Symphoricarpos plant named ‘Bokrabright’

Abstract

A new and distinct cultivar of Symphoricarpos plant named ‘Bokrabright’, characterized by its upright and outwardly spreading plant habit; freely branching growth habit; whitish-colored fruits; and good postproduction longevity.

Description

Botanical classification/cultivar designation: Symphoricarpos albus cultivar Bokrabright.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Symphoricarpos plant, botanically known as Symphoricarpos albus, commercially used as cut stems with fruits, and hereinafter referred to by the name ‘Bokrabright’.

The new Symphoricarpos is a product of a planned breeding program conducted by the Inventor in Boskoop, The Netherlands. The objective of the breeding program was to develop cut Symphoricarpos cultivars with attractive fruit coloration.

The new cultivar originated from a cross made by the Inventor in 1996 of two unidentified proprietary seedling selections, not patented. The cultivar Bokrabright was discovered and selected by the Inventor in 1998 as a flowering plant within the progeny of the stated cross in a controlled environment in Boskoop, The Netherlands.

Asexual reproduction of the new Symphoricarpos by terminal cuttings taken at Boskoop, The Netherlands, has shown that the unique features of this new Symphoricarpos 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 ‘Bokrabright’. These characteristics in combination distinguish ‘Bokrabright’ as a new. and distinct cultivar:

1. Upright and outwardly spreading plant habit.

2. Freely branching growth habit.

3. Whitish-colored fruits.

4. Good postproduction longevity.

Plants of the new Symphoricarpos differ from plants of the parent seedling selections primarily in growth habit and fruit coloration.

Plants of the new Symphoricarpos can be compared to plants of the Symphoricarpos cultivar White Hedge, not patented. In side-by-side comparisons conducted in Boskoop, The Netherlands, plants of the new Symphoricarpos differed from plants of the cultivar White Hedge in the following characteristics:

1. Plant of the new Symphoricarpos were more upright than plants of the cultivar White Hedge.

2. Plants of the new Symphoricarpos had larger fruits than plants of the cultivar White Hedge.

DETAILED BOTANICAL DESCRIPTION

The new Symphoricarpos has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown in Boskoop, The Netherlands, in an outdoor nursery and under commercial production practices. Plants were about two years old and pruned annually during the spring. The photographs and description were taken during the summer when outdoor day temperatures ranged from 7 to 30° C. and night temperatures ranged from 3 to 16° 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.
