STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

A European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Dümmen Group B.V. of De Lier, The Netherlands on Jul. 25, 2023, application number 2023/1569. Foreign priority is not claimed to this application.

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

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 ‘Doerywala’.

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 ER16-000007-002, not patented, as the female, or seed, parent, with a proprietary selection of Erysimum hybrida identified as code number ER16-000009-002, 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 ‘Doerywala’. These characteristics in combination distinguish ‘Doerywala’ as a new and distinct Erysimum plant:

• • 1. Upright and mounding plant habit.
  • 2. Freely branching habit; dense and bushy habit.
  • 3. Freely and continuous flowering habit.
  • 4. Long flowering period.
  • 5. Large light purple-colored flowers.
  • 6. Tolerant to low and high temperatures.

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 lighter purple in color than flowers of plants of the female parent selection.

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 light purple in color whereas flowers of plants of the male parent selection are red in color.

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 are more compact 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 light purple in color 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 ‘Doerywala’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical flower bud, the upper surface of a typical flower and the upper and lower surfaces of typical leaves.

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 25 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Second Edition, except where general terms of ordinary dictionary significance are used.
