Tradescantia plant named ‘Pink Chablis’

Abstract

A new and distinct cultivar of Tradescantia plant named ‘Pink Chablis’, characterized by its upright and outwardly spreading plant habit; freely flowering habit; and light red purple and white bi-colored petals with ruffled margins.

Description

Botanical classification/cultivar designation: Tradescantia×andersoniana cultivar Pink Chablis.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Tradescantia plant, botanically known as Tradescantia×andersoniana, and hereinafter referred to by the name ‘Pink Chablis’.

The new Tradescantia originated from a cross-pollination of two unknown selections of Tradescantia×andersoniana, not patented. The new Tradescantia was discovered and selected as a single flowering plant by the Inventor in a controlled environment in Warmond, The Netherlands in 1999 from the resultant progeny of the cross-pollination.

Asexual reproduction of the new cultivar by cuttings at Warmond, The Netherlands since 2000, has shown that the unique features of this new Tradescantia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Pink Chablis have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Pink Chablis’. These characteristics in combination distinguish ‘Pink Chablis’ as a new and distinct Tradescantia cultivar:

• • 1. Upright and outwardly spreading plant habit.
  • 2. Freely flowering habit.
  • 3. Light red purple and white bi-colored petals with ruffled margins.

Plants of the new Tradescantia can be compared to plants of the Tradescantia cultivar Sweet Kate, not patented. In side-by-side comparisons conducted in Warmond, The Netherlands, plants of the new Tradescantia differed from plants of the cultivar Sweet Kate in the following characteristics:

• • 1. Plants of the new Tradescantia were slightly shorter than plants of the cultivar Sweet Kate.
  • 2. Plants of the new Tradescantia had darker green-colored foliage than plants of the cultivar Sweet Kate.
  • 3. Plants of the new Tradescantia and the cultivar Sweet Kate differed in flower color as plants of the cultivar Sweet Kate had blue-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 Tradescantia.

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

The photograph at the center of the sheet is a close-up view of a typical flower of ‘Pink Chablis’.

The photograph at the bottom of the sheet is a close-up view of the upper surface of a typical leaf of ‘Pink Chablis’.

DETAILED BOTANICAL DESCRIPTION

Plants shown in the aforementioned photographs and used in the following description were grown under conditions which closely approximate commercial production conditions during the summer in an outdoor nursery in Warmond, The Netherlands. Plants were about two years old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 18 to 32° C. and night temperatures ranged from 4 to 18° C.
