plant named ‘JWW 5’

Abstract

A new cultivar of Viburnum plicata plant named ‘JWW 5’ that is characterized by its dense and distinct upright plant habit, its sterile flowers that blushed pink in color, its young stems that are red in color, and its well-developed fruits that are large, glossy and red in color.

Description

Botanical classification: Viburnum plicatum.

Variety denomination: ‘JWW 5’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Viburnum plicatum. The new Viburnum will hereafter by its cultivar name, ‘JWW 5’. ‘JWW 5’ is a new cultivar of deciduous shrub grown for use as an ornamental landscape plant.

The new cultivar is the result of a controlled breeding program conducted by the Inventor in Hazerswoude-Dorp, The Netherlands. The objective of the breeding program was to develop a new cultivar of Viburnum plicatum that is pink flowering with an upright plant habit.

The new cultivar arose from a cross made by the Inventor in Barmstedt, Germany in spring of 2009 between Viburnum plicatum ‘JWW1’ (U.S. Plant Pat. No. 22,326) as the female parent and Viburnum plicatum ‘Pink Beauty’ (not patented) as the male parent. The Inventor selected ‘HJWW5’ as a single unique plant amongst the seedlings that resulted from the above cross in spring of 2011.

Asexual propagation of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in June of 2011 in Hazerswoude-Dorp, The Netherlands. Asexual propagation by softwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘JWW 5’ as a unique cultivar of Viburnum.

• • 1. ‘JWW 5’ exhibits a dense and distinct upright plant habit.
  • 2. ‘JWW 5’ exhibits sterile flowers that blushed pink in color and fade to white.
  • 3. ‘JWW 5’ exhibits young stems that are red in color.
  • 4. ‘JWW 5’ exhibits well-developed fruits that are large, glossy and red in color.
    ‘JWW1’, the female parent of ‘JWW 5’, differs from ‘JWW 5’ in having sterile flowers that are white in color and in producing less fruits. ‘Pink Beauty’, the male parent of ‘JWW 5’, differs from ‘JWW 5’ in having sterile flowers that deeper pink in color, a less upright and broader plant habit, and in producing smaller fruits. ‘JWW 5’ can be most closely compared to Viburnum plicatum cultivars ‘Lanarth’ (not patented) and ‘Watanabe’ (not patented). ‘Lanarth’ is similar to ‘JWW 5’ in flower form and in freely producing fruit. ‘Lanarth’ differs from ‘JWW 5’ in having a more open and less upright plant habit, in having white sterile flowers, and in producing smaller fruit that ripen earlier in the season. ‘Watanabe’ is similar to ‘JWW 5’ in flower form and plant habit. ‘Watanabe’ differs from ‘JWW 5’ in having a slower growth rate and in having white sterile flowers.
