plant named ‘Verweig 8’

Abstract

A new cultivar of Weigela florida, ‘Verweig 8’, characterized by its vigorous growth habit, its compact plant habit, its free-branching habit, its foliage that is variegated with dark purplish green center and creamy white margins with the young foliage and growth tips tinged with pink, its floriferous and remontant blooming habit, and its flowers that are red-purple in color.

Description

Botanical classification: Weigela florida.

Variety denomination: ‘Verweig 8’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Weigela and will be referred to hereafter by its cultivar name, ‘Verweig 8’. ‘Verweig 8’ represents a new cultivar of Weigela, a deciduous shrub grown for landscape use.

The new cultivar was discovered by the Inventor on July of 2015 as a naturally occurring branch mutation of Weigela ‘Verweig’ (U.S. Plant Pat. No. 16,824) that was growing outdoors in a trial field in Hazerswoude-Dorp, The Netherlands.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings by the Inventor in July of 2015 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 are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Verweig 8’ as a unique cultivar of Weigela.

• • 1. ‘Verweig 8’ exhibits a vigorous growth habit.
  • 2. ‘Verweig 8’ exhibits a compact plant habit.
  • 3. ‘Verweig 8’ exhibits a free-branching habit.
  • 4. ‘Verweig 8’ exhibits foliage that is variegated with dark purplish green center and creamy white margins with the young foliage and growth tips tinged with pink.
  • 5. ‘Verweig 8’ exhibits a floriferous and remontant blooming habit.
  • 6. ‘Verweig 8’ exhibits flowers that are red-purple in color.

‘Verweig’, the parent plant of ‘Verweig 8’, differs from ‘Verweig 8’ in having a less vigorous growth habit and foliage that is less strongly variegation and more prone to leaf-burn. ‘Verweig 8’ can also be compared to the Weigela florida cultivars ‘Nana Variegata’ (not patented) and ‘Kolmagira’ (U.S. Plant Pat. No. 20,384). Both ‘Nana Variegata’ and ‘Kolmagira’ are similar to ‘Verweig 8’ in having variegated foliage. ‘Nana Variegata’ differs from ‘Verweig 8’ in having a less compact plant habit, young leaves and growing tips that are not tinged pink in color and leaves that have medium green centers and creamy white to white margins. ‘Kolmagira’ differs from ‘Verweig 8’ in having a less compact plant habit and leaves that have medium green centers and light yellow margins.
