USPP17926P2 - Verbena plant named ‘Duefarwi’ - Google Patents

Abstract

A new and distinct cultivar of Verbena plant named ‘Duefarwi’, characterized by its compact, outwardly spreading and cascading plant habit; freely branching habit; freely flowering habit; and white-colored flowers.

Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘Duefarwi’.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is co-pending with the following related applications: Title: Verbena Plant Named ‘Duefarsopi’. Applicant: Marga Dümmen. Title: Verbena Plant Named ‘Duefarvi’. Applicant: Marga Dümmen.

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 ‘Duefarwi’.

The new Verbena is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to develop new trailing Verbena cultivars with large and intensely-colored flowers.

The new Verbena originated from a cross-pollination made by the Inventor in July, 2001 of a proprietary seedling selection of Verbena hybrida identified as F-11-23, not patented, as the female, or seed, parent with a proprietary seedling selection of Verbena hybrida identified as F-20-12, not patented, as the male, or pollen, parent. The cultivar Duefarwi was discovered and selected by the Inventor as a flowering plant within the progeny from the aforementioned cross-pollination in a controlled environment in Rheinberg, Germany in July, 2002.

Asexual reproduction of the new cultivar by cuttings at Rheinberg, Germany, since July, 2004, 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 ‘Duefarwi’. These characteristics in combination distinguish ‘Duefarwi’ as a new and distinct cultivar:

• • 1. Compact, outwardly spreading and cascading plant habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. White-colored flowers.

Plants of the new Verbena differ 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. Plants of the new Verbena have larger flowers than plants of the female parent selection.

Plants of the new Verbena differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Verbena are not as compact as plants of the male parent selection.
  • 2. Plants of the new Verbena differ from plants of the male parent selection in flower color as plants of the male parent selection have lilac-colored flowers.

Plants of the new Verbena differ primarily from plants of the cultivar Duefarsopi, disclosed in a U.S. Plant patent application Ser. No. 11/349,721, and the cultivar Duefarvio, disclosed in a U.S. Plant patent application Ser. No. 11/349,722, in flower color.

The new Verbena can be compared to the cultivar, Sunmaririho, not patented. However, in side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Verbena differed from plants of the cultivar Sunmaririho in the following characteristics:

• • 1. Plants of the new Verbena were more compact than plants of the cultivar Sunmaririho.
  • 2. Plants of the new Verbena had longer leaves with longer petioles than plants of the cultivar Sunmaririho.
  • 3. Plants of the new Verbena had larger umbels and larger flowers than plants of the cultivar Sunmaririho.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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 slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Verbena. The photograph is a close-up view of typical leaves, flower buds and flowers of ‘Duefarwi’.

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. The aforementioned photograph, following observations and measurements describe plants grown during the spring in Rheinberg, Germany, in a glass-covered greenhouse and under conditions which approximate those generally used in commercial Verbena production. Single plants were grown in 13-cm containers and pinched about one week after planting. During the production of the plants, day and night temperatures were about 18° C. and light levels were about 4,500 foot-candles. Plants used in the photograph and for the botanical description were about four months old.
