Nierembergia plant named ‘KLENC06134’

Abstract

A new and distinct cultivar of Nierembergia plant named ‘KLENC06134’, characterized by its compact, upright and outwardly spreading and mounding plant habit; moderately vigorous growth habit; freely branching habit; large white-colored flowers; freely and continuous flowering habit; and good garden performance.

Description

Botanical designation: Nierembergia caerulea.

Cutlivar denomination: ‘KLENC06134’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nierembergia, botanically known as Nierembergia caerulea and hereinafter referred to by the name ‘KLENC06134’.

The new Nierembergia is a product of a planned breeding program conducted by the Inventor in Stuttgart, Germany. The objective of the breeding program was to create new compact Nierembergia cultivars that flower continuously.

The new Nierembergia originated from an open-pollination during the summer of 2003, in Stuttgart, Germany, of a proprietary selection of Nierembergia caerulea identified as code number J 3, not patented, as the female, or seed, parent with an unknown selection of Nierembergia caerulea, as the male, or pollen, parent. The new Nierembergia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Stuttgart, Germany in May, 2004.

Asexual reproduction of the new Nierembergia by vegetative cuttings in a controlled environment in Stuttgart, Germany since May, 2004, has shown that the unique features of this new Nierembergia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar KLENC06134 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘KLENC06134’. These characteristics in combination distinguish ‘KLENC06134’ as a new and distinct cultivar of Nierembergia:

• • 1. Compact, upright to outwardly spreading and mounding plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Large white-colored flowers.
  • 5. Freely and continuous flowering habit.
  • 6. Good garden performance.

Compared to plants of the female parent selection, plants of the new Nierembergia are more compact.

Plants of the new Nierembergia can also be compared to plants of the cultivar BeBop Blue, unpatented. In side-by-side comparisons conducted in Stuttgart, Germany, plants of the new Nierembergia and the cultivar BeBop Blue differed in the following characteristics:

• • 1. Plants of the new Nierembergia were more compact than plants of the cultivar BeBop Blue.
  • 2. Plants of the new Nierembergia flowered earlier than plants of the cultivar BeBop Blue.
  • 3. Plants of the new Nierembergia and the cultivar BeBop Blue differed in flower color as plants of the cultivar BeBop Blue have blue-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Nierembergia, 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 Nierembergia.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘KLENC06134’ grown in a container.

The photograph on the second sheet is a close-up view of typical flowers of ‘KLENC06134’.

DETAILED BOTANICAL DESCRIPTION
