Ruscus plant named ‘Christmas Berry’

Abstract

A new and distinct cultivar of Ruscus plant named ‘Christmas Berry’, characterized by its upright plant habit; glossy green-colored cladophylls; numerous glossy and bright red-colored fruits; and good garden performance.

Description

Botanical designation: Ruscus aculeatus.

Cultivar denomination: ‘Christmas Berry’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Ruscus plant, botanically known as Ruscus aculeatus, and hereinafter referred to by the name ‘Christmas Berry’.

The new cultivar is a chance seedling from an open-pollination of unknown selections of Ruscus aculeatus. The new Ruscus was discovered and selected as a single plant by the Inventor on Aug. 10, 2003 in a controlled environment in North Co., Dublin, Ireland.

Asexual reproduction of the new Ruscus by divisions since Aug. 10, 2003 in North Co., Dublin, Ireland, has shown that the unique features of this new Ruscus are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Christmas Berry’. These characteristics in combination distinguish ‘Christmas Berry’ as a new and distinct cultivar:

• • 1. Upright plant habit.
  • 2. Glossy green-colored cladophylls.
  • 3. Numerous glossy and bright red-colored fruits.
  • 4. Good garden performance.

Plants of the new Ruscus can be compared to plants of the Ruscus cultivar Sparkler, not patented. In side-by-side comparisons conducted in North Co., Dublin, Ireland, plants of the new Ruscus differed from plants of the cultivar Sparkler in the following characteristics:

• • 1. Plants of the new Ruscus were more vigorous and denser than plants of the cultivar Sparkler.
  • 2. Plants of the new Ruscus had shinier, brighter and darker green-colored leaves than plants of the cultivar Sparkler.
  • 3. Plants of the new Ruscus had more berries per cladophyll than plants of the cultivar Sparkler.
  • 4. Plants of the new Ruscus and the cultivar Sparkler differed in fruit color as plants of the cultivar Sparkler had purple-colored fruits.

Plants of the new Ruscus can also be compared to plants of the Ruscus cultivar John Redmond, not patented. In side-by-side comparisons conducted in North Co., Dublin, Ireland, plants of the new Ruscus differed from plants of the cultivar John Redmond in the following characteristics:

• • 1. Plants of the new Ruscus were more vigorous and denser than plants of the cultivar John Redmond.
  • 2. Plants of the new Ruscus had shinier, brighter and darker green-colored leaves than plants of the cultivar John Redmond.
  • 3. Plants of the new Ruscus had more berries per cladophyll than plants of the cultivar John Redmond.
  • 4. Plants of the new Ruscus and the cultivar John Redmond differed in fruit color as plants of the cultivar John Redmond had dark red-colored fruits.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Ruscus, showing the colors as true as it is reasonably possibly 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 Ruscus.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Christmas Berry’ grown in a container.

The photograph at the top of the second sheet is a close-up view of typical fruits of ‘Christmas Berry’.

The photograph at the bottom of the second sheet is a close-up view of a typical flowers and leaves of ‘Christmas Berry’.

DETAILED BOTANICAL DESCRIPTION

The new Ruscus has 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 aforementioned photographs, following observations and measurements describe plants grown in 2-liter containers in Boskoop, The Netherlands, in an outdoor nursery and under commercial production practices. Plants used for the photographs and the description were about two years old. The photographs and description were taken during the fall with day temperatures ranging from 7° to 15° C. and night temperatures ranging from −4° C. to 8° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
