Description

Botanical designation: Tradescantia cerinthoides.

Cultivar denomination: ‘EC-TRADE-2011’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Eden Collection B.V. of Sappemeer, The Netherlands on Sep. 4, 2020, application number 2020/2115. Foreign priority is not claimed to this application.

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Tradescantia plant, botanically known as Tradescantia cerinthoides and hereinafter referred to by the name ‘EC-TRADE-2011’.

The new Tradescantia plant is a product of a planned breeding program conducted by the Inventor in Sappemeer, The Netherlands. The objective of the breeding program was to create new compact Tradescantia plants with attractive and unique leaf coloration and good overall plant performance.

The new Tradescantia plant is a naturally-occurring branch mutation of an unnamed selection of Tradescantia cerinthoides, not patented. The new Tradescantia plant was discovered and selected by the Inventor on a single plant from within a population of plants of the patent selection in a controlled greenhouse environment in Sappemeer, The Netherlands in March, 2019.

Asexual reproduction of the new Tradescantia plant by terminal cuttings in a controlled greenhouse environment in Sappemeer, The Netherlands since April, 2019 has shown that the unique features of this new Tradescantia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Tradescantia have not been observed under all possible combinations of environmental conditions and cultural practices. 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 ‘EC-TRADE-2011’. These characteristics in combination distinguish ‘EC-TRADE-2011’ as a new and distinct Tradescantia plant:

• • 1. Uniform, compact and upright to broadly spreading plant habit.
  • 2. Freely branching habit; dense and bushy appearance.
  • 3. Strong and healthy leaves.
  • 4. Green-colored leaves with light purple-colored longitudinal stripes.
  • 5. Good postproduction and interiorscape performance.

Plants of the new Tradescantia and the parent selection differ primarily in leaf color as plants of the parent selection have solid green-colored leaves without light purple-colored stripes.

Plants of the new Tradescantia can also be compared to plants of the Tradescantia albiflora ‘Nanouk’, disclosed in U.S. Plant Pat. No. 29,711. In side-by-side comparisons, plants of the new Tradescantia and ‘Nanouk’ differ primarily in the following characteristics:

• • 1. Plants of the new Tradescantia are more compact than plants of ‘Nanouk’.
  • 2. Plants of the new Tradescantia have thinner stems than plants of ‘Nanouk’.
  • 3. Leaves of plants of the new Tradescantia are smaller than leaves of plants of ‘Nanouk’.
  • 4. Leaves of plants of the new Tradescantia are green in color with longitudinal light purple-colored stripes whereas leaves of plants of ‘Nanouk’ are green and greyed green in color with light purple-colored longitudinal stripes.

Plants of the new Tradescantia can also be compared to plants of the Tradescantia spathacea ‘Tricolor’, not patented. In side-by-side comparisons, plants of the new Tradescantia and ‘Tricolor’ differ primarily in the following characteristics:

• • 1. Plants of the new Tradescantia are more compact than plants of ‘Tricolor’.
  • 2. Plants of the new Tradescantia are more freely branching than plants of ‘Tricolor’.
  • 3. Leaves of plants of the new Tradescantia are smaller and broader than leaves of plants of ‘Tricolor’.
  • 4. Leaves of plants of the new Tradescantia are green in color with longitudinal light purple-colored stripes whereas leaves of plants of ‘Tricolor’ are green and greyed green in color with light purple-colored longitudinal stripes.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Tradescantia plant 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 Tradescantia plant.

The photograph on the first sheet (FIG. 1) comprises a side perspective view of a typical plant of ‘EC-TRADE-2011’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of typical leaves of ‘EC-TRADE-2011’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in 14-cm containers during the summer in a glass-covered greenhouse in Sappemeer, The Netherlands and under cultural practices typical of commercial Tradescantia production. During the production of the plants, day temperatures ranged from 18° C. to 21° C. and night temperatures ranged from 16° C. to 20° C. Plants were two months old when the photographs and description were taken.
