Claims
It is claimed:
1. A new and distinct Dahlia plant named `BKDAMPE` as illustrated
and described.
Description
Botanical designation: Dahlia hybrida.
Cultivar denomination: `BKDAMPE`.
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 `BKDAMPE`.
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 sturdy container
Dahlia plants that have a freely basal branching habit, and large
inflorescences with attractive ray floret coloration.
The new Dahlia plant originated from an open-pollination in March,
2010 in Maasdijk, The Netherlands of a proprietary selection of
Dahlia hybrida identified as code number 4001907, 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 greenhouse environment in Maasdijk, The Netherlands in
October, 2010.
Asexual reproduction of the new Dahlia plant by terminal cuttings
in a controlled greenhouse environment in Maasdijk, The Netherlands
since January, 2011 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
combinations of 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 `BKDAMPE`. These
characteristics in combination distinguish `BKDAMPE` as a new and
distinct Dahlia plant: 1. Broadly upright plant habit. 2. Freely
basal branching habit; dense and bushy growth habit. 3.
Medium-sized dark green-colored leaves. 4. Large semi-double
inflorescences with red purple-colored ray florets that are dark
red towards the base.
Plants of the new Dahlia differ primarily from plants of the female
parent selection in the following characteristics: 1. Plants of the
new Dahlia have darker green-colored leaves than plants of the
female parent selection. 2. Plants of the new Dahlia and the female
parent selection differ in ray floret color as plants of the female
parent selection have pink-colored ray florets. 3. Plants of the
new Dahlia and the female parent selection differ in inflorescence
form as plants of the female parent selection have decorative
inflorescences.
Plants of the new Dahlia can be compared to plants of Dahlia
hybrida `Dreamy Nights`, not patented. In side-by-side comparisons,
plants of the new Dahlia differ from plants of `Dreamy Nights` in
the following characteristics: 1. Plants of the new Dahlia have
glossier leaves than plants of `Dreamy Nights`. 2. Inflorescences
of plants of the new Dahlia have more ray florets than
inflorescences of plants of `Dreamy Nights`.
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 `BKDAMPE` grown in a container.
The photograph on the second sheet is a close-up view of a typical
inflorescence of `BKDAMPE`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and the following observations and
measurements describe plants grown during the winter in 12-cm
containers in a glass-covered greenhouse in Maasdijk, The
Netherlands and under cultural practices typical of commercial
Dahlia production. During the production of the plants, day and
night temperatures ranged from 17.degree. C. to 19.degree. C.
Plants were pinched one time and were eleven weeks old when the
photographs and description were taken. To induce inflorescence
initiation and development, plants were grown under short
nyctoperiod (long day) conditions. 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. Botanical classification: Dahlia
hybrida `BKDAMPE`. Parentage: Female, or seed, parent.--Proprietary
