Verbena plant named ‘USBENA6201’

Abstract

A new and distinct cultivar of Verbena plant named ‘USBENA6201’, characterized by its outwardly to low spreading and relatively compact plant habit; vigorous growth habit; freely branching habit; freely flowering habit; red purple-colored flowers that are held above and beyond the foliage; and tolerance to Powdery Mildew.

Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘USBENA6201’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Verbena, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘USBENA6201’.

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 create new disease-resistant and high temperature-tolerant Verbena cultivars with semi-upright plant habit and attractive flower coloration.

The new Verbena originated from a cross-pollination made by the Inventor on Apr. 8, 2001 in Hikone, Shiga, Japan of a proprietary seedling selection of Verbena hybrida identified as code number VJL50-2, not patented, as the female, or seed, parent with a proprietary seedling selection of Verbena hybrida identified as code number VJL53-3, not patented, as the male, or pollen, parent. The new Verbena 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. 6, 2002.

Asexual reproduction of the new Verbena by terminal cuttings in a controlled environment in Bonsall, Calif. since Jun. 7, 2002 has shown that the unique features of this new Verbena are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar USBENA6201 has 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 ‘USBENA6201’. These characteristics in combination distinguish ‘USBENA6201’ as a new and distinct cultivar of Verbena:

• • 1. Outwardly to low spreading and relatively compact plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Red purple-colored flowers that are held above and beyond the foliage.
  • 6. Tolerant to Powdery Mildew.

Plants of the new Verbena can be compared to plants of the female parent selection. 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 outwardly spreading than plants of the female parent selection.
  • 2. Plants of the new Verbena are more vigorous 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 pink-colored flowers.
  • 4. Plants of the new Verbena are tolerant to Powdery Mildew whereas plants of the female parent selection are susceptible to Powdery Mildew.

Plants of the new Verbena can be compared to plants of the male 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 flower earlier than plants of the male parent selection.
  • 2. Plants of the new Verbena and the male parent selection differ in flower color as plants of the male parent selection have reddish pink-colored flowers.

Plants of the new Verbena can be compared to plants of the Verbena cultivar Sunvp-su, disclosed in U.S. Plant Pat. No. 10,311. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed from plants of the cultivar Sunvp-su in the following characteristics:

• • 1. Plants of the new Verbena were more upright than and not as creeping as plants of the cultivar Sunvp-su.
  • 2. Plants of the new Verbena were more compact than plants of the cultivar Sunvp-su.
  • 3. Plants of the new Verbena were more freely and earlier flowering than plants of the cultivar Sunvp-su.
  • 4. Plants of the new Verbena and the cultivar Sunvp-su differed in flower color as plants of the cultivar Sunvp-su had red-colored flowers.

Plants of the new Verbena can be compared to plants of the Verbena cultivar Scarlena, disclosed in U.S. Plant Pat. No. 12,578. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed from plants of the cultivar Scarlena in the following characteristics:

• • 1. Plants of the new Verbena and the cultivar Scarlena differed in flower color as plants of the cultivar Scarlena had scarlet red-colored flowers.
  • 2. Plants of the new Verbena were tolerant to Powdery Mildew whereas plants of the cultivar Scarlena were susceptible to Powdery Mildew.
