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 ‘SMNWFGC’.

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 freely flowering Weigela plants with dark-colored leaves and white-colored flowers.

The new Weigela plant originated from an open-pollination in 2016 in Grand Haven, Mich. of Weigela florida ‘Granitini’, not patented, as the female, or seed, parent with an unknown selection of Weigela florida as the male, or pollen, parent. The new Weigela plant was discovered and selected by the Inventor in 2018 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.

Asexual reproduction of the new Weigela plant by softwood stein cuttings since 2018 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 ‘SMNWFGC’. These characteristics in combination distinguish ‘SMNWFGC’ as a new and distinct Weigela plant:

• • 1. Upright to outwardly spreading and uniformly mounding plant habit.
  • 2. Freely branching habit; dense and bushy appearance.
  • 3. Leaves that are dark purple to dark reddish brown in color.
  • 4. Freely flowering habit.
  • 5. Light yellow green-colored flower buds and white-colored flowers.
  • 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 female parent, ‘Granitini’, in the following characteristics:

• • 1. Plants of the new Weigela have darker-colored leaves than plants of ‘Granitini’.
  • 2. Plants of the new Weigela have smaller flowers than plants of ‘Granitini’.
  • 3. Plants of the new Weigela have white-colored flowers whereas plants of ‘Granitini’ have white-colored flowers that are tinged with pink.

Plants of the new Weigela can also be compared to plants of the Weigela florida ‘Velda’, disclosed in U.S. Plant Pat. No. 26,842. In side-by-side comparisons plants of the new Weigela differ primarily from plants of ‘Velda’ in the following characteristics:

• • 1. Plants of the new Weigela have darker-colored leaves than plants of ‘Velda’.
  • 2. Plants of the new Weigela are more freely flowering than plants of ‘Velda’.
  • 3. Flower buds of plants of the new Weigela are brighter yellow green in color than flower buds of plants of ‘Velda’.
  • 4. Flowers of plants of the new Weigela are white in color whereas flowers of plants of ‘Velda’ are white in color with a yellow orange-colored streak in the throat.

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 ‘SMNWFGC’ grown in an outdoor nursery.

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

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and the following description were grown during the spring and summer in ground beds in an outdoor nursery and 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.
