Description

Botanical designation: Weigela florida.

Cultivar denomination: ‘SMNWFBGV’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE

The Inventor/Applicant and Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Weigela plant, botanically known as Weigela florida and hereinafter referred to by the name ‘SMNWFBGV’.

The new Weigela plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to develop new compact and remontant-flowering Weigela plants with attractive flower colors.

The new Weigela plant is a naturally-occurring branch mutation of an unnamed proprietary seedling selection of Weigela florida, not patented. The new Weigela plant was discovered and selected by the Inventor on a single plant within a population of plants of the seedling selection in a controlled environment in Grand Haven, Mich. during the summer of 2013.

Asexual reproduction of the new Weigela plant by softwood stem cuttings since 2016 in Grand Haven, Mich. has shown that the unique features of this new Weigela plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Weigela have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘SMNWFBGV’. These characteristics in combination distinguish ‘SMNWFBGV’ as a new and distinct Weigela plant:

• • 1. Relatively compact, upright to outwardly spreading and uniformly mounding plant habit.
  • 2. Freely branching habit; dense and bushy appearance.
  • 3. Variegated leaves with olive green-colored centers surrounded with dark reddish brown-colored margins.
  • 4. Freely flowering habit.
  • 5. Purplish red-colored flowers that do not fully open and remain bud-like.
  • 6. Good garden performance.

In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Weigela differ primarily from plants of the mutation parent in leaf color as plants of the new Weigela have variegated leaves whereas plants of the mutation parent have non-variegated leaves.

Plants of the new Weigela can be compared to plants of the Weigela florida ‘Kolmagira’, disclosed in U.S. Plant Pat. No. 20,384. In side-by-side comparisons plants of the new Weigela differ primarily from plants of ‘Kolmagira’ in the following characteristics:

• • 1. Plants of the new Weigela have variegated leaves with olive green-colored centers surrounded with dark reddish brown-colored margins whereas plants of ‘Kolmagira’ have variegated leaves with yellow green and dark green-colored centers with purple-colored margins.
  • 2. Plants of the new Weigela have flowers that do not fully open whereas plants of ‘Kolmagira’ have flowers which fully open.

Plants of the new Weigela can also be compared to plants of the Weigela florida ‘SMNWFMS’, disclosed in U.S. Plant Pat. No. 26,922. In side-by-side comparisons plants of the new Weigela differ primarily from plants of ‘SMNWFMS’ in the following characteristics:

• • 1. Plants of the new Weigela have variegated leaves with olive green-colored centers surrounded with dark reddish brown-colored margins whereas plants of ‘SMNWFMS’ have non-variegated leaves that are dark burgundy to almost black in color.
  • 2. Plants of the new Weigela have flowers that do not fully open whereas plants of ‘SMNWFMS’ have flowers which fully open.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Weigela 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 Weigela plant.

The photograph on the first sheet (FIG. 1) is a side perspective view of a typical plant of ‘SMNWFBGV’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical flowering branch of ‘SMNWFBGV’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and the following description were grown during the spring and early summer in three-gallon containers in a polypropylene-covered greenhouse in Grand Haven, Mich. and under cultural practices typical of commercial Weigela production. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from 5° C. to 10° C. Plants of the new Weigela were two years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
