USPP16100P2 - Campanula plant named ‘Bencamp 46’ - Google Patents

Abstract

A new and distinct cultivar of Campanula plant named ‘Bencamp 46’, characterized by its upright and outwardly spreading growth habit; small violet-colored flowers; long flowering period; and good garden performance.

Description

Botanical classification/cultivar designation: Campanula cochleariifolia×Campanula fragilis cultivar Bencamp 46.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula cochleariifolia×Campanula fragilis and hereinafter referred to by the name ‘Bencamp 46’.

The new Campanula is a product of a planned breeding program conducted by the Inventor in Gimte, Germany. The objective of the breeding program is to create new freely-flowering interspecific Campanula cultivars.

The new Campanula originated from a cross-pollination made by the Inventor in 1993 of an unnamed selection of Campanula cochleariifolia, not patented, as the female, or seed parent, with an unnamed selection of Campanula fragilis, not patented, as the male, or pollen parent. The new Campanula was discovered and selected as a single flowering plant from the resulting progeny of the stated cross-pollination by the Inventor in a controlled environment in Gimte, Germany in 1994.

Asexual reproduction of the new cultivar by cuttings in Gimte, Germany since 1994, has shown that the unique features of this new Campanula are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Bencamp 46 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and/or light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bencamp 46’. These characteristics in combination distinguish ‘Bencamp 46’ as a new and distinct cultivar:

• • 1. Upright and outwardly spreading growth habit.
  • 2. Small violet-colored flowers.
  • 3. Long flowering period.
  • 4. Good garden performance.

Plants of the new Campanula can be compared to plants of the female parent selection. Plants of the new Campanula differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Campanula are more upright than plants of the female parent selection.
  • 2. Flowers of plants of the new Campanula are more open than flowers of plants of the female parent selection.
  • 3. Plants of the new Campanula have shorter peduncles than plants of the female parent selection.

Plants of the new Campanula can be compared to plants of the male parent selection. 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 outwardly spreading than plants of the male parent selection.
  • 2. Flowers of plants of the new Campanula are larger than flowers of plants of the male parent selection.
  • 3. Plants of the new Campanula have better garden performance than plants of the male parent selection.

Plants of the new Campanula can be compared to plants of the Campanula cultivar Clips, not patented. In side-by-side comparisons conducted in Gimte, Germany, plants of the new Campanula differed from plants of the cultivar Clips in the following characteristics:

• • 1. Plants of the new Campanula were more outwardly spreading than plants of the cultivar Clips.
  • 2. Flowers of plants of the new Campanula were smaller than flowers of plants of the cultivar Clips.
  • 3. Plants of the new Campanula flowered for a longer period of time than plants of the cultivar Clips.
  • 4. Plants of the new Campanula had better garden performance than plants of the cultivar Clips.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary signigicance are used.
