plant named ‘VERWEIG9’

- Spring Meadow Nursery

A new and distinct cultivar of Weigela plant named ‘VERWEIG9’ is disclosed, characterized by dynamic foliage color, changing from green with a bonze tint in the Spring to orange-bronze in the Summer, and bright red in the Fall. Plants are compact and globose in habit. Flowers are bright pink. The new variety is a Weigela, normally produced as an outdoor garden plant.

Description

Latin name of the genus and species: Weigela florida.

Variety denomination: ‘VERWEIG9’.

BACKGROUND OF THE INVENTION

The new Weigela cultivar is a product of open pollination conducted by the inventor in Hazerswoude, the Netherlands. The objective of the breeding program was to produce new Weigela plants with novel foliage colors and dwarf plant habits. The crossing resulting in this new variety was made during the Summer 2013.

The seed parent is the variety Weigela florida ‘Verwof 1’, U.S. Plant Pat. No. 30,866. The pollen parent is the unpatented proprietary Weigela florida variety referred to as ‘Weigela bv005’. The new variety was identified as a potentially interesting selection in Summer 2015, at a nursery in Hazerswoude, the Netherlands.

Asexual reproduction of the new cultivar ‘VERWEIG9’ by softwood cuttings was first performed in the Summer of 2015, at a nursery in Hazerswoude, the Netherlands. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘VERWEIG9’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘VERWEIG9’. These characteristics in combination distinguish ‘VERWEIG9’ as a new and distinct Weigela cultivar;

    • 1. Dynamic foliage color, changing from green with a bonze tint in the Spring to orange-bronze in the Summer, and bright red in the Fall.
    • 2. Compact growth habit.
    • 3. Globose plant form.
    • 4. Bright pink flowers.

PARENT COMPARISON

Plants of the new cultivar ‘VERWEIG9’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘VERWEIG9’ differ in the following;

    • 1. Foliage of the new cultivar turns bright red in the Fall; foliage of the seed parent develops only red leaf margins in the Fall.
    • 2. Foliage of the new variety turns bronze-orange in Summer; foliage of the seed parent transitions directly from lime green to green with brown-red margins.

Plants of the new cultivar ‘VERWEIG9’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘VERWEIG9’ differ in the following;

    • 1. Foliage of the new cultivar is not variegated; foliage of the pollen parent is variegated.
    • 2. Mature plants of the new variety are shorter than mature plants of the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘VERWEIG9’ can be compared to the commercial variety Weigela ‘Wings of Fire’, U.S. Plant Pat. No. 21,920. These varieties are similar in most horticultural characteristics, however ‘VERWEIG9’ differs in the following;

    • 1. New cultivar has leaves with a most flat aspect; foliage of this comparator is strongly concave.
    • 2. Foliage of the new variety transitions from dark green to bronze to bright red; foliage of this comparator transitions from lime green to dark red.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color typical Spring foliage color of ‘VERWEIG9’ during Spring.

FIG. 2 illustrates typical plants grown in a 2-gallon pot, at about 1.5 years of age, in the Summer with typical Summer foliage coloration.

FIG. 3 illustrates in full color typical plants of ‘VERWEIG9’ with typical fall foliage color in a ground bed at about 2 years of age.

FIG. 4 illustrates a close-up view of the flowers.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
