Description

[0001] Botanical designation: Diervilla x splendens.

[0002] Cultivar denomination: ‘SMNDSA’.BACKGROUND OF THE INVENTION

[0003] The present invention relates to a new and distinct cultivar of Diervilla plant, botanically known as Diervilla x splendens, commonly referred to as a hybrid Bush Honeysuckle and hereinafter referred to by the cultivar name ‘SMNDSA’.

[0004] The new Diervilla is a product of a planned breeding program conducted by the Inventor in Grand Haven, Michigan. The objective of the breeding program was to develop new compact and freely branching Diervilla plants with unique leaf shape and color.

[0005] The new Diervilla plant originated from an open-pollination during the summer of 2020 in Grand Haven, Michigan of Diervilla x splendens ‘Beauregard’, not patented, as the female, or seed, parent with an unknown proprietary selection of Diervilla x splendens as the male, or pollen, parent. The new Diervilla plant was discovered and selected by the Inventor during the summer of 2022 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Grand Haven, Michigan.

[0006] Asexual reproduction of the new Diervilla plant by softwood stem cuttings in a controlled greenhouse environment in Grand Haven, Michigan since the summer of 2022 has shown that the unique features of this new Diervilla plant are stable and reproduced true to type in successive generations of asexual reproduction.SUMMARY OF THE INVENTION

[0007] Plants of the new Diervilla 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.

[0008] The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SMNDSA’. These characteristics in combination distinguish ‘SMNDSA’ as a new and distinct Diervilla plant:

[0009] 1. Compact, upright to outwardly spreading and uniformly mounding plant habit.

[0010] 2. Vigorous growth habit and rapid growth rate.

[0011] 3. Freely branching habit; dense and bushy appearance.

[0012] 4. Dark green-colored leaves.

[0013] 5. Numerous greenish yellow-colored flowers that produce dark red-colored fruits.

[0014] 6. Good garden performance.

[0015] Plants of the new Diervilla can be compared to plants of the female parent, ‘Beauregard’. In side-by-side comparisons, plants of the new Diervilla differ primarily from plants of ‘Beauregard’ in the following characteristics:

[0016] 1. Plants of the new Diervilla are more freely and uniformly branching and denser than plants of ‘Beauregard’.

[0017] 2. Leaves of the new Diervilla are flatter than and not as concave as leaves of plants of ‘Beauregard’.

[0018] 3. Plants of the new Diervilla produce more fruits than plants of ‘Beauregard’.

[0019] Plants of the new Diervilla can be compared to plants of Diervilla sessifolia ‘Butterfly’, not patented. In side-by-side comparisons, plants of the new Diervilla differ primarily from plants of ‘Butterfly’ in the following characteristics:

[0020] 1. Plants of the new Diervilla are more freely and uniformly branching and denser than plants of ‘Butterfly’.

[0021] 2. Plants of the new Diervilla produce more fruits than plants of ‘Butterfly’.BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0022] The accompanying colored photographs illustrate the overall appearance of the new Diervilla 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 Diervilla plant.
