plant named ‘Wesverevostar’

Abstract

A new and distinct cultivar of Verbena plant named ‘Wesverevostar’, characterized by its compact and mounding plant habit; vigorous growth habit; medium-sized leaves; freely flowering habit; red-colored flowers with a light red-colored radiating star pattern; and flowers held above and beyond the foliar plane in rounded umbels.

Description

Botanical designation: Verbena tenera.

Cultivar denomination: ‘WESVEREVOSTAR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena tenera, and hereinafter referred to by the name ‘Wesverevostar’.

The new Verbena plant is a naturally-occurring branch mutation of Verbena tenera ‘Wesverevoo’, disclosed in U.S. Plant Pat. No. 21,620. The new Verbena plant was discovered and selected by the Inventor within a population of plants of ‘Wesverevoo’ in a controlled greenhouse environment in Südlohn, Germany in August, 2008.

Asexual reproduction of the new Verbena plant by terminal cuttings in a controlled greenhouse environment in Südlohn, Germany since October, 2008 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 environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment 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 ‘Wesverevostar’. These characteristics in combination distinguish ‘Wesverevostar’ as a new and distinct Verbena plant:

• • 1. Compact and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Medium-sized leaves.
  • 4. Freely flowering habit.
  • 5. Red-colored flowers with a light red-colored radiating star pattern.
  • 6. Flowers held above and beyond the foliar plane in rounded umbels.

Plants of the new Verbena can be compared to plants of the parent, ‘Wesverevoo’. Plants of the new Verbena differ primarily from plants of ‘Wesverevoo’ in flower color as plants of ‘Wesverevoo’ have solid red-colored flowers.

Plants of the new Verbena can be compared to plants of the Verbena ‘Wesvereme’, disclosed in U.S. Plant Pat. No. 21,637. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Verbena differed primarily from plants of ‘Wesvereme’ in the following characteristics:

• • 1. Plants of the new Verbena were not as compact as plants of ‘Wesvereme’.
  • 2. Plants of the new Verbena had longer internodes than plants of ‘Wesvereme’.
  • 3. Plants of the new Verbena had smaller flowers and inflorescences than plants of ‘Wesvereme’.
  • 4. Plants of the new Verbena and ‘Wesvereme’ differed in flower color as plants of ‘Wesvereme’ had dark red purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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 photographs 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 at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Wesverevostar’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Wesverevostar’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 12-cm and 25-cm containers in a glass-covered greenhouse in Südlohn, Germany and under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 20° C. to 25° C., night temperatures ranged from 16° C. to 18° C. and light levels ranged from 3,000 to 50,000 lux. Plants were 27 weeks old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
