Abstract
A new cultivar of Polemonium plant named ‘DUNKAL’ that is characterized by its foliage that is variegated with light green, creamy white, dark green, and bright purple-pink when grown in full sun with foliage variegated with light pink rather than bright purple-pink when grown in shade, its multicolored foliage that is present on the basal leaves as well as on the cauline leaves and its abundance of large purple flowers that are bright purple when grown in full sun and slighter lighter purple in color when grown in shade.
Description
Botanical classification: Polemonium yezoense.
Variety denomination: ‘DUNKAL’.
The present invention relates to a new and distinct cultivar of Polemonium yezoense plant and will be referred to hereinafter by its cultivar name, ‘DUNKAL’. The new cultivar of Polemonium is a hardy herbaceous perennial grown for landscape use.
‘DUNKAL’ was discovered by the Inventors in summer of 2010 as a chance seedling in a seedflat planted with seeds of Polemonium yezoense ‘Purple Rain’ (not patented) in Byt Falkirk, Scotland, The United Kingdom. The male parent is therefore unknown.
Asexual reproduction of the new cultivar was first accomplished by tissue culture using meristematic tissue under the direction of the Inventor in June of 2010 in Heerhugowaard, The Netherlands. Propagation by stem cuttings and tissue culture has determined the characteristics to be stable and reproduced true to type in successive generations.
The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘DUNKAL’ as a unique cultivar of Polemonium.
-
- 1. ‘DUNKAL’ exhibits foliage that is variegated with light green, creamy white, dark green, and bright purple-pink when grown in full sun with foliage variegated with light pink rather than bright purple-pink when grown in shade.
- 2. ‘DUNKAL’ exhibits the multicolored foliage on the basal leaves as well as on the cauline leaves.
- 3. ‘DUNKAL’ exhibits an abundance of large purple flowers that are bright purple when grown in full sun and slighter lighter purple in color when grown in shade.
The female parent plant, ‘Purple Rain’, differs from ‘DUNKAL’ in having foliage that is green and tinged with reddish purple and bronze. ‘DUNKAL’ can also be compared to the Polemonium cultivars ‘Stairway to Heaven’ (U.S. Plant Pat. No. 15,187) and ‘Brise d'Anjou’ (U.S. Plant Pat. No. 9,781). Both are similar to ‘DUNKAL’ in having variegated foliage. ‘Stairway to Heaven’ differs from ‘DUNKAL’ in having foliage that is green and white and yellow margins and only a faint tinge of pink when grown in full sun, in having less flower spikes and less flowers per flower spike, and in having lighter colored flowers. ‘Brise d'Anjou’ differs from ‘DUNKAL’ in having foliage that is green with cream colored margins (lacks additional colors) and in having less flower spikes and less flowers per flower spike.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Polemonium.
The photograph in FIG. 1 were taken of plants 2 years in age as grown in a 25-cm container in full sun near Hertford, The United Kingdom. and provides a side view of ‘DUNKAL’ in early bloom before sunlight intensifies.
The photograph in FIG. 2 was taken of a plant 2 years in age as grown in a 2-liter container in Maldon, near Chelmsford, The United Kingdom and provides a close up view of the foliage emerging after overwintering.
The photograph in FIG. 3 was taken of a plant 2 years in age as grown in a 5-liter container in Maldon, near Chelmsford, The United Kingdom and provides a close up view of the flowers grown in full sun.
The photograph in FIG. 4 was taken of a plant 2 years in age as grown outdoors in a 5-liter container in Colchester, The United Kingdom and provides a view of a plant grown in mostly shade.
The colors in the photograph are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Polemonium.
The following is a detailed description of 1-year-old plants of the new cultivar as grown outdoors in 25-cm containers near Hertford, The United Kingdom, The United Kingdom. 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 2007 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
