Abstract: A new and distinct cultivar of Verbena plant named `USBENAL25`, characterized by its semi-upright and outwardly spreading plant habit; vigorous growth habit; large dark violet-colored flowers; and resistance to Powdery Mildew.
Claim: It is claimed:

1. A new and distinct cultivar of Verbena plant named `USBENAL25`, as illustrated and described.
Description: Botanicalclassification/cultivar designation: Verbena hybrida cultivar USBENAL25.

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 `USBENAL25`.

The new Verbena is a product of a planned breeding program conducted by the Inventor in Hikone, Shiga, Japan. The objective of the breeding program is to develop new disease-resistant and high temperature-tolerant Verbena cultivars withsemi-upright plant habit and attractive flower coloration.

The new Verbena originated from a cross-pollination made by the Inventor on Apr. 20, 1999 of an unknown selection of Verbena hybrida, not patented, as the female, or seed, parent with an unnamed proprietary selection of Verbena hybrida, notpatented, as the male, or pollen, parent. The cultivar USBENAL25 was discovered and selected by the Inventor as a flowering plant within the progeny from this cross-pollination in a controlled environment in Bonsall, Calif. on Jun. 10, 2000.

Asexual reproduction of the new cultivar by cuttings taken at Bonsall, Calif., since Jun. 20, 2000, has shown that the unique features of this new Verbena are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of `USBENAL25`. These characteristics in combination distinguish `USBENAL25` as a new and distinct cultivar: 1. Semi-upright and outwardlyspreading plant habit. 2. Vigorous growth habit. 3. Large dark violet-colored flowers. 4. Resistant to Powdery Mildew.

In side-by-side comparisons conducted in Hikone, Shiga, Japan, plants of the new Verbena differed from plants of the female parent selection in the following characteristics: 1. Plants of the new Verbena were not as upright as plants of thefemale parent selection. 2. Plants of the new Verbena were more vigorous than plants of the female parent selection. 3. Plants of the new Verbena were resistant to Powdery Mildew whereas plants of the female parent selection were susceptible toPowdery Mildew.

In side-by-side comparisons conducted in Hikone, Shiga, Japan, plants of the new Verbena differed from plants of the male parent selection primarily in flowering time as plants of the new Verbena flowered earlier than plants of the male parentselection.

The new Verbena can be compared to the cultivar, Temari Coral Blue, not patented. However, in side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed from plants of the cultivar Temari Coral Blue in thefollowing characteristics: 1. Plants of the new Verbena were more upright than plants of the cultivar Temari Coral Blue. 2. Plants of the new Verbena flowered earlier than plants of the cultivar Temari Coral Blue. 3. Plants of the new Verbena hadlarger flowers than plants of the cultivar Temari Coral Blue.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Verbena.

The photograph at the top of the sheet comprises a side perspective view of three typical plants of `USBENAL25` grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers and leaves of `USBENAL25`.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants grown in 15-cm containers with three plantsper container were used for the aforementioned photographs and following description. Plants were about four weeks from planting rooted cuttings. Plants were grown under conditions which closely approximate commercial production conditions during thespring in Bonsall, Calif. in an outdoor nursery. During the production period, day temperatures ranged from about 18 to about 35.degree. C. and night temperatures ranged from about 7 to about 18.degree. C. Botanical classification: Verbena hybridacultivar USBENAL25. Parentage: Female parent.--Unknown selection of Verbena hybrida, not patented. Male parent.--Unnamed proprietary selection of Verbena hybrida, not patented. Propagation: Type cutting.--Vegetative tip cuttings. Time to initiateroots.--About 7 days at 18.degree. C. Time to develop roots.--About 21 days at 18.degree. C. Root description.--Fibrous; whitish in color. Rooting habit.--Freely branching. Plant description: General appearance.--Semi-upright and outwardly spreadingplant habit; eventually somewhat trailing plant habit. Growth and branching habit.--Freely basal branching; about three lateral branches develop per plant. Pinching, that is, removal of the terminal apices, enhances branching with lateral branchespotentially forming at every node. Vigorous growth habit; moderate growth rate. Plant height.--About 16 cm.
