plant named ‘B.09.01’

Abstract

A new and distinct cultivar of Campanula plant named B.09.01, characterized by its compact upright plant habit; dense and bushy plant form; vigorous growth habit; and large, upright, violet-colored flowers.

Description

Latin name of the genus and species claimed: Campanula portenschlagiana Schult.

Variety denomination: ‘B.09.01’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula portenschlagiana Schult., common name Dalmatian Bellflower and hereinafter referred to by the code ‘B.09.01’.

The new Campanula is a product of a planned breeding program conducted by Gert Kim Jensen, in Marslev, Denmark. The new Campanula originated from a cross made in 2009 by the Inventor between a proprietary selection of Campanula portenschlagiana Schult, (unpatented, breeder reference 08.98.05) as the female parent, and the cultivar ‘CBO-1’(‘Blue Ocean’) (patented, U.S. Plant Pat. No. 21,733) as the male parent. The Inventor selected the new Campanula cultivar from the progeny of the above crossing in 2009 on the basis of its compact, upright growth, with low need for retardation and fungicides and distinctive flowering.

Asexual reproduction of the new Campanula cultivar by terminal vegetative cuttings was first performed in 2009 in Marslev, 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 new cultivar reproduces true to type.

SUMMARY OF THE INVENTION

Plants of the Campanula cultivar ‘B.09.01’ 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 ‘B.09.01’. These characteristics in combination distinguish ‘B.09.01’ as a new and distinct cultivar:

• • 1. Violet, single-bell flowers;
  • 2. Higher numbers of flowers per plant;
  • 3. Dense and bushy plant form, mainly due to more upright stems;
  • 4. Upright plant habit;
  • 5. Less need for growth retardant;

When plants of the cultivar ‘B.09.01’ are compared to plants of the parent cultivars ‘08.98.05’ (female) and ‘CBO-1’ (male), the varieties differ in the following characteristics:

• • 1. Plants of the new Campanula ‘B.09.01’ have more upright growth than plants of either parent cultivar;
  • 2. Plants of the new Campanula ‘B.09.01’ have no requirement for treatment by growth retardant, as do both parent cultivars.

Plants of the cultivar ‘B.09.01’ can be compared to plants of the Campanula portenschlagiana Schult. cultivar ‘PKMp01’ (‘Get Mee’) (patented, U.S. Plant Pat. No. 17,205). However, in side-by-side comparisons conducted by the Inventor in Marslev, Denmark, plants of the cultivar ‘B.09.01’ and the cultivar ‘GetMee’ differ in the following characteristics, it must however be mentioned that the new cultivar plant examined has not been treated with growth retardant.

• • 1. Plants of the new Campanula ‘B.09.01’ have deep violet, single bell, upright flowers compared to the blue flowers of ‘GetMee’;
  • 2. Plants of the new Campanula ‘B.09.01’ have more upright growth than plants of the cultivar ‘GetMee’;
  • 3. Plants of the new Campanula ‘B.09.01’ do not need growth retardant treatment;
  • 4. Plants of the new Campanula ‘B.09.01’ have more flowers per plant than the plants of the cultivar ‘GetMee’; and
  • 5. Plants of the new Campanula ‘B.09.01’ appear to be less susceptible to grey mold.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The patent or application file contains at least one drawing executed in color. Copies of this patent or patent application publication with color drawing(s) will be provided by the Office upon request and payment of the necessary fee.

The accompanying colored photographs 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 the new Campanula.
