Abstract

A new and distinct cultivar of Campanula plant named ‘Allgentitwist’ characterized by its broadly upright plant habit; freely basal branching habit; freely and uniformly flowering habit; campanulate-shaped flowers with violet-colored petals and white-colored sepals giving a bi-colored appearance; and good garden performance.

Description

Botanical designation: Campanula glomerata.
Cultivar denomination: ‘ALLGENTITWIST’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula glomerata and hereinafter referred to by the name ‘Allgentitwist’.
The new Campanula is a product of a planned breeding program conducted by the Inventor in Cuijk, The Netherlands. The objective of the breeding program is to create new freely flowering Campanula plants with attractive inflorescences and good garden performance.
The new Campanula plant originated from an open-pollination in Cuijk, The Netherlands during June, 2009 of a proprietary selection of Campanula glomerata identified as code number 6-3-21, not patented, as the female, or seed, parent with an unknown selection of Campanula glomerata as the male, or pollen, parent. The new Campanula was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination grown in a controlled outdoor nursery in Cuijk, The Netherlands in June, 2011.
Asexual reproduction of the new Campanula plant by tissue culture in The Netherlands, since July, 2011 has shown that the unique features of this new Campanula plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Campanula have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Allgentitwist’. These characteristics in combination distinguish ‘Allgentitwist’ as a new and distinct Campanula plant:
    • 1. Broadly upright plant habit.
    • 2. Freely basal branching habit.
    • 3. Freely and uniformly flowering habit.
    • 4. Campanulate-shaped flowers with violet-colored petals and white-colored sepals giving a bi-colored appearance.
    • 5. Good garden performance.
Plants of the new Campanula differ from plants of the female parent selection in the following characteristics:
    • 1. Flowers of plants of the new Campanula have violet-colored petals whereas flowers of plants of the female parent selection have blue-colored petals.
    • 2. Flowers of plants of the new Campanula have white-colored sepals whereas flowers of plants of the female parent selection have green-colored sepals.
Plants of the new Campanula can be compared to plants of Campanula glomerata ‘Allgentibl’, disclosed in U.S. Plant patent application Ser. No. 13/694,021. Plants of the new Campanula differ primarily from plants of ‘Allgentibl’ in the following characteristics:
    • 1. Flowers of plants of the new Campanula had violet-colored petals whereas flowers of plants of ‘Allgentibl’ had purple violet-colored petals.
    • 2. Flowers of plants of the new Campanula had white-colored sepals whereas flowers of plants of ‘Allgentibl’ had green-colored sepals.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Campanula plant 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 accurately describe the colors of the new Campanula plant.
The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Allgentitwist’ grown in a container.
The photograph on the second sheet is a close-up view of typical leaves of ‘Allgentitwist’.
The photograph on the third sheet is a close-up view of typical developing inflorescences of ‘Allgentitwist’.
The photograph on the fourth sheet is a close-up view of typical developed inflorescences of ‘Allgentitwist’.
 DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and following description were grown during the early summer in an outdoor nursery in Cuijk, The Netherlands and under cultural practices typical of commercial production conditions.

During the production of the plants, day temperatures ranged from 15° C. to 28° C. and night temperatures ranged from 6° C. to 18° C. Plants were two years old when the photographs and description were taken.
