Torenia plant named ‘Sunrenibebu’

Abstract

A new and distinct cultivar of Torenia plant named ‘Sunrenibebu’ characterized by its compact and mounding to trailing plant habit; freely branching habit; freely flowering habit; long flowering period; light violet-colored flowers; and good garden performance.

Description

Botanical designation: Torenia sp.

Cultivar denomination: ‘Sunrenibebu’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Torenia, botanically known as Torenia sp. and hereinafter referred to by the name ‘Sunrenibebu’.

The new Torenia is a whole plant mutation of a proprietary selection of Torenia sp. identified as code number TH4, not patented. The new Torenia was discovered and selected by the Inventors as a single plant in a controlled greenhouse environment in Higashiomi, Shiga, Japan in March, 2006.

Asexual reproduction of the new Torenia by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since October, 2006, has shown that the unique features of this new Torenia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Torenia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature 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 ‘Sunrenibebu’. These characteristics in combination distinguish ‘Sunrenibebu’ as a new and distinct cultivar of Torenia:

• • 1. Compact and mounding to trailing plant habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Long flowering period.
  • 5. Light violet-colored flowers.
  • 6. Good garden performance.

Plants of the new Torenia differ primarily from plants of the parent selection in flower color as plants of the parent selection have darker violet-colored flowers. In addition, plants of the new Torenia are smaller than plants of the parent selection.

Plants of the new Torenia can also be compared to plants of Torenia sp. ‘Sunrenicopalave’, disclosed in U.S. Plant Pat. No. 17,001. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Torenia and ‘Sunrenicopalave’ differed in the following characteristics:

• • 1. Plants of the new Torenia were narrower than plants of ‘Sunrenicopalave’.
  • 2. Plants of the new Torenia had shorter internodes than plants of ‘Sunrenicopalave’.
  • 3. Plants of the new Torenia had narrower leaves than plants of ‘Sunrenicopalave’.
  • 4. Plants of the new Torenia had smaller flowers than plants of ‘Sunrenicopalave’.
  • 5. Plants of the new Torenia and ‘Sunrenicopalave’ differed in flower color as plants of ‘Sunrenicopalave’ had darker-colored flowers.
  • 6. Plants of the new Torenia had shorter peduncles than plants of ‘Sunrenicopalave’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Torenia, 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 colors of the new Torenia.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunrenibebu’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flower, flower buds and leaves of ‘Sunrenibebu’.
