Abstract

A new and distinct cultivar of Verbena plant named ‘RIKAV44501’, characterized by its outwardly spreading to mounding plant habit; vigorous growth habit; freely branching habit; dark green-colored leaves; freely flowering habit; relatively large dark red-colored flowers with light yellow green-colored “eyes” that are held above and beyond the foliar plane; and relative tolerance to Powdery Mildew (Podosphaera xanthii).

Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘RIKAV44501’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘RIKAV44501’.

The new Verbena plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new vigorous and freely-branching Verbena plants with numerous flowers and tolerance to Powdery Mildew (Podosphaera xanthii) and good garden performance.

The new Verbena plant originated from a cross-pollination made by the Inventor on May 18, 2015 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Verbena hybrida identified as code number 14V353-01, not patented, as the female, or seed, parent with a proprietary seedling selection of Verbena hybrida identified as code number 13V349-04, not patented, as the male, or pollen, parent. The new Verbena 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 Bonsall, Calif. on May 26, 2016.

Asexual reproduction of the new Verbena plant by vegetative terminal cuttings in a controlled environment in Bonsall, Calif. since May 30, 2016, 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 ‘RIKAV44501’. These characteristics in combination distinguish ‘RIKAV44501’ as a new and distinct Verbena plant:

    • 1. Outwardly spreading to mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Dark green-colored leaves.
    • 5. Freely flowering habit.
    • 6. Relatively large dark red-colored flowers with light yellow green-colored “eyes” that are held above and beyond the foliar plane.
    • 7. Relatively tolerant to Powdery Mildew (Podosphaera xanthii).

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

    • 1. Plants of the new Verbena are more vigorous than plants of the female parent selection.
    • 2. Plants of the new Verbena have larger flowers than plants of the female parent selection.
    • 3. Plants of the new Verbena are more tolerant to Powdery Mildew than plants of the female parent selection.

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

    • 1. Plants of the new Verbena are more vigorous than plants of the male parent selection.
    • 2. Plants of the new Verbena have larger flowers than plants of the male parent selection.
    • 3. Plants of the new Verbena and the male parent selection differ in flower color as plants of the male parent selection have darker red-colored flowers without white-colored “eyes”.
    • 4. Plants of the new Verbena are more tolerant to Powdery Mildew than plants of the male parent selection.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘Lan Reda07’, disclosed in U.S. Plant Pat. No. 18,986. In side-by-side comparisons, plants of the new Verbena differ primarily from plants of ‘Lan Reda07’ in the following characteristics:

    • 1. Plants of the new Verbena are more vigorous than plants of ‘Lan Reda07’.
    • 2. Plants of the new Verbena have larger flowers than plants of ‘Lan Reda07’.
    • 3. Plants of the new Verbena are more tolerant to Powdery Mildew than plants of ‘Lan Reda07’.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘Usbenal5’, disclosed in U.S. Plant Pat. No. 14,851. In side-by-side comparisons, plants of the new Verbena differ primarily from plants of ‘Usbenal5’ in the following characteristics:

    • 1. Plants of the new Verbena are more mounding than and not as upright as plants of ‘Usbenal5’.
    • 2. Plants of the new Verbena and ‘Usbenal5’ differ in flower color as plants of ‘Usbenal5’ have purple-colored flowers.
    • 3. Plants of the new Verbena are more tolerant to Powdery Mildew than plants of ‘Usbenal5’.
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 actual colors of the new Verbena plant.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘RIKAV44501’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘RIKAV44501’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 10-cm containers in an acrylic-covered greenhouse in Carleton, Mich. and under cultural practices typical of commercial Verbena production. During the production of the plants, day and night temperatures ranged from 18° C. to 24° C. Plants were twelve weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
