USPP20988P2 - Verbena plant named ‘Duemplav’ - Google Patents

Abstract

A new and distinct cultivar of Verbena plant named ‘Duemplav’, characterized by its mounding and cascading plant habit; freely branching habit; freely flowering habit; and large lavender-colored flowers that are held above and beyond the foliage in mounded umbels.

Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘DUEMPLAV’.

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 ‘Duemplav’.

The new Verbena plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new uniform Verbena plants with large and attractive flowers.

The new Verbena plant originated from a self-pollination made by the Inventor in August, 2006 in Rheinberg, Germany of a proprietary selection of Verbena hybrida identified as code number V05-3508-1, not patented. The new Verbena plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated self-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2007.

Asexual reproduction of the new Verbena plant by terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since May, 2007 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, daylength 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 ‘Duemplav’. These characteristics in combination distinguish ‘Duemplav’ as a new and distinct cultivar of Verbena:

• • 1. Mounding and cascading plant habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Large lavender-colored flowers that are held above and beyond the foliage in mounded umbels.

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

• • 1 . Plants of the new Verbena are not as upright as plants of the parent selection.
  • 2. Plants of the new Verbena and the parent selection differ in flower color.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘Duplena’, disclosed in U.S. Plant Pat. No. 15,687. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Verbena differed from plants of ‘Duplena’ in the following characteristics:

• • 1. Plants of the new Verbena had smaller leaves than plants of ‘Duplena’.
  • 2. Plants of the new Verbena had larger flowers and larger umbels than plants of ‘Duplena’.
  • 3. Flowers of plants of the new Verbena were lighter in color than flowers of plants of ‘Duplena’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Verbena plant, 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 comprises a close-up view of typical leaves and flowers of ‘Duemplav’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in 13-cm containers in Rheinberg, Germany in a glass-covered greenhouse during the summer and under conditions which closely approximate commercial production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time about one week after planting. Plants had been growing for four months when the photograph and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
