Description

Botanical designation: Scaevola aemula.

Cultivar denomination: ‘DOSCASCAPUBI’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE

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 Scaevola plant, botanically known as Scaevola aemula and hereinafter referred to by the name ‘Doscascapubi’.

The new Scaevola plant a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact, mounding and early-flowering Scaevola plants with numerous attractive flowers.

The new Scaevola plant originated from a cross-pollination in Rheinberg, Germany in July, 2019 of a proprietary selection of Scaevola aemula identified by the code number CC17-000507-001, not patented, as the female, or seed, parent with a proprietary selection of Scaevola aemula identified as code number CC17-001911-001, not patented, as the male, or pollen, parents. The new Scaevola plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2020.

Asexual reproduction of the new Scaevola plant by vegetative tip cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2020 has shown that the unique features of this new Scaevola plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Scaevola 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 ‘Doscascapubi’. These characteristics in combination distinguish ‘Doscascapubi’ as a new and distinct Scaevola plant:

- 1. Mounding to outwardly spreading plant habit.
- 2. Freely branching habit.
- 3. Early and freely flowering habit.
- 4. Long flowering period.
- 5. Flowers that are purple in color.
- 6. Good container and garden performance.

Plants of the new Scaevola can be compared to plants of the female and male parent selections. Plants of the new Scaevola differ primarily from plants of the parent selections in flower color as plants of the new Scaevola have purple-colored flowers whereas plants of the parent selections are pink in color.

Plants of the new Scaevola can be compared to plants of the Scaevola aemula ‘Purple Haze’, not patented. In side-by-side comparisons, plants of the new Scaevola differ from plants of the ‘Purple Haze’ in the following characteristics:

- 1. Plants of the new Scaevola are shorter and broader than plants of ‘Purple Haze’.
- 2. Plants of the new Scaevola have broader leaves than plants of ‘Purple Haze’.
- 3. Plants of the new Scaevola are more freely flowering than plants of ‘Purple Haze’.
- 4. Plants of the new Scaevola have larger flowers than plants of ‘Purple Haze’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Scaevola plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Scaevola plant. The photograph is a close-up view of a typical flowering plant of ‘Doscascapubi’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the spring and early summer in 22-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Scaevola production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time about three weeks after planting. Plants were twelve weeks old when the photograph was taken and 25 weeks old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
