Abstract

A new and distinct cultivar of Campanula plant named ‘HAVPRTB709’ characterized by its compact, upright to outwardly spreading plant habit; freely branching habit; early and freely flowering habit; campanulate-shaped flowers with bright violet-colored petals; and good container and garden performance.

Description

Botanical designation: Campanula portenschlagiana.
Cultivar denomination: ‘HAVPRTB709’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula portenschlagiana, commonly known as Dalmatian Bellflower and hereinafter referred to by the name ‘HAVPRTB709’.
The new Campanula is a product of a planned breeding program conducted by the Inventor in Honselersdijk, The Netherlands. The objective of the breeding program is to create new compact and freely flowering Campanula plants with attractive flowers and resistance to Botrytis.
The new Campanula plant originated from a cross-pollination conducted by the Inventor in Honselersdijk, The Netherlands on Jul. 16, 2014 of Campanula portenschlagiana ‘Porto’, not patented, as the female, or seed, parent with a proprietary selection of Campanula portenschlagiana identified as code number 1403, not patented, as the male, or pollen, parent. The new Campanula plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment greenhouse in Honselersdijk, The Netherlands on May 19, 2015.
Asexual reproduction of the new Campanula plant by terminal cuttings in Honselersdijk, The Netherlands, since Aug. 18, 2015 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 combinations of 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 ‘HAVPRTB709’. These characteristics in combination distinguish ‘HAVPRTB709’ as a new and distinct Campanula plant:
    • 1. Compact, upright to outwardly spreading plant habit.
    • 2. Freely branching habit.
    • 3. Early and freely flowering habit.
    • 4. Campanulate-shaped flowers with bright violet-colored petals.
    • 5. Good container and garden performance.
Plants of the new Campanula differ from plants of the female parent, ‘Porto’, in the following characteristics:
    • 1. Plants of the new Campanula are more compact than plants of ‘Porto’.
    • 2. Flower color of plants of the new Campanula is more intense in color than flower color of plants of ‘Porto’.
Plants of the new Campanula differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Campanula are more compact than plants of the male parent selection.
    • 2. Plants of the new Campanula have larger flowers than plants of the male parent selection.
Plants of the new Campanula can be compared to plants of Campanula portenschlagiana ‘Addenda Intense Blue’, not patented. In side-by-side comparisons, plants of the new Campanula differ primarily from plants of ‘Addenda Intense Blue’ in the following characteristics:
    • 1. Plants of the new Campanula have longer lateral branches than plants of ‘Addenda Intense Blue’.
    • 2. Plants of the new Campanula have larger flowers than plants of ‘Addenda Intense Blue’.
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 ‘HAVPRTB709’ grown in a container.
The photograph on the second sheet is a close-up view of a typical flowering plant of ‘HAVPRTB709’.
DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and following description were grown during the winter and early spring in 11-cm containers in a glass-covered greenhouse in Honselersdijk, The Netherlands and under cultural practices typical of commercial Campanula plant production conditions. During the production of the plants, day temperatures ranged from 17° C. to 18° C., night temperatures ranged from 16° C. to 17° C. and light levels averaged 2,000 lux. Plants were ten weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
