Description

Botanical designation: Verbena X hybrida.

Cultivar Denomination: ‘DOVEREMSUCOBLU’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR AND APPLICANT

The Inventor and Applicant assert that no sales, publications or 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 the Applicant. Inventor and Applicant claim a prior art exemption 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 Verbena plant, botanically known as Verbena X hybrida and hereinafter referred to by the name ‘Doveremsucoblu’.

The new Verbena plant is 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 and early-flowering Verbena plants with numerous large and attractive flowers.

The new Verbena plant originated from a cross-pollination made by the Inventor in July, 2017 in Rheinberg, Germany of a proprietary selection of Verbena X hybrida identified as code number VV16-008762-004, not patented, as the female, or seed, parent with a proprietary selection of Verbena X hybrida identified as code number VV14-004009-001, not patented, as the male, or pollen, parent. The new Verbena 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 Rheinberg, Germany in May, 2019.

Asexual reproduction of the new Verbena plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2019 has shown that the unique features of this new Verbena plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

- 1. Compact, mounding to semi-trailing plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Early and freely flowering habit.
- 5. Large deep purple-colored flowers.
- 6. Good garden performance.

Plants of the new Verbena differ primarily from plants of the female parent selection in flower color as plants of the new Verbena have darker purple-colored flowers than plants of the female parent selection.

Plants of the new Verbena differ primarily from plants of the male parent selection in flower size as plants of the new Verbena have larger flowers than plants of the male parent selection.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘Lan Bule’, disclosed in U.S. Plant Pat. No. 15,604. In side-by-side comparisons, plants of the new Verbena differ primarily from plants of ‘Lan Bule’ in the following characteristics:

- 1. Plants of the new Verbena are more compact than and not as vigorous as plants of ‘Lan Bule’.
- 2. Plants of the new Verbena are more freely branching than plants of ‘Lan Bule’.
- 3. Plants of the new Verbena have larger flowers than plants of ‘Lan Bule’.
- 4. Plants of the new Verbena have darker-colored flowers than plants of ‘Lan Bule’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Verbena 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 Verbena plant.

The photograph is a side perspective view of a typical flower plant of ‘Doveremsucoblu’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in 22-cm containers during the spring and early summer in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Verbena 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 three weeks after planting and were twelve weeks old when the photograph and description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, 2007, except where general terms of ordinary dictionary significance are used.
