Diascia plant named ‘KLEDB06039’

Abstract

A new and distinct cultivar of Diascia plant named ‘KLEDB06039’ characterized by its vigorous growth habit; freely branching habit; freely flowering habit; and large violet blue-colored flowers.

Description

Botanical designation: Diascia×hybrida.

Cultivar denomination: ‘KLEDB06039’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Diascia, botanically known as Diascia×hybrida, and hereinafter referred to by the name ‘KLEDB06039’.

The new Diascia is a product of a planned breeding program conducted by the Inventor in Stuttgart, Germany The objective of the breeding program is to create new compact Diascia cultivars with uniform plant habit, large flowers and attractive flower colors.

The new Diascia originated from a cross-pollination made by the Inventor in Stuttgart, Germany in June, 2004 of a proprietary selection of Diascia×hybrida identified as code number X 075, not patented, as the female, or seed, parent with a proprietary selection of Diascia×hybrida identified as code number X 140, not patented, as the male, or pollen, parent. The cultivar KLEDB06039 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Stuttgart, Germany in May, 2005.

Asexual reproduction of the new Diascia by terminal cuttings in a controlled environment in Stuttgart, Germany since September, 2005, has shown that the unique features of this new Diascia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar KLEDB06039 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 ‘KLEDB06039’. These characteristics in combination distinguish ‘KLEDB06039’ as a new and distinct cultivar of Diascia:

• • 1. Vigorous growth habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Large violet blue-colored flowers.

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

• • 1. Plants of the new Diascia are more vigorous than plants of the female parent selection.
  • 2. Plants of the new Diascia have larger flowers than plants of the female parent selection.
  • 3. Plants of the new Diascia and the female parent selection differ in flower color as plants of the female parent selection have pinkish blue-colored flowers.

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

• • 1. Plants of the new Diascia have larger flowers than plants of the male parent selection.
  • 2. Plants of the new Diascia and the male parent selection differ in flower color as plants of the male parent selection have bluish pink-colored flowers.

Plants of the new Diascia can be compared to plants of the Diascia×hybrida cultivar Darea Deep Salmon, not patented. In side-by-side comparisons conducted in Stuttgart, Germany, plants of the new Diascia differed from plants of the cultivar Darea Deep Salmon in the following characteristics:

• • 1. Plants of the new Diascia were not as compact as plants of the cultivar Darea Deep Salmon.
  • 2. Flowers of plants of the new Diascia and the cultivar Darea Deep Salmon differed in flower color as plants of the cultivar Darea Deep Salmon had dark salmon-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Diascia, 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 Diascia. The photograph comprises a close-up view of a typical flowering plant of ‘KLEDB06039’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in Stuttgart, Germany in 11-cm containers in a glass-covered greenhouse during the spring and under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 15° C. to 35° C., night temperatures ranged from 10° C. to 20° C. and maximum light levels were 70,000 lux. Plants were pinched one time and were about four months old when the photograph and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
