Abstract

A new and distinct cultivar of Weigela plant named ‘SMNWFG’, characterized by its upright to outwardly spreading and uniformly mounding plant habit; vigorous growth habit and rapid growth rate; freely branching habit; dense and bushy appearance; leaves that are dark green in color tinged with dark reddish brown; freely and remontant flowering habit; bright purplish red-colored flowers; and good garden performance.

Description

Botanical designation: Weigela florida.

Cultivar denomination: ‘SMNWFG’.

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 ‘SMNWFG’.

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 Weigela plants with dark-colored leaves and freely and remontant flowering habit.

The new Weigela plant originated from an open-pollination in 2016 in Grand Haven, Mich. of an unnamed proprietary selection of Weigela florida, not patented, as the female, or seed, parent with an unknown proprietary 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 stem 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 ‘SMNWFG’. These characteristics in combination distinguish ‘SMNWFG’ as a new and distinct Weigela plant:

- 1. Upright to outwardly spreading and uniformly mounding plant habit.
- 2. Vigorous growth habit and rapid growth rate.
- 3. Freely branching habit; dense and bushy appearance.
- 4. Leaves that are dark green in color tinged with dark reddish brown.
- 5. Freely and remontant flowering habit.
- 6. Bright purplish red-colored flowers.
- 7. Good garden performance.

In side-by-side comparisons, plants of the new Weigela differ primarily from plants of the female parent selection in the following characteristics:

- 1. Leaves of plants of the new Weigela are dark green in color tinged with dark reddish brown whereas leaves of plants of the female parent selection are dark green in color, but not as darkly tinged.
- 2. Plants of the new Weigela flower more remontantly than plants of the female parent selection.

Plants of the new Weigela can also be compared to plants of the Weigela florida ‘SMWFDFPD’, disclosed in U.S. Plant Pat. No. 32,223. In side-by-side comparisons plants of the new Weigela differ primarily from plants of ‘SMWFDFPD’ in the following characteristics:

- 1. Under high light conditions, leaves of plants of the new Weigela are not as heavily tinged as leaves of plants of ‘SMWFDFPD’.
- 2. Plants of the new Weigela flower more remontantly than plants of ‘SMWFDFPD’.

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 flowering plant of ‘SMNWFG’ grown in an outdoor nursery.

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

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and the following description were grown during the spring 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 three 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.
