Abstract

A new and distinct cultivar of Buddleia plant named ‘SMNBDD’, characterized by its compact, upright and outwardly spreading plant habit; freely branching habit; dense and bushy appearance; leathery and durable leaves; freely flowering habit; large and dense conical inflorescences with numerous dark red purple-colored flowers; and good garden performance.

Description

Botanical designation: Buddleia hybrida.

Cultivar denomination: ‘SMNBDD’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Buddleia plant, botanically known as Buddleia hybrida and hereinafter referred to by the name ‘SMNBDD’.

The new Buddleia 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 create new Buddleia plants with strong branches and attractive plant form and flower coloration.

The new Buddleia plant originated from a cross-pollination conducted by the Inventor in July, 2015 in Grand Haven, Mich. of Buddleia hybrida ‘Lilac Chip’, disclosed in U.S. Plant Pat. No. 24,016, as the female, or seed, parent with Buddleia hybrida ‘Miss Molly’, disclosed in U.S. Plant Pat. No. 23,425, as the male, or pollen, parent. The new Buddleia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Grand Haven, Mich. during the summer of 2017.

Asexual reproduction of the new Buddleia plant by softwood stem cuttings in a controlled environment in Grand Haven, Mich. since the summer of 2017 has shown that the unique features of this new Buddleia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

• • 1. Compact, upright and outwardly spreading plant habit.
  • 2. Freely branching habit; dense and bushy appearance.
  • 3. Leathery and durable leaves.
  • 4. Freely flowering habit.
  • 5. Large and dense conical inflorescences with numerous dark red purple-colored flowers.
  • 6. Good garden performance.

Plants of the new Buddleia differ primarily from plants of the female parent, ‘Lilac Chip’, in flower color as plants of the Buddleia have dark red purple-colored flowers whereas plants of ‘Lilac Chip’ have purple pink-colored flowers. In addition, plants of the new Buddleia have longer inflorescences than plants of ‘Lilac Chip’.

Plants of the new Buddleia differ primarily from plants of the male parent, ‘Miss Molly’, in growth habit as plants of the new Buddleia are more compact than plants of ‘Miss Molly’.

Plants of the new Buddleia can also be compared to plants of Buddleia hybrida ‘Pink Micro Chip’, disclosed in U.S. Plant Pat. No. 26,547. In side-by-side comparisons, plants of the new Buddleia differ primarily from plants of ‘Pink Micro Chip’ in the following characteristics:

• • 1. Plants of the new Buddleia are larger than plants of ‘Pink Micro Chip’.
  • 2. Plants of the new Buddleia have larger flowers than plants of ‘Pink Micro Chip’.
  • 3. Plants of the new Buddleia and ‘Pink Micro Chip’ differ in flower color as plants of the new Buddleia have darker red purple-colored than plants of ‘Pink Micro Chip’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet (FIG. 1 of 2) is a top perspective view of a typical flowering plant of ‘SMNBDD’ grown in an outdoor nursery.

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

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in three-gallon containers in polyethylene-covered greenhouses in Grand Haven, Mich. and under cultural practices typical of commercial production. Plants were two years old when the photographs and description were taken. 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.
