Abstract

A new and distinct Jamesbrittenia plant named ‘ja19 50-008’, characterized by its upright to outwardly spreading and mounding plant habit; vigorous growth habit and rapid growth rate; freely branching habit; dense and bushy plant form; early and freely flowering habit; relatively large single-type flowers that are purple in color with white and yellow-colored centers and darker purple-colored stripes; and excellent garden performance.

Description

Botanical designation: Jamesbrittenia hybrida.
Cultivar denomination: ‘ja19 50-008’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Jamesbrittenia plant, botanically known as Jamesbrittenia hybrida, commonly referred to as South African Phlox and hereinafter referred to by the name ‘ja19 50-008’.
The new Jamesbrittenia plant is a product of a planned breeding program conducted by the Inventor in Heidesheim, Germany. The objective of the breeding program is to create new compact, freely-branching and uniformly mounding Jamesbrittenia plants with early and freely flowering habit, large attractive flowers and good garden performance.
The new Jamesbrittenia plant originated from a cross-pollination made by the Inventor during the summer of 2018 in Heidesheim, Germany of the proprietary selection of Jamesbrittenia hybrida identified as code number ja18 4-7, not patented, as the female, or seed, parent with Jamesbrittenia hybrida ‘Summer Dream Violet Eye’, not patented, as the male, or pollen, parent. The new Jamesbrittenia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heidesheim, Germany during the summer of 2019.
Asexual reproduction of the new Jamesbrittenia plant by vegetative terminal cuttings in a controlled greenhouse environment in Heidesheim, Germany since the summer of 2019 has shown that the unique features of this new Jamesbrittenia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Jamesbrittenia 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 ‘ja19 50-008’. These characteristics in combination distinguish ‘ja19 50-008’ as a new and distinct Jamesbrittenia plant:
    • 1. Upright to outwardly spreading and mounding plant habit.
    • 2. Vigorous growth habit and rapid growth rate.
    • 3. Freely branching habit; dense and bushy plant form.
    • 4. Early and freely flowering habit.
    • 5. Relatively large single-type flowers that are purple in color with white and yellow-colored centers and darker purple-colored stripes.
    • 6. Excellent garden performance.
Plants of the new Jamesbrittenia can be compared to plants of the female parent selection. In side-by-side comparisons, plants of the new Jamesbrittenia differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Jamesbrittenia are not as upright as plants of the female parent selection.
    • 2. Plants of the new Jamesbrittenia have larger flowers than plants of the female parent selection.
    • 3. Flowers of plants of the new Jamesbrittenia are purple in color with white and yellow-colored centers and darker purple-colored stripes whereas flowers of plants of the female parent selection are light pink in color.
Plants of the new Jamesbrittenia can be compared to plants of the male parent, ‘Summer Dream Violet Eye’. In side-by-side comparisons, plants of the new Jamesbrittenia differ primarily from plants of ‘Summer Dream Violet Eye’ in the following characteristics:
    • 1. Plants of the new Jamesbrittenia are stronger than plants of ‘Summer Dream Violet Eye’.
    • 2. Plants of the new Jamesbrittenia have larger flowers than plants of ‘Summer Dream Violet Eye’.
    • 3. Flowers of plants of the new Jamesbrittenia are purple in color with white and yellow-colored centers and darker purple-colored stripes whereas flowers of plants of ‘Summer Dream Violet Eye’ are dark bluish violet in color.
Plants of the new Jamesbrittenia can also be compared to plants of Jamesbrittenia hybrida ‘INJAIVISASKY’, disclosed in U.S. Plant Pat. No. 34,114. In side-by-side comparisons, plants of the new Jamesbrittenia differ primarily from plants of ‘INJAIVISASKY’ in flower color as plants of the new Jamesbrittenia have purple-colored flowers with white and yellow-colored centers and darker purple-colored stripes whereas plants of ‘INJAIVISASKY’ have light reddish purple-colored flowers with white-colored centers. In addition, plants of the new Jamesbrittenia are more vigorous than and not as compact as plants of ‘INJAIVISASKY’.
Plants of the new Jamesbrittenia can also be compared to plants of Jamesbrittenia hybrida ‘INJAMSADAW’, disclosed in U.S. Plant Pat. No. 34,115. In side-by-side comparisons, plants of the new Jamesbrittenia differ primarily from plants of ‘INJAMSADAW’ in flower color as plants of the new Jamesbrittenia have purple-colored flowers with white and yellow-colored centers and darker purple-colored stripes whereas plants of ‘INJAMSADAW’ have purple-colored flowers with bright yellow-colored centers. In addition, plants of the new Jamesbrittenia are more vigorous than and not as compact as plants of ‘INJAMSADAW’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Jamesbrittenia plant 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 Jamesbrittenia plant.
The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘ja19 50-008’ grown in a container.
The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical flowering plant of ‘ja19 50-008’.
