plant named ‘PTDB141302’

Abstract

A new and distinct Campanula plant named ‘PTDB141302’, characterized by its compact, upright to spreading and uniformly mounding plant habit; freely flowering habit; dark violet-colored flowers; and good container and garden performance.

Description

Botanical designation: Campanula portenschlagiana.

Cultivar denomination: ‘PTDB141302’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Campanula plant, botanically known as Campanula portenschlagiana and hereinafter referred to by the cultivar name ‘PTDB141302’.

The new Campanula plant is a product of a planned breeding program conducted by the Inventor in Twello, The Netherlands. The objective of the breeding program is to create new compact and freely-flowering Campanula plants that have good container and garden performance.

The new Campanula plant originated from a cross-pollination in August, 2012 of a proprietary selection of Campanula portenschlagiana identified as code number PTDB-1200201S-PT, not patented, as the female, or seed, parent with a proprietary selection of Campanula portenschlagiana identified as code number PTDB-13001103S, 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 greenhouse environment in Twello, The Netherlands in July, 2013.

Asexual reproduction of the new Campanula plant by terminal vegetative cuttings in a controlled greenhouse environment in Twello, The Netherlands, since November, 2013, has shown that the unique features of the new Campanula plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Campanula plant 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 ‘PTDB141302’. These characteristics in combination distinguish ‘PTDB141302’ as a new and distinct Campanula plant:

• • 1. Compact, upright to spreading and uniformly mounding plant habit.
  • 2. Freely flowering habit.
  • 3. Dark violet-colored flowers.
  • 4. Good container and garden performance.

Plants of the new Campanula differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Campanula are more compact than plants of the female parent selection.
  • 2. Plants of the new Campanula flower earlier than plants of the female parent selection.

Plants of the new Campanula differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Campanula are larger than plants of the male parent selection.
  • 2. Plants of the new Campanula and the male parent selection differ in flower color as plants of the male parent selection have light purple-colored flowers.

Plants of the new Campanula can be compared to plants of Campanula portenschlagiana ‘Blue Planet’, not patented. In side-by-side comparisons conducted in Twello, The Netherlands, plants of the new Campanula differ primarily from plants of ‘Blue Planet’ in the following characteristics:

• • 1. Plants of the new Campanula are more compact and more upright than plants of ‘Blue Planet’.
  • 2. Flowers of plants of the new Campanula are darker in color than flowers of plants of ‘Blue Planet’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown in 10.5-cm containers during the spring and summer in a glass-covered greenhouse in Poeldijk, The Netherlands and under cultural practices typical of commercial Campanula production. During the production of the plants, day temperatures ranged from 18° C. to 28° C., night temperatures ranged from 14° C. to 20° C. and light levels averaged 6,000 lux. Plants were twelve weeks old when the photographs and description were taken.
