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 ‘INJAMSADAW’.

The new Jamesbrittenia plant is a product of a planned breeding program conducted by the Inventor in Heidesheim and Gensingen, 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, attractive flowers and good garden performance.

The new Jamesbrittenia plant originated from a cross-pollination made by the Inventor in August, 2017 in Heidesheim, Germany of Jamesbrittenia hybrida ‘Shakira Yellow’, not patented, as the female, or seed, parent with a proprietary selection of Jamesbrittenia hybrida identified as code number Ja 16 15-6, 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 in July, 2018.

Asexual reproduction of the new Jamesbrittenia plant by vegetative terminal cuttings in a controlled greenhouse environment in Gensingen, Germany since July, 2018 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 ‘INJAMSADAW’. These characteristics in combination distinguish ‘INJAMSADAW’ as a new and distinct Jamesbrittenia plant:

- 1. Compact, upright to outwardly spreading and mounding to trailing and decumbent 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. Single-type flowers that are purple and bright yellow in color.
- 6. Relative resistance to Botrytis.
- 7. Excellent garden performance.

Plants of the new Jamesbrittenia can be compared to plants of the female parent, ‘Shakira Yellow’. In side-by-side comparisons, plants of the new Jamesbrittenia differ primarily from plants of ‘Shakira Yellow’ in flower color as plants of the new Jamesbrittenia have purple and bright yellow-colored flowers whereas plants of ‘Shakira Yellow’ have bright yellow-colored flowers.

Plants of the new Jamesbrittenia can be compared to plants of the male parent selection. In side-by-side comparisons, plants of the new Jamesbrittenia differ primarily from plants of the male parent selection in flower color as plants of the new Jamesbrittenia have purple and bright yellow-colored flowers whereas plants of the male parent selection have red-colored flowers.

Plants of the new Jamesbrittenia can be compared to plants of Jamesbrittenia hybrida ‘INJAMSASKY’, disclosed in a U.S. Plant Patent filed concurrently. In side-by-side comparisons, plants of the new Jamesbrittenia differ primarily from plants of ‘INJAMSASKY’ in flower color as plants of the new Jamesbrittenia have purple and bright yellow-colored flowers whereas plants of ‘INJAMSASKY’ have light reddish purple and white-colored flowers.

Plants of the new Jamesbrittenia can also be compared to plants of Jamesbrittenia hybrida ‘Goldstar’, not patented. In side-by-side comparisons, plants of the new Jamesbrittenia differ primarily from plants of ‘Goldstar’ in the following characteristics:

- 1. Plants of the new Jamesbrittenia are more vigorous than plants of ‘Goldstar’.
- 2. Plants of the new Jamesbrittenia are more freely branching than plants of ‘Goldstar’.
- 3. Plants of the new Jamesbrittenia have a stronger root system than plants of ‘Goldstar’.
- 4. Plants of the new Jamesbrittenia have purple and bright yellow-colored flowers whereas plants of ‘Goldstar’ have yellow-colored flowers.

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 ‘INJAMSADAW’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical flowering plant of ‘INJAMSADAW’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn and winter in 10.8-cm containers in a glass-covered greenhouse in Loudon, New Hampshire and under cultural practices typical of commercial Jamesbrittenia production. During the production of the plants, average daily temperatures were 18° C. Plants were grown under long day/short night conditions and were pinched two weeks after planting. Plants were ten weeks from planting when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used. Measurements were taken on individual plants.
