Claims
It is claimed:
1. A new and distinct Dahlia plant named `Bkdadp` as illustrated
and described.
Description
Botanical designation: Dahlia hybrida.
Cultivar denomination: `BKDADP`.
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 `Bkdadp`.
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 July,
2006 in Maasdijk, The Netherlands of a proprietary selection of
Dahlia hybrida identified as code number 2006-0102, 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 July,
2007.
Asexual reproduction of the new Dahlia plant by cuttings in a
controlled environment in Maasdijk, The Netherlands since November,
2007 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 environment 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 `Bkdadp`. These
characteristics in combination distinguish `Bkdadp` as a new and
distinct Dahlia plant: 1. Compact, upright, somewhat outwardly
spreading and mounding plant habit. 2. Dense and bushy growth
habit. 3. Early and continuous flowering habit. 4. Double
inflorescences with light red purple-colored ray florets. 5. 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 shorter than plants of the female
parent selection. 2. Plants of the new Dahlia flower earlier 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 dark pink-colored ray
florets.
Plants of the new Dahlia can be compared to plants of Dahlia
`Gallery Sisley`, disclosed in U.S. Plant Pat. No. 16,808. In
side-by-side comparisons conducted in Maasdijk, The Netherlands,
plants of the new Dahlia differed from plants of `Gallery Sisley`
in the following characteristics: 1. Leaves of plants of the new
Dahlia were darker green in color than leaves of plants of `Gallery
Sisley`. 2. Leaves of plants of the new Dahlia were more deeply
serrated than leaves of plants of `Gallery Sisley`.
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 `Bkdadp` grown in a container.
The photograph on the second sheet is a close-up view of a typical
inflorescence of `Bkdadp`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and the following observations and
measurements describe plants grown during the winter in 15-cm

ranged from 17.degree. C. to 19.degree. C. Plants were pinched one
time and were nine weeks old when the photographs and description
were taken. In the following description, color references are made

used. Botanical classification: Dahlia hybrida `Bkdadp`. Parentage:
