Abstract

A new and distinct cultivar of Campanula plant named ‘PKMp02’, characterized by having compact, upright plant habit; dense and bushy plant form mainly due to more upright stems; vigorous growth habit and no need for chemical growth retardation; greater number of flowers per plant, large upright blue flowers, and no need for vernalization.

Description

Latin name of genus and species of the plant claimed: Campanula portenschlagiana.
Variety denimination: ‘PKMp02’.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula portenschlagiana Schult., commonly known as Dalmatian Bellflower, and hereinafter referred to by the name ‘PKMp02’.
The new Campanula, ‘PKMp02’, is a product of a planned breeding program conducted by the Inventors, Gert K. Jensen and Per Elmegaard Andersen, in Søhus, Denmark. The new Campanula originated from a cross made in 2001 by the Inventors between a proprietary selection of Campanula portenschlagiana Schult named ‘08.08’ (unpatented) as the female parent and a proprietary selection of Campanula portenschlagiana Schult named ‘08.98.05’ (unpatented) as the male parent. The Inventors selected the new Campanula cultivar from the progeny of the above cross in 2001 on the basis of its compact and freely flowering habit. Plants of the new Campanula are more upright, compact and more freely flowering than plants of both parental selections.
Asexual reproduction of the new cultivar by terminal cuttings taken and propagated in Søhus, Denmark, has shown that the unique features of this new Campanula are stable and reproduce true to type in many successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar ‘PKMp01’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, day length, and fertility level without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PKMp02’. These characteristics in combination distinguish ‘PKMp02’ as a new and distinct cultivar:
    • 1. Upright plant habit;
    • 2. Dense and bushy plant form, mainly due to more upright stems;
    • 3. Vigorous growth habit, and less need for chemical growth retardation;
    • 4. Large upright blue flowers;
    • 5. Greater number of flowers per plant; and
    • 6. No need for vernalization.
Side-by-side comparisons between the instant plant and the parental cultivars, ‘08.08’ and ‘08.98.05’, were conducted by the Inventors in Stige, Denmark. Plants of ‘PKMp02’ differ from the cultivars ‘08.08. and 08.98.05’ in the following characteristics:
    • 1. Plants of ‘PKMp02’ have shorter internodes and shorter leaves and more upright growth than plants of the cultivars ‘08.08’ and ‘08.98.05’.
    • 2. Plants of ‘PKMp02’ have light gray-green colored leaves with pubescence whereas plants of the cultivars ‘08.08’ and ‘08.98.05’ have green-colored leaves.
    • 3. Plants of ‘PKMp02’ have shorter flower peduncles than plants of the cultivars ‘08.08’ and ‘08.98.05’.
    • 4. Plants of ‘PKMp02’ are shorter and more compact than the plants of the cultivars ‘08.08’ and ‘08.98.05’.
    • 5. Plants of ‘PKMp02’ have more flowers per plant and larger flowers than the plants of the cultivars ‘08.08’ and ‘08.98.05’.
Of the many commercial cultivars known to the inventor, the most similar in comparison to ‘PKMp02’ are the Campanula portenschlagiana Schult. parental cultivars ‘08.08’ and ‘08.98.08’.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographic drawings illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which more accurately describe the actual colors of ‘PKMp02’.
The first photograph shows a side perspective view of a typical flowering plant of ‘PKMp02’ as grown in a 11 cm pot.
The second photograph drawing shows a top perspective view of a typical flowering plant of ‘PKMp02’ (referenced ‘08.01.13’) as grown.
The third photograph shows close-up view of a typical flower of ‘PKMp02’ (reference ‘08.01.13’) compared to a close-up view of a typical flower of the female parental cultivae, ‘08.08’.
The fourth photograph shows an top perspective view showing both buds and flowers of a typical plant of ‘PKMp02’..
