Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘AKIV572-1’.

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 ‘AKIV572-1’.

The new Verbena plant is a product of a planned breeding program conducted by the Inventor in Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new compact Verbena plants with numerous flowers and resistance to Powdery Mildew.

The new Verbena plant originated from a cross-pollination made by the Inventor on May 20, 2007 in Shiga, Japan of a proprietary seedling selection of Verbena hybrida identified as code number 07V428-01, not patented, as the female, or seed, parent with a proprietary seedling selection of Verbena hybrida identified as ‘Nioimurasaki’, not patented, as the male, or pollen, parent. The new Verbena plant 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 Bonsall, Calif. on Jun. 11, 2008.

Asexual reproduction of the new Verbena plant by terminal cuttings in a controlled environment in Bonsall, Calif. since Jun. 12, 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. 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 ‘AKIV572-1’. These characteristics in combination distinguish ‘AKIV572-1’ as a new and distinct Verbena plant:

    • 1. Compact, semi-upright, mounding to trailing plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Light violet-colored flowers that are held above and beyond the foliar plane.
    • 6. Resistant 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 not as upright as plants of the female parent selection.
    • 2. Plants of the new Verbena have more flexible stems than plants of the female parent selection.
    • 3. Plants of the new Verbena and the female parent selection differ in flower color as plants of the female parent selection have blue-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 upright than plants of the male parent selection.
    • 2. Plants of the new Verbena have larger leaves than plants of the male parent selection.
    • 3. Plants of the new Verbena have larger flowers than plants of the male parent selection.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘USBENAL8’, disclosed in U.S. Plant Pat. No. 14,853. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed primarily from plants of ‘USBENAL8’ in the following characteristics:

    • 1. Plants of the new Verbena were more compact than plants of ‘USBENAL8’.
    • 2. Plants of the new Verbena were more freely branching than plants of ‘USBENAL8’.
    • 3. Plants of the new Verbena had narrower leaves than plants of ‘USBENAL8’.
    • 4. Plants of the new Verbena had smaller flowers than plants of ‘USBENAL8’.
    • 5. Plants of the new Verbena and ‘USBENAL8’ differ in flower color as plants of ‘USBENAL8’ have violet blue-colored flowers.

Plants of the new Verbena can also be compared to plants of the Verbena hybrida ‘Lan Bule’, disclosed in U.S. Plant Pat. No. 15,604. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed primarily from plants of ‘Lan Bule’ in the following characteristics:

    • 1. Plants of the new Verbena had smaller flowers than plants of ‘Lan Bule’.
    • 2. Plants of the new Verbena and ‘Lan Bule’ differed in flower color as plants of ‘Lan Bule’ had dark blue violet-colored flowers.

 DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the spring in 15-cm containers in a polyethylene-covered greenhouse in Bonsall, Calif. During the production of the plants, day temperatures ranged from 18° C. to 32° C., night temperatures ranged from 14° C. to 18° C. and light levels ranged from 7,000 to 10,000 foot-candles. Plants were pinched one time and were nine weeks old when the photographs and description were taken.
