Abstract
A new and distinct cultivar of Campanula plant named ‘PKMT02’, characterized by having upright, compact plant habit with a wide spread area; dense and bushy plant form, mainly due to short, upright and stiff stems; vigorous growth habit, but with less need for chemical growth retardation; higher number of flowers per plant; and dark violet flower color.
Description
Latin name of genus and species of the plant claimed: Campanula sp.
Variety denomination: ‘PKMT02’.
The present invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula sp., commonly known as Bellflower, and hereinafter referred to by the name ‘PKMT02’.
The new Campanula ‘PKMT02’ is a product of a planned breeding program conducted by the inventor, Gert K. Jensen, in Søhus, Denmark. The objective of the breeding program is to develop a new Campanula cultivar with compact plant form and dark violet flowers.
The new Campanula cultivar originated from a cross made in a controlled breeding program by the inventor in 2004 in Søhus, Denmark. The female or seed parent is a Campanula tubulosa cultivar ‘PKMT01’ (patented, described in U.S. Plant Pat. No. 17,226). The male or pollen parent is the unpatented wild form of Campanula carpatha. The new Campanula ‘PKMT02’ was discovered and selected by the inventor as a single flowering plant within the progeny of the stated cross in January of 2004 in a controlled environment in Søhus, Denmark. The inventor selected ‘PKMT02’ on the basis of its compact plant form, dark violet colors and freely flowering habit. Plants of ‘PKMT02’ are more upright, compact and freely flowering than plants of the original parental cultivars.
Asexual reproduction of the new Campanula cultivar by terminal cuttings was first performed in September of 2004 in Søhus, Denmark, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PKMT02’. These characteristics in combination distinguish ‘PKMT02’ as a new and distinct cultivar:
-
- 1. Upright, compact plant habit with a wide spread area;
- 2. Dense and bushy plant form, mainly due to short, upright and stiff stems;
- 3. Vigorous growth habit, but with less need for chemical growth retardation;
- 4. Higher number of flowers per plant; and
- 5. Dark violet flower color.
Side-by-side comparisons were conducted by the inventor in Søhus, Denmark, between plants of the new Campanula sp. ‘PKMT02’ and plants of the Campanula carpatha wild type. Plants of ‘PKMT02’ differ from plants of Campanula carpatha wild type in the following characteristics:
-
- 1. Plants of ‘PKMT02’ have large, dark violet, upright, single and campanulate flowers;
- 2. Plants of ‘PKMT02’ have shorter internodes, petioles, and leaves;
- 3. Plants of ‘PKMT02’ have more upright growth;
- 4. Plants of ‘PKMT02’ have shorter peduncles;
- 5. Plants of ‘PKMT02’ are shorter and more compact in shape; and
- 6. Plants of ‘PKMT02’ produce more flowers per plant.
The most similar comparison cultivar to the new Campanula sp. ‘PKMT02’ is the female parental cultivar, Campanula tubulosa ‘PKMT01’ (patented, described in U.S. Plant Pat. No. 17,226). Plants of the new Campanula sp. ‘PKMT02’ differ from plants of Campanula tubulosa ‘PKMT01’ in the following characteristics:
-
- 1. Plants of ‘PKMT02’ have more spread (25 cm) than plants of ‘PKMT01’ (20 cm);
- 2. Plants of ‘PKMT02’ have less lateral branches (about 16) which are longer (10-13 cm) and yellow-green in color (RHS 146D) than plants of ‘PKMT01’ (about 25 lateral branches which are 3-4 cm in length and green in color, RHS 138A);
- 3. Plants of ‘PKMT02’ have taller inflorescence height (9-11 cm) than plants of ‘PKMT01’ (about 5-8 cm); and
- 4. Plants of ‘PKMT02’ produce less flowers and buds per plant (150-250) than plants of ‘PKMT01’ (300-400);
- 5. Plants of ‘PKMT02’ have buds with yellow-green color (RHS 149D) whereas plants of ‘PKMT01’ have buds with green-white color (RHS 157A); and
- 6. Plants of ‘PKMT02’ produce dark violet flowers (RHS 87A) whereas plants of ‘PKMT01’ produce violet flowers (RHS 84A).
- 7. Plants of ‘PKMT02’ produce yellow-orange anthers and pollen (RHS 16C), green-yellow styles (RHS 1D), and a yellow-green ovaries (RHS N144C) whereas plants of ‘PKMT01’ produce yellow-white anthers and pollen (RHS 158B) and white styles and ovaries (RHS 155D).
The accompanying colored photographs illustrate the overall appearance of the new Campanula ‘PKMT02’, 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 ‘PKMT02’.
The new Campanula ‘PKMT02’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, day length, and fertility level without any variance in genotype.
The aforementioned photographs, together with the following observations, measurements and values describe plants of the new Campanula ‘PKMT02’ as grown in a heated and lighted, glass-covered greenhouse in Søhus, Denmark, under conditions which closely approximate those generally used in commercial practice where day temperatures in the greenhouse range from 18-20° C. and the night temperature range from 16-18° C. Ambient light levels used while growing plants of ‘PKMT02’ are +90 Wm2. Plants of ‘PKMT02’ are grown with 18 hour long day photoperiodic treatments. No growth retardants used.
The age of the ‘PKMT02’ plants described is 18 weeks old and grown in 10.5 cm pots. The photographs and descriptions were taken during the winter season when day temperatures in glass-covered greenhouse range from 18-20° C. and when night average temperatures in glass-covered greenhouse range from 16-18° C.
