BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Erysimum plant, botanically known as Erysimum hybrida, commonly referred to as Wallflower and hereinafter referred to by the name ‘Doerinbril’.
The new Erysimum plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to develop new Erysimum plants with numerous large and attractive flowers.
The new Erysimum plant originated from a cross-pollination in March, 2018 in Aalsmeer, The Netherlands of a proprietary selection of Erysimum hybrida identified as code number ER17-000004-003, not patented, as the female, or seed, parent, with a proprietary selection of Erysimum hybrida identified as code number ER-0015, not patented, as the male, or pollen, parent. The new Erysimum 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 Aalsmeer, The Netherlands in March, 2019.
Asexual reproduction of the new Erysimum plant by vegetative terminal cuttings in a controlled greenhouse environment in Aalsmeer, The Netherlands since March, 2019 has shown that the unique features of this new Erysimum plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Erysimum 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 ‘Doerinbril’. These characteristics in combination distinguish ‘Doerinbril’ as a new and distinct Erysimum plant:
- 1. Upright and mounding plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit; dense and bushy habit.
- 4. Freely and continuous flowering habit.
- 5. Long flowering period.
- 6. Large deep red to deep purplish red-colored flowers with yellowish orange-colored centers.
- 7. Tolerant to low and high temperatures and good garden performance.
Plants of the new Erysimum differ primarily from plants of the female parent selection in flower color as flowers of plants of the new Erysimum are deep red to deep purplish red in color with yellowish orange-colored centers whereas flowers of plants of the female parent selection are orange in color.
Plants of the new Erysimum differ primarily from plants of the male parent selection in flower color as flowers of plants of the new Erysimum are deep red to deep purplish red in color with yellowish orange-colored centers whereas flowers of plants of the male parent selection are red tinged with purple in color.
Plants of the new Erysimum can be compared to Erysimum hybrida ‘Doeryinyo’, disclosed in U.S. Plant patent application Ser. No. 18/382,507 filed concurrently. Plants of the new Erysimum differ primarily from plants of ‘Doeryinyo’ in flower color as flowers of plants of the new Erysimum are deep red to deep purplish red in color with yellowish orange-colored centers whereas flowers of plants of ‘Doeryinyo’ are dark red to dark purplish red and reddish purple in color. In addition, plants of the new Erysimum are not as vigorous as plants of ‘Doeryinyo’.
Plants of the new Erysimum can also be compared to Erysimum hybrida ‘Poem Pastel’, not patented. In side-by-side comparisons, plants of the new Erysimum differ from plants of ‘Poem Pastel’ in the following characteristics:
- 1. Plants of the new Erysimum have larger leaves than plants of ‘Poem Pastel’.
- 2. Plants of the new Erysimum have larger flowers than plants of ‘Poem Pastel’.
- 3. Flowers of plants of the new Erysimum are deep red to deep purplish red in color with yellowish orange-colored centers whereas flowers of plants of ‘Poem Pastel’ are pastel pink and yellow in color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Erysimum 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 Erysimum plant.
The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘Doerinbril’ grown in a container.
The photograph on the second sheet (FIG. 2) is a close-up view of a typical flower bud and the upper and lower surfaces of typical leaves and flowers.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the early spring in 17-cm containers in a glass-covered greenhouse in Aalsmeer, The Netherlands and under cultural practices typical of commercial Erysimum production. During the production of the plants, average daily temperatures were 21 C and average night temperatures were 15 C. Plants were 28 weeks old when the photographs and description were taken.
