Nemesia plant named ‘KLENE04146’

Abstract

A new and distinct cultivar of Nemesia plant named ‘KLENE04146’, characterized by its upright to somewhat outwardly spreading plant habit; freely branching habit; dense and bushy appearance; numerous large violet-colored flowers; and good garden performance.

Description

Botanical designation: Nemesia hybrid.

Cultivar denomination: ‘KLENE04146’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant, botanically known as Nemesia hybrid and referred to by the name ‘KLENE04146’.

The new Nemesia is a product of a planned breeding program conducted by the Inventor in Stuttgart, Germany. The objective of the program is to create new upright and freely branching Nemesia cultivars with attractive flowers and good garden performance.

The new Nemesia originated from an open-pollination of the Nemesia hybrid cultivar Ravello, not patented, as the female, or seed, parent with an unidentified Nemesia hybrid selection during the summer of 2002. The cultivar KLENE04146 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated open-pollination in a controlled environment in Stuttgart, Germany in May, 2003.

Asexual reproduction of the new Nemesia by terminal cuttings in a controlled environment in Stuttgart, Germany since May, 2003, has shown that the unique features of this new Nemesia are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Nemesia has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘KLENE04146’ and distinguish ‘KLENE04146’ as a new and distinct cultivar:

• • 1. Upright to somewhat outwardly spreading plant habit.
  • 2. Freely branching habit; dense and bushy appearance.
  • 3. Numerous large violet-colored flowers.
  • 4. Good garden performance.

Plants of the new Nemesia differ primarily from plants of the female parent selection in plant shape as plants of the new Nemesia are more outwardly spreading than plants of the female parent selection.

Plants of the new Nemesia can be compared to plants of the cultivar Nemo Blue, not patented. In side-by-side comparisons conducted in Stuttgart, Germany, plants of the new Nemesia differed primarily from plants of the cultivar Nemo Blue in the following characteristics:

• • 1. Plants of the new Nemesia were larger than plants of the cultivar Nemo Blue.
  • 2. Plants of the new Nemesia were more freely branching than plants of the cultivar Nemo Blue.
  • 3. Plants of the new Nemesia were more freely flowering than plants of the cultivar Nemo Blue.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Nemesia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Nemesia. The photograph comprises a side perspective view of a typical plant of ‘KLENE04146’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and averaged measurements describe plants grown in Stuttgart, Germany, in an outdoor nursery during the summer with day temperatures ranging from 20° C. to 35° C. and night temperatures ranging from 10° C. to 20° C. Plants were pinched two times. Plants were about 6.5 months old when the photograph and description were taken. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
