‘Wevo2’

Abstract

A new cultivar of Abelia×grandiflora named ‘Wevo2’ that is characterized by its foliage that is shiny and medium green in color and variegated with a thin white margin; the variegation is retained from spring until winter, its white flowers, and its dwarf and upright spreading plant habit.

Description

Botanical classification: Abelia×grandiflora.

Varietal denomination: ‘Wevo2’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Abelia×grandiflora and will be referred to hereafter by its cultivar name, ‘Wevo2’. ‘Wevo2’ represents a new Abelia, a semi-evergreen shrub grown for landscape use.

The Inventor discovered the new cultivar in summer of 2007 as a naturally occurring branch mutation of Abelia×grandiflora ‘Abelops’ (U.S. Pat. No. 20,961) in a container at his nursery in Reeuwijk, The Netherlands.

Asexual reproduction of the new cultivar was first accomplished by stem cutting by the inventor in Reeuwijk, The Netherlands in 2007. It has been 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 ‘Wevo2’ from all other varieties of Abelia known to the inventor.

• • 1. ‘Wevo2’ exhibits foliage that is shiny and medium green in color and variegated with a thin white margin; the variegation is retained from spring until winter.
  • 2. ‘Wevo2’ exhibits white flowers.
  • 3. ‘Wevo2’ exhibits a dwarf and upright spreading plant habit; reaching about 1 m in height when mature.

‘Abelops’, the parent plant of ‘Wevo2’, differs from ‘Wevo2’ in having variegated foliage in which the white margin is wider, in having foliage that turns reddish in autumn, and in having flowers that are pinkish white in color. ‘Wevo2’ can also be most compared to the cultivar ‘Kaleidoscope’ (U.S. Plant Pat. No. 16,988), ‘Conti’ (not patented) and ‘Sunrise’ (not patented). ‘Kaleidoscope’ differs from ‘Wevo2’ in having variegated foliage with green centers and wide yellow margins early in season with the leaves flushed with orange and red in autumn. ‘Conti’ differs from ‘Wevo2’ in having foliage that is variegated with broader white margins that are flushed with pink on new growth, and in having flowers that are pinkish white in color. ‘Sunrise’ differs from ‘Wevo2’ in having variegated foliage with wider margins that are golden yellow in color and turn to creamy white as the leaves mature.
