Botanical designation: Jamesbrittenia hybrida.
Cultivar denomination: ‘INJAMLAVFL’.
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 ‘INJAMLAVFL’.
The new Jamesbrittenia plant is a product of a planned breeding program conducted by the Inventor in 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, large attractive flowers and good garden performance.
The new Jamesbrittenia plant originated from a cross-pollination made by the Inventor on Jul. 16, 2021 in Gensingen, Germany of a proprietary selection of Jamesbrittenia hybrida identified as code number Ja 20 3-1, not patented, as the female, or seed, parent with a proprietary selection of Jamesbrittenia hybrida identified as code number Ja 20 25-11, 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 Gensingen, Germany on Apr. 3, 2022.
Asexual reproduction of the new Jamesbrittenia plant by vegetative terminal cuttings in a controlled greenhouse environment in Gensingen, Germany since Apr. 3, 2022 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 ‘INJAMLAVFL’. These characteristics in combination distinguish ‘INJAMLAVFL’ 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 bright red in color with bright yellow green-colored centers.
- 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 more freely branching than 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 bright red in color with bright yellow green-colored centers whereas flowers of plants of the female parent selection are salmon pink in color.
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 the following characteristics:
- 1. Plants of the new Jamesbrittenia are more vigorous and stronger than plants of the male parent selection.
- 2. Plants of the new Jamesbrittenia have larger flowers than plants of the male parent selection.
Plants of the new Jamesbrittenia can also be compared to plants of Jamesbrittenia hybrida ‘Sunbrittenia Scarlet’, not patented. In side-by-side comparisons, plants of the new Jamesbrittenia differ primarily from plants of ‘Sunbrittenia Scarlet’ in the following characteristics:
- 1. Plants of the new Jamesbrittenia are not as vigorous as plants of ‘Sunbrittenia Scarlet’.
- 2. Plants of the new Jamesbrittenia are more freely branching than plants of ‘Sunbrittenia Scarlet’.
- 3. Plants of the new Jamesbrittenia flower earlier than plants of ‘Sunbrittenia Scarlet’.
- 4. Plants of the new Jamesbrittenia have shorter peduncles than plants of ‘Sunbrittenia Scarlet’.

DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the late summer to early autumn in 813 ml 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, day temperatures ranged from 18° C. to 20° C. and night temperatures ranged from 16° C. to 18° C. Plants were pinched one time and were eight weeks from planting rooted young plants 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.
