Abstract

A new and distinct cultivar of Lantana plant named ‘Dolanhavharmo’, characterized by its compact, upright and mounding plant habit; moderately vigorous growth habit and moderate growth rate; freely branching growth habit; dense and bushy plant form; dark green-colored leaves; early and freely flowering habit; long flowering period; flowers that are initially orange in color becoming bright red with development; and good garden performance.

Description

Botanical designation: Lantana camara.

Cultivar denomination: ‘DOLANHAVHARMO’.

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 ‘Dolanhavharmo’.

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 2020 in Rheinberg, Germany of a proprietary selection of Lantana camara identified as code number LA-0133, not patented, as the female, or seed, parent with a proprietary selection of Lantana camara identified as code number LA19-K0019, 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 April 2021.

Asexual reproduction of the new Lantana plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since April 2021 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 ‘Dolanhavharmo’. These characteristics in combination distinguish ‘Dolanhavharmo’ 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 initially orange in color becoming bright red with development.
- 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 initially orange in color becoming bright red with development whereas flowers of plants of the female parent selection are mostly orange in color. In addition, plants of the new Lantana are more freely branching 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 plant habit as plants of the new Lantana are more compact than plants of the male parent selection. In addition, leaves of plants of the new Lantana are darker green in color than leaves of plants of the male parent selection.

Plants of the new Lantana can be compared to plants of the Lantana camara ‘Bant Reda09’, disclosed in U.S. Plant Pat. No. 20,531. In side-by-side comparisons, plants of the new Lantana differ from plants of ‘Bant Reda09’ in the following characteristics:

- 1. Plants of the new Lantana are more compact and more upright than plants of ‘Bant Reda09’.
- 2. Plants of the new Lantana are more freely branching and denser than plants of ‘Bant Reda09’.
- 3. Plants of the new Lantana have longer and darker green- colored leaves than plants of ‘Bant Reda09’.
- 4. Plants of the new Lantana have shorter and broader inflorescences than plants of ‘Bant Reda09’.

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 ‘Dolanhavharmo’ 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 twelve weeks old when the photograph and the detailed description were 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.
