USPP17921P2 - Verbena plant named ‘Sumverb 13’ - Google Patents

Abstract

A new and distinct cultivar of Verbena plant named ‘Sumverb 13’, characterized by its outwardly spreading and cascading plant habit; vigorous growth habit; early and freely flowering habit; and large red purple-colored flowers.

Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘Sumverb 13’.

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 ‘Sumverb 13’.

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

The new Verbena originated from a cross-pollination made by the Inventor in March, 2002 of a proprietary seedling selection of Verbena hybrida identified as Seedling 12, not patented, as the female, or seed, parent with a proprietary seedling selection of Verbena hybrida identified as Seedling 1, not patented, as the male, or pollen, parent. The cultivar Sumverb 13 was discovered and selected by the Inventor as a flowering plant within the progeny from the aforementioned cross-pollination in a controlled environment in Lüdinghausen, Germany in September, 2002.

Asexual reproduction of the new cultivar by cuttings at Lüdinghausen, Germany, since October, 2002, 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 ‘Sumverb 13’. These characteristics in combination distinguish ‘Sumverb 13’ as a new and distinct cultivar:

• • 1. Outwardly spreading and cascading plant habit.
  • 2. Vigorous growth habit.
  • 3. Early and freely flowering habit.
  • 4. Large red purple-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 flower earlier 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 more compact than plants of the male parent selection.
  • 2. Plants of the new Verbena are more cascading than plants of the male parent selection.

The new Verbena can be compared to the cultivar, Sunvivaro, disclosed in U.S. Plant Pat. No. 13,724. However, in side-by-side comparisons conducted in Lüdinghausen, Germany, plants of the new Verbena differed from plants of the cultivar Sunvivaro in the following characteristics:

• • 1. Plants of the new Verbena were larger than plants of the cultivar Sunvivaro.
  • 2. Plants of the new Verbena were more cascading than and not as upright as plants of the cultivar Sunvivaro.
  • 3. Plants of the new Verbena were more freely branching than plants of the cultivar Sunvivaro.
  • 4. Plants of the new Verbena flowered earlier than plants of the cultivar Sunvivaro.
  • 5. Plants of the new Verbena were more freely flowering than plants of the cultivar Sunvivaro.
  • 6. Plants of the new Verbena had larger inflorescences and larger flowers than plants of the cultivar Sunvivaro.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants grown in 37-cm containers were used for the aforementioned photographs and following description. Plants had been growing for about four months when the photographs and the description were taken. Plants were grown under conditions which closely approximate commercial production conditions during the spring and summer in Lüdinghausen, Germany in an outdoor nursery. During the production period, day temperatures ranged from about 16° C. to about 30° C. and night temperatures ranged from about 8° C. to about 14° C.
