Verbena plant named ‘Sunmariburare’

Abstract

A new and distinct cultivar of Verbena plant named ‘Sunmariburare’, characterized by its trailing and decumbent plant habit; vigorous and freely branching growth habit; attractive light red-colored flowers; freely and continuous flowering habit; long-lasting flowers; and good garden performance.

Description

Botanical designation: Verbena×hybrida.

Cultivar denomination: ‘Sunmariburare’.

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 cultivar name Sunmariburare.

The new Verbena is a product of a planned breeding program conducted by the Inventors in Hokuto, Yamanashi, Japan. The objective of the breeding program is to create new trailing Verbenas with large and attractive flowers.

The new Verbena originated from a self-pollination made by the Inventors in May, 1996 of a proprietary selection of Verbena×hybrida identified as code number H17-8, not patented. The new Verbena was selected as a single plant from the resulting progeny of the self-pollination by the Inventors in a controlled environment in Hokuto, Yamanashi, Japan.

Asexual reproduction of the new cultivar by terminal cuttings at Yokaichi, Shiga, Japan since October, 1998, has shown that the unique features of this new Verbena are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Sunmariburare have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunmariburare’. These characteristics in combination distinguish ‘Sunmariburare’ as a new and distinct cultivar of Verbena:

• • 1. Trailing and decumbent plant habit.
  • 2. Vigorous and freely branching growth habit.
  • 3. Attractive light red-colored flowers.
  • 4. Freely and continuous flowering habit.
  • 5. Long-lasting flowers.
  • 6. Good garden performance.

Compared to plants of the new Verbena, plants of the parent selection are more upright and not as trailing. In addition, plants of the new Verbena and the parent selection differ in flower color as plants of the parent selection have pink-colored flowers.

Plants of the new Verbena can be compared to plants of the cultivar Sunmariripi, disclosed in U.S. Plant Pat. No. 11,037. In side-by-side comparisons conducted in Yokaichi, Shiga, Japan, plants of the new Verbena differed from plants of the cultivar Sunmariripi in the following characteristics:

• • 1. Plants of the new Verbena were larger and had longer internodes than plants of the cultivar Sunmariripi.
  • 2. Plants of the new Verbena and the cultivar Sunmariripi differed in leaf shape.
  • 3. Plants of the new Verbena and the cultivar Sunmariripi differed in flower coloration as plants of the cultivar Sunmariripi had pink-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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 photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Verbena.

The photograph at the top of the sheet is a side perspective view of a typical plant of ‘Sunmariburare’.

The photograph at the bottom of the sheet is a close-up view of typical inflorescences of ‘Sunmariburare’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown during the summer in Higashiomi, Shiga, Japan in an outdoor nursery and under commercial production practices. Plants were grown in 15-cm containers and were about four months old when the photographs and description were taken. During the production of the plants, day temperatures averaged 25° C. and night temperatures averaged 15° C. Plants were pinched one time in the spring. 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.
