plant named ‘Bkdapdp’

Abstract

A new and distinct cultivar of Dahlia plant named ‘Bkdapdp’, characterized by its compact, upright and mounding plant habit; freely basal branching; dense and bushy growth habit; dark green-colored leaves; early and freely flowering habit; double inflorescences with dark pink-colored ray florets; and good garden performance.

Description

Botanical designation: Dahlia hybrida.

Cultivar denomination: ‘BKDAPDP’.

BACKGROUND OF THE INVENTION

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

The new Dahlia plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program is to create new container Dahlia plants that have a freely branching habit, attractive ray floret coloration, long flowering period and good garden performance.

The new Dahlia plant originated from an open-pollination in June, 2008 in Maasdijk, The Netherlands of a proprietary selection of Dahlia hybrida identified as code number 4001198, not patented, as the female, or seed, parent with an unknown selection of Dahlia hybrida as the male, or pollen, parent. The new Dahlia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Maasdijk, The Netherlands in August, 2009.

Asexual reproduction of the new Dahlia plant by cuttings in a controlled environment in Maasdijk, The Netherlands since November, 2009 has shown that the unique features of this new Dahlia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Dahlia have not been observed under all possible environmental conditions and cultural conditions. 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 ‘Bkdapdp’. These characteristics in combination distinguish ‘Bkdapdp’ as a new and distinct Dahlia plant:

• • 1. Compact, upright and mounding plant habit.
  • 2. Freely basal branching; dense and bushy growth habit.
  • 3. Dark green-colored leaves.
  • 4. Early and freely flowering habit.
  • 5. Double inflorescences with dark pink-colored ray florets.
  • 6. Good garden performance.

Compared to plants of the female parent selection, plants of the new Dahlia differ primarily in the following characteristics:

• • 1. Plants of the new Dahlia are smaller than plants of the female parent selection.
  • 2. Plants of the new Dahlia have smaller flowers than plants of the female parent selection.
  • 3. Plants of the new Dahlia and the female parent selection differ in ray floret color as plants of the female parent selection have white-colored ray florets.

Plants of the new Dahlia can be compared to plants of Dahlia ‘Micronetta Purple Pink’, not patented. In side-by-side comparisons conducted in Maasdijk, The Netherlands, plants of the new Dahlia differed from plants of ‘Micronetta Purple Pink’ in the following characteristics:

• • 1. Plants of the new Dahlia were more freely branching than plants of ‘Micronetta Purple Pink’.
  • 2. Plants of the new Dahlia had shorter peduncles than plants of ‘Micronetta Purple Pink’.
  • 3. Plants of the new Dahlia and ‘Micronetta Purple Pink’ differed slightly in ray floret color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Dahlia 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 Dahlia plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Bkdapdp’ grown in a container.

The photograph on the second sheet is a close-up view of typical inflorescences and leaves of ‘Bkdapdp’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and the following observations and measurements describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Maasdijk, The Netherlands and under environmental conditions and cultural practices which approximate those generally used in commercial container Dahlia production. During the production of the plants, day temperatures ranged from 17° C. to 19° C. and night temperatures ranged from 15° C. to 17° C. Plants were pinched one time and were 65 days old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
