Abstract

A new and distinct cultivar of Verbena plant named ‘RIKAV17805’, characterized by its compact, outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; dark green-colored leaves; freely flowering habit; white-colored flowers that are held above and beyond the foliar plane; and relative tolerance to powdery mildew.

Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘RIKAV17805’.

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 ‘RIKAV17805’.

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.

The new Verbena plant originated from a cross-pollination made by the Inventor on May 5, 2010 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Verbena hybrida identified as code number 08V603-01, not patented, as the female, or seed, parent with a proprietary seedling selection of Verbena hybrida identified as code number 09V852-01, 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 Jun. 9, 2011.

Asexual reproduction of the new Verbena plant by terminal cuttings in a controlled environment in Bonsall, Calif. since Jun. 10, 2011 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 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 ‘RIKAV17805’. These characteristics in combination distinguish ‘RIKAV17805’ as a new and distinct Verbena plant:

- 1. Compact, outwardly spreading and mounding plant habit.
- 2. Vigorous growth habit.
- 3. Freely branching habit.
- 4. Dark green-colored leaves.
- 5. Freely flowering habit.
- 6. White-colored flowers that are held above and beyond the foliar plane.
- 7. Relatively tolerant to powdery mildew.

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 freely branching than plants of the female parent selection.
- 2. Leaves of plants of the new Verbena are darker green in color than leaves of 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 mounding than and not as upright as plants of the male parent selection.
- 2. Plants of the new Verbena are more freely flowering than plants of the male parent selection.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘AKIV344-01’, disclosed in U.S. Plant Pat. No. 21,643. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed primarily from plants of ‘AKIV344-01’ in the following characteristics:

- 1. Plants of the new Verbena were more compact and mounding than and not as trailing as plants of ‘AKIV344-01’.
- 2. Leaves of plants of the new Verbena were darker green in color than leaves of plants of ‘AKIV344-01’.
- 3. Plants of the new Verbena and ‘AKIV344-01’ differ in flower color as plants of ‘AKIV344-01’ have pink-colored flowers.

Plants of the new Verbena can also be compared to plants of the Verbena hybrida ‘Vepita White’, not patented. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed primarily from plants of ‘Vepita White’ in the following characteristics:

- 1. Plants of the new Verbena were larger than plants of ‘Vepita White’.
- 2. Plants of the new Verbena had larger flowers than plants of ‘Vepita White’.
- 3. Plants of the new Verbena were more tolerant to powdery mildew than plants of ‘Vepita White’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late autumn in 11.4-cm containers in a polyethylene-covered greenhouse in Bonsall, Calif. During the production of the plants, day temperatures ranged from 21° C. to 38° C., night temperatures averaged 21° C. and light levels ranged from 7,000 to 10,000 foot-candles. Plants were pinched one time at planting and were two months 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.
