Inventor: Arjan Koot

Filed: Nov. 30, 2022; concurrently with the instant application.

An 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 Aug. 5, 2022, application number 2022/1854. Foreign priority is not claimed to this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lantana plant, botanically known as Lantana camara and hereinafter referred to by the name ‘Dolanhagol 23’.

The new Lantana 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, freely-branching Lantana plants with early and freely flowering habit and large attractive flowers.

The new Lantana plant originated from a cross-pollination in July, 2019 in Rheinberg, Germany of a proprietary selection of Lantana camara identified as code number LA-0124, not patented, as the female, or seed, parent with a proprietary selection of Lantana camara identified as code number LA17-000101-001, not patented, as the male, or pollen, parent. The new Lantana 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, 2022.

Asexual reproduction of the new Lantana plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2022 has shown that the unique features of this new Lantana plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Lantana 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 ‘Dolanhagol 23’. These characteristics in combination distinguish ‘Dolanhagol 23’ as a new and distinct Lantana plant:

• • 1. Compact, upright and mounding plant habit.
  • 2. Moderately vigorous growth habit and moderate growth rate.
  • 3. Freely branching growth habit; dense and bushy plant form.
  • 4. Dark green-colored leaves.
  • 5. Early and freely flowering habit.
  • 6. Long flowering period.
  • 7. Flowers that are dark yellow in color.
  • 8. Good garden performance.

Plants of the new Lantana can be compared to plants of the female parent selection. Plants of the new Lantana differ primarily from plants of the female parent selection in flower color as flowers of plants of the new Lantana are dark yellow in color whereas flowers of plants of the female parent selection are red and yellow in color. In addition, plants of the new Lantana have broader leaves than plants of the female parent selection.

Plants of the new Lantana can be compared to plants of the male parent selection. Plants of the new Lantana differ primarily from plants of the male parent selection in flower color as flowers of plants of the new Lantana are dark yellow in color whereas flowers of plants of the male parent selection are pink in color. In addition, plants of the new Lantana are not as compact as plants of the male parent selection.

Plants of the new Lantana can be compared to plants of the Lantana camara ‘Dolanhearora’, disclosed in a U.S. Plant patent application Ser. No. 18/072,108 filed concurrently. In side-by-side comparisons, plants of the new Lantana differ from plants of ‘Dolanhearora’ in the following characteristics:

• • 1. Plants of the new Lantana are more compact than and not as vigorous as plants of ‘Dolanhearora’.
  • 2. Plants of the new Lantana have smaller inflorescences with smaller flowers than plants of ‘Dolanhearora’.
  • 3. Plants of the new Lantana and ‘Dolanhearora’ differ in flower color as flowers of plants of the new Lantana are dark yellow in color whereas flowers of plants of ‘Dolanhearora’ are initially orange in color becoming dark reddish orange with development.

Plants of the new Lantana can also be compared to plants of the Lantana camara ‘Bamboo’, not patented. In side-by-side comparisons, plants of the new Lantana differ from plants of ‘Bamboo’ in the following characteristics:

• • 1. Plants of the new Lantana are more compact than and not as vigorous as plants of ‘Bamboo’.
  • 2. Plants of the new Lantana are more upright than and not as trailing as plants of ‘Bamboo’.
  • 3. Plants of the new Lantana have longer and broader leaves than plants of ‘Bamboo’.
  • 4. Plants of the new Lantana and ‘Bamboo’ differ in flower color as flowers of plants of the new Lantana are darker yellow in color than flowers of plants of ‘Bamboo’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Lantana 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 Lantana plant. The photograph is a side perspective view of a typical flowering plant of ‘Dolanhagol 23’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the spring and summer in 22-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under commercial practices typical of commercial Lantana production. During the production of the plants, day and night temperatures averaged 18° C. and light levels ranged from 1,500 to 4,500 lux. Plants were pinched three weeks after planting and were twelve weeks old when the photograph was taken and 25 weeks old when the description was taken.
