plant named ‘EC-TRADE-1809’

Abstract

A new cultivar of Tradescantia plant named ‘EC-TRADE-1809’ that is characterized by silver and purple leaves that have a sharp definition between the silver and purple areas, short internodes and a compact habit.

Description

Botanical classification: Tradescantia zebrina.

Variety denomination: ‘EC-TRADE-1809’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Tradescantia plant botanically known as Tradescantia zebrina and hereinafter referred to by the cultivar name ‘EC-TRADE-1809’.

‘EC-TRADE-1809’ originated from the crossing of the female or seed parent, an unnamed Tradescantia zebrina cultivar and the male or pollen parent, an unnamed Tradescantia zebrina cultivar. The crossing was conducted in 2015 in Sappemeer, Netherlands. The resulting seeds were subsequently planted and grown. The cultivar ‘EC-TRADE-1809’ was selected by the inventor in 2016 in a controlled environment as a single plant within the progeny of the stated cross in a cultivated area of Sappemeer, Netherlands.

Asexual reproduction of the new cultivar ‘EC-TRADE-1809’ first occurred by stem cuttings in 2016 in Sappemeer, Netherlands. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Tradescantia cultivar ‘EC-TRADE-1809’. These traits in combination distinguish ‘EC-TRADE-1809’ as a new and distinct cultivar apart from other existing varieties of Tradescantia known by the inventor.

• • 1. Tradescantia ‘EC-TRADE-1809’ exhibits silver and purple leaves that have a sharp definition between the silver and purple areas.
  • 2. Tradescantia ‘EC-TRADE-1809’ exhibits short internodes.
  • 3. Tradescantia ‘EC-TRADE-1809’ exhibits a compact habit.

The closest comparison cultivars are plants of the species Tradescantia pendula (not patented) and plants of the species Tradescantia carnivale (not patented). ‘EC-TRADE-1809’ is distinguishable from Tradescantia pendula by the following characteristics:

• • 1. Tradescantia ‘EC-TRADE-1809’ exhibits silver and purple leaves that have a sharp definition between the silver and purple areas. In comparison, the leaves of Tradescantia pendula are light and dark purple in color.
  • 2. The leaves of Tradescantia ‘EC-TRADE-1809’ are wider than the leaves of Tradescantia pendula. The leaves of Tradescantia pendula are more elongated than the leaves of ‘EC-TRADE-1809’.

‘EC-TRADE-1809’ is distinguishable from Tradescantia carnivale by the following characteristics:

• • 1. Tradescantia ‘EC-TRADE-1809’ exhibits silver and purple leaves that have a sharp definition between the silver and purple areas. In comparison, the leaves of Tradescantia carnivale are green and pink in color.
  • 2. The leaves of Tradescantia ‘EC-TRADE-1809’ are larger in length and width than the leaves of Tradescantia carnivale.

‘EC-TRADE-1809’ is distinguishable from the female parent plant, by the following characteristics:

• • 1. The leaves of ‘EC-TRADE-1809’ have a sharp definition between the silver and purple areas. In comparison, the leaves of the female parent plant do not have a sharp definition between the silver and purple areas.
  • 2. The internodes of ‘EC-TRADE-1809’ are shorter than the internodes of the female parent plant.

‘EC-TRADE-1809’ is distinguishable from the male parent plant by the following characteristics:

• • 1. The leaves of ‘EC-TRADE-1809’ have a sharp definition between the silver and purple areas. In comparison, the leaves of the male parent plant do not have a sharp definition between the silver and purple areas.
  • 2. The internodes of ‘EC-TRADE-1809’ are shorter than the internodes of the male parent plant.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Tradescantia ‘EC-TRADE-1809’. The photograph shows an overall view of an 18 week old plant. The photograph was 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.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Tradescantia cultivar named ‘EC-TRADE-1809’. Data was collected in Sappemeer, Netherlands from 18 week old plants grown in a glass greenhouse in 10.5 cm. diameter containers. The time of year was Fall and the temperature range was 18-21 degrees Centigrade during the day and 18-21 degrees Centigrade at night. The light level was natural light level. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2015 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘EC-TRADE-1809’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
