Abstract

A new and distinct cultivar of Verbena plant named ‘RIKAV38602’, characterized by its compact, mounding and upright to eventually trailing plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; freely flowering habit; relatively large burgundy-colored flowers that are held above and beyond the foliar plane; and relative tolerance to Powdery Mildew (Podosphaera xanthii).

Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘RIKAV38602’.

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 ‘RIKAV38602’.

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).

The new Verbena plant originated from a cross-pollination made by the Inventor on May 20, 2013 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Verbena hybrida identified as code number 12V258-05, not patented, as the female, or seed, parent with a proprietary seedling selection of Verbena hybrida identified as code number 08V665-02, 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. 11, 2014.

Asexual reproduction of the new Verbena plant by vegetative terminal cuttings in a controlled environment in Bonsall, Calif. since Jun. 12, 2014, 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 ‘RIKAV38602’. These characteristics in combination distinguish ‘RIKAV38602’ as a new and distinct Verbena plant:

- 1. Compact, mounding and upright to eventually trailing plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Dark green-colored leaves.
- 5. Freely flowering habit.
- 6. Relatively large dark burgundy-colored flowers 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 ‘Lan Peachy’ in the following characteristics:

- 1. Plants of the new Verbena have larger flowers than plants of the female parent selection.
- 2. Plants of the new Verbena and the female parent selection differ in flower color as plants of the female parent selection have lighter burgundy-colored flowers.

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 compact than 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 ‘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 compact than plants of ‘Usbenal5’.
- 2. Plants of the new Verbena have narrower leaves than plants of ‘Usbenal5’.
- 3. Plants of the new Verbena and ‘Usbenal5’ differ in flower color as flowers of ‘Usbenal5’ are purple in color.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘KLEVP08383’, disclosed in U.S. Plant Pat. No. 21,056. In side-by-side comparisons, plants of the new Verbena differ primarily from plants of ‘KLEVP08383’ in the following characteristics:

- 1. Plants of the new Verbena are more freely branching than plants of ‘KLEVP08383’.
- 2. Plants of the new Verbena are more freely flowering than plants of ‘KLEVP08383’.

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 30° C. and light levels averaged 1,500 foot-candles. Plants were seven 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.
