Torenia plant named ‘Sunreniripin’

Abstract

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

Description

Botanical designation: Torenia sp.

Cultivar denomination: ‘Sunreniripin’.

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 ‘Sunreniripin’.

The new Torenia is a whole plant mutation of a proprietary selection of Torenia sp. identified as code number TH3, 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, 2004.

Asexual reproduction of the new Torenia by vegetative cuttings in a controlled environment in Higashiomi, Shiga, Japan since October, 2004, has shown that the unique features of this new Torenia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Sunreniripin’ has 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 ‘Sunreniripin’. These characteristics in combination distinguish ‘Sunreniripin’ 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. Dark and light red purple-colored flowers.
  • 6. Good garden performance.

Compared to plants of the parent selection, plants of the new Torenia are smaller and differ in leaf color. In addition, plants of the new Torenia and the parent selection differ in flower color as plants of the parent selection have violet-colored flowers with violet-colored centers.

Plants of the new Torenia can also be compared to plants of the cultivar Sunrenipiho, disclosed in a U.S. Plant Pat. No. 10,118. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Torenia and the cultivar Sunrenipiho differed in the following characteristics:

• • 1. Plants of the new Torenia were smaller and had shorter internodes than plants of the cultivar Sunrenipiho.
  • 2. Plants of the new Torenia had broader leaves than plants of the cultivar Sunrenipiho.
  • 3. Plants of the new Torenia had larger flowers than plants of the cultivar Sunrenipiho.
  • 4. Plants of the new Torenia and the cultivar Sunrenipiho differed in flower color.

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 ‘Sunreniripin’ grown in a container.

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

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Higashiomi, Shiga, Japan, under commercial practice during the winter in a polyethylene-covered greenhouse with day temperatures averaging 23° C. and night temperatures averaged 13° C. Plants had been growing for about five months when the photographs and description were taken.
