plant named ‘SMNCSBD’

Abstract

A new and distinct cultivar of Cornus plant named ‘SMNCSBD’, characterized by its compact, upright to outwardly spreading and sprawling plant habit; vigorous growth habit; medium green-colored leaves; numerous single-type flowers that are white in color; white to light yellow green-colored fruits; and good garden performance.

Description

Botanical classification: Cornus stolonifera.

Cultivar designation: ‘SMNCSBD’.

BACKGROUND OF THE INVENTION

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

The new Cornus plant originated from an open-pollination in 2011 of Cornus stolonifera ‘Flaviramea’, not patented, as the female, or seed parent with an unknown selection of Cornus stolonifera, as the male, or pollen, parent. The new Cornus plant was discovered and selected by the Inventor in 2016 as a single plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.

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

SUMMARY OF THE INVENTION

Plants of the new Cornus 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 ‘SMNCSBD’. These characteristics in combination distinguish ‘SMNCSBD’ as a new and distinct Cornus plant:

• • 1. Compact, upright to outwardly spreading and sprawling plant habit.
  • 2. Vigorous growth habit.
  • 3. Medium green-colored leaves.
  • 4. Numerous single-type flowers that are white in color.
  • 5. White to light yellow green-colored fruits.
  • 6. Good garden performance.

Plants of the new Cornus differ primarily from plants of the female parent, ‘Flaviramea’, in growth habit as plants of the new Cornus are more compact than plants of ‘Flaviramea’.

Plants of the new Cornus can be compared to plants of Cornus baileyii ‘Farrow’, disclosed in U.S. Plant Pat. No. 18,523. In side-by-side comparisons, plants of the new Cornus differ primarily from plants of ‘Farrow’ in the following characteristics:

• • 1. Plants of the new Cornus are more vigorous than plants of ‘Farrow’.
  • 2. Plants of the new Cornus have yellow green-colored stems whereas plants of ‘Farrow’ have red-colored stems.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet (FIG. 1 of 3) is a side perspective view of a typical plant grown in a container.

The photograph on the second sheet (FIG. 2 of 3) is a close-up view of typical flowers of a plant of ‘SMNCSBD’. The photograph on the third sheet (FIG. 3 of 3) is a close-up view of typical fruits of a plant of ‘SMNCSBD’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and the following observations, measurements and values describe plants grown during the summer in five-gallon containers in a polyethylene-covered greenhouse in Grand Haven, Mich. and under cultural practices typical of commercial Cornus production. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from ranged from 5° C. to 10° C. Plants were two years old when the photographs and description was 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.
