Lantana plant named ‘Weslamo’

Abstract

A new and distinct cultivar of Lantana plant named ‘Weslamo’, characterized by its compact, upright and mounding plant habit; vigorous growth habit; durable, dark green-colored leaves; freely flowering habit; and flowers that are held above the foliage in compact inflorescences and are initially yellow becoming orange and eventually dark pink in color.

Description

Botanical designation: Lantana camara.

Cultivar denomination: ‘Weslamo’.

BACKGROUND OF THE INVENTION

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

The new Lantana is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The objective of the breeding program is to create new freely branching Lantana cultivars with attractive flower coloration.

The new Lantana originated from a cross-pollination made by the Inventor in 2000 in Südlohn, Germany of a proprietary selection of Lantana camara identified as code number 00PL3, not patented, as the female, or seed, parent with a proprietary selection of Lantana camara identified as code number 00PL6, not patented, as the male, or pollen, parent. The new Lantana was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Südlohn, Germany in 2001.

Asexual reproduction of the new Lantana by vegetative cuttings in a controlled environment in Südlohn, Germany since 2001, has shown that the unique features of this new Lantana are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Weslamo has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Weslamo’. These characteristics in combination distinguish ‘Weslamo’ as a new and distinct cultivar of Lantana:

• • 1. Compact, upright and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Durable dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Flowers that are held above the foliage in compact inflorescences and are initially yellow becoming orange and eventually dark pink in color.

Plants of the new Lantana can be compared to plants of the female parent selection. Plants of the new Lantana differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Lantana are more compact than plants of the female parent selection.
  • 2. Plants of the new Lantana are more freely branching than plants of the female parent selection.
  • 3. Plants of the new Lantana have smaller leaves than plants of the female parent selection.
  • 4. Plants of the new Lantana have more compact inflorescences with larger flowers than plants of the female parent selection.
  • 5. Flowers of plants of the new Lantana are yellow becoming orange and eventually dark pink in color whereas flowers of plants of the female parent selection are yellow becoming orange in color with development.

Plants of the new Lantana can be compared to plants of the male parent selection. Plants of the new Lantana differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Lantana have more compact inflorescences than plants of the male parent selection.
  • 2. Flowers of plants of the new Lantana are yellow becoming orange and eventually dark pink in color whereas flowers of plants of the male parent selection are orange becoming red in color with development.

Plants of the new Lantana can be compared to plants of the Lantana cultivar Dallas Red, not patented. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Lantana differed from plants of the cultivar Dallas Red in the following characteristics:

• • 1. Plants of the new Lantana were larger and more vigorous than plants of the cultivar Dallas Red.
  • 2. Plants of the new Lantana were more freely branching than plants of the cultivar Dallas Red.
  • 3. Plants of the new Lantana had larger leaves than plants of the cultivar Dallas Red.
  • 4. Plants of the new Lantana had larger inflorescences than plants of the cultivar Dallas Red.
  • 5. Plants of the new Lantana and the cultivar Dallas Red differed in flower color as plants of the cultivar Dallas Red initially had yellow-colored flowers that became deep red with development.

Plants of the new Lantana can also be compared to plants of the Lantana cultivar Balucgold, disclosed in U.S. Plant Pat. No. 14,634. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Lantana differed from plants of the cultivar Balucgold in the following characteristics:

• • 1. Plants of the new Lantana had larger leaves than plants of the cultivar Balucgold.
  • 2. Plants of the new Lantana had larger inflorescences and flowers than plants of the cultivar Balucgold.
  • 3. Plants of the new Lantana and the cultivar Balucgold differed in flower color as plants of the cultivar Balucgold had yellow-colored flowers.
