plant named ‘PKMTAK3’

Abstract

A new and distinct cultivar of Campanula plant named ‘PKMTAK3’, characterized by its compact plant habit; dense and bushy plant form; vigorous growth habit; and large, purple flowers.

Description

Latin name of genus and species of the plant claimed: Campanula takesimana.

Variety denomination: ‘PKMTAK3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula takesimana, commonly known as Bellflower, and hereinafter referred to by the name ‘PKMTAK3’.

The new Campanula, ‘PKMTAK3’, is a product of a planned breeding program conducted by the inventor, Christian Hald Madsen, in Søhus, Denmark. The new Campanula originated from a cross made by the inventor in March 2009 between a proprietary selection of Campanula takesimana designated 21.01.0083 (breeder reference, unpatented) as the female parent and a proprietary selection of Campanula punctata designated 39.00.3010 (breeder reference, unpatented) as the male parent. The new Campanula ‘PKMTAK3’ was discovered and selected by the inventor as a single flowering plant within the progeny of the stated cross in a controlled environment in Søhus, Denmark. The inventor selected ‘PKMTAK3’ on the basis of its compact plant habit and purple flowers.

Asexual reproduction of the new Campanula cultivar by terminal cuttings 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

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PKMTAK3’. These characteristics in combination distinguish ‘PKMTAK3’ as a new and distinct cultivar:

• • 1. Compact plant habit;
  • 2. Dense and bushy plant form, mainly due to short, upright and stiff stems;
  • 3. Strong peduncles in greyed-purple and green color;
  • 4. Purple and white flowers.

Plants of the cultivar ‘PKMTAK3’ can be compared to the Campanula takesimana cultivar ‘PKMTAK2’ (U.S. plant patent application Ser. No. 13/507,208). In side-by-side comparisons conducted by the inventor in Stige, Denmark, plants of the instant cultivar ‘PKMTAK3’ and plants of the cultivar ‘PKMTAK2’ differ in the following characteristics:

• • 1. Plants of the ‘PKMTAK3’ produce flowers with a deep purple color whereas plants of ‘PKMTAK2’ produce light red-purple flowers.
  • 2. Plants of ‘PKMTAK3’ have greyed-purple peduncles whereas plants of ‘PKMTAK2’ have green peduncles.

DETAILED BOTANICAL DESCRIPTION

The new Campanula ‘PKMTAK3’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary 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 ‘PKMTAK3’ as grown under greenhouse conditions. No growth retardants were used.

The age of the ‘PKMTAK3’ plants described is about 10 months after cutting. Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 5^th edition, except where general colors of ordinary significance are used.
