‘Kolmagipur’ in having purple colored foliage and straight branches. ‘Kolmarfo’ differs from ‘Kolmagipur’ in having larger sized leaves, foliage that is lighter purple in color, and less abundant stems. ‘Kolcot’ is similar to ‘Kolmagipur’ in having straight branches. ‘Kolcot’ differs from ‘Kolmagipur’ in having larger sized leaves that are green in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Cotinus. The plants in the photographs are 3-years in age as grown outdoors in a field in Boskoop, The Netherlands.

The photograph in FIG. 1 illustrates the overall plant habit and foliage coloration of ‘Kolmagipur’ in summer.

The photograph in FIG. 2 provides a view of the fall foliage of ‘Kolmagipur’.

The colors in the photographs are as close as possible with the digital photography techniques utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Cotinus.

DETAILED BOTANICAL DESCRIPTION
