Abstract

A new and distinct cultivar of Viburnum plant named ‘JWW1’, characterized by its narrowly upright plant habit; vigorous growth habit; freely branching habit; numerous white-colored flowers; and good garden performance.

Description

Botanical designation: Viburnum plicatum.
Cultivar denomination: ‘JWW1’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Viburnum plant, botanically known as Viburnum plicatum and hereinafter referred to by the name ‘JWW1’.
The new Viburnum plant originated from an open-pollination in 2002 of Viburnum plicatum ‘Pink Beauty’, not patented, as the female, or seed, parent with an unknown selection of Viburnum plicatum as the male, or pollen, parent. The new Viburnum plant was discovered and selected by the Inventor in 2005 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Hazerswoude-Dorp, The Netherlands.
Asexual reproduction of the new Viburnum plant by softwood cuttings in a controlled environment in Hazerswoude-Dorp, The Netherlands since 2006 has shown that the unique features of this new Viburnum plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Viburnum have 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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘JWW1’. These characteristics in combination distinguish ‘JWW1’ as a new and distinct cultivar of Viburnum plant:
    • 1. Narrowly upright plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Numerous white-colored flowers.
    • 5. Good garden performance.
Plants of the new Viburnum can be compared to plants of the female parent, ‘Pink Beauty’. Plants of the new Viburnum differ from plants of ‘Pink Beauty’ in the following characteristics:
    • 1. Plants of the new Viburnum are more upright than and not as spreading as plants of ‘Pink Beauty’.
    • 2. Plants of the new Viburnum are more vigorous than plants of ‘Pink Beauty’.
    • 3. Plants of the new Viburnum and ‘Pink Beauty’ differ in flower color as plants of ‘Pink Beauty’ have pink-colored flowers.
Plants of the new Viburnum can be compared to plants of the Viburnum plicatum ‘Watanabe’, not patented. In side-by-side comparisons, plants of the new Viburnum differ from plants of ‘Watanabe’ in the following characteristics:
    • 1. Plants of the new Viburnum are more vigorous than plants of ‘Watanabe’.
    • 2. Plants of the new Viburnum root faster and easier than plants of ‘Watanabe’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Viburnum 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 Viburnum plant.
The photograph on the first sheet is a side perspective view of a typical plant of ‘JWW1’ grown in a container.
The photograph at the top of the second sheet is a close-up view of a typical inflorescence of ‘JWW1’.
The photograph at the bottom of the second sheet is a close-up view of a typical leaf of ‘JWW1’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants of the new Viburnum grown during the spring in 19-cm containers in a cold frame in Hazerswoude-Dorp, The Netherlands and under conditions which closely approximate commercial Viburnum production. During the production of the plants, day temperatures ranged from 15° C. to 25° C. and night temperatures ranged from 4° C. to 14° C. Plants were 18 months old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
