USPP35933P2 - Tradescantia plant named ‘EC-TRAD-2303’ - Google Patents

Abstract

A new and distinct cultivar of Tradescantia plant named ‘EC-TRAD-2303’ is disclosed, characterized by bright white and green variegated foliage, with large, pointed, elongated leaves. White flowers bloom continuously when grown indoors. The new variety is a Tradescantia, typically used as an ornamental plant.

Description

Latin name of the genus and species: Tradescantia cerinthoides.

Variety denomination: ‘EC-TRAD-2303’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a naturally-occurring branch mutation of Tradescantia cerinthoides ‘200409’, unpatented. The new variety was discovered by the inventor in March of 2021, at a nursery in Sappemeer, the Netherlands.

Asexual reproduction of the new cultivar ‘EC-TRAD-2303’ by stem-top cuttings was first performed at the same nursery in Sappemeer, the Netherlands in April 2021, and has shown that the unique features of this cultivar are stable and reproduced true to type through successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘EC-TRAD-2303’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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-TRAD-2303’. These characteristics in combination distinguish ‘EC-TRAD-2303’ as a new and distinct Tradescantia cultivar:

• • 1. Bright white and fresh green variegated leaf-color.
  • 2. Large, elongated leaves, pointed to the end.
  • 3. Strong and thick stems.

PARENT COMPARISON

Plants of the new cultivar ‘EC-TRAD-2303’ are similar to plants of the parent variety in most horticultural characteristics, however, plants of the new cultivar ‘EC-TRAD-2303’ differ from in the following characteristics:

• • 1. Leaf color of the new variety is white and green, while the leaf color of the parent variety is white and darker green.
  • 2. Leaves of the new variety are larger and more elongated than leaves of the parent variety.
  • 3. Stems of the new variety are stronger and thicker than stems of the parent variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘EC-TRAD-2303’ are similar to plants of the commercial variety Tradescantia albiflora ‘Nanouk’, U.S. Plant Pat. No. 29,711. However, plants of the new cultivar differ in the following characteristics:

• • 1. Leaf color of the new variety is white and green, while the leaf color of this comparator is purple, green and greyed-green.
  • 2. Leaves of the new variety are larger than leaves of this comparator.

Plants of the new cultivar ‘EC-TRAD-2303’ are similar to plants of the unpatented Tradescantia cerinthoides ‘EC-TRADE-2011’ U.S. Plant Pat. No. 33,788. However, plants of the new cultivar differ in the following characteristics:

• • 1. Leaf color of the new variety is white and green, while the leaf color of this comparator is green with pink stripes.
  • 4. Leaves of the new variety are larger than leaves of this comparator.
  • 5. Plants of the new variety are less compact than plants of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘EC-TRAD-2303’ grown in a glass greenhouse in Sappemeer, the Netherlands. The plant is approximately 8 weeks of age.

FIG. 2 illustrates a close up of the foliage.

FIG. 3 illustrates flowers.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
