Claims
What is claimed is:
1. A new and distinct cultivar of Dahlia plant named `Baldenasp`,
substantially as herein illustrated and described.
Description
Latin name of genus and species of plant claimed: Dahlia
variabilis.
Variety denomination: `Baldenasp`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Dahlia plant botanically known as Dahlia variabilis and hereinafter
referred to by the cultivar name `Baldenasp`.
The new cultivar originated in a controlled breeding program in
Hem, The Netherlands during August 2013. The objective of the
breeding program was the development of Dahlia cultivars that are
freely flowering with large inflorescences, mid-season flower
timing, and a vigorous, upright-mounded growth habit.
The new Dahlia cultivar is the result of open pollination. The
female (seed) parent of the new cultivar is the proprietary Dahlia
variabilis breeding selection coded S-138, not patented,
characterized by its semi-double type, dark pink-colored
inflorescences, medium green-colored foliage, and moderately
vigorous, upright-mounded growth habit. The male (pollen) parent of
the new cultivar is unknown. The new cultivar was discovered as a
single flowering plant within the progeny of the above stated open
pollination during July 2014 in a controlled environment in Hem,
The Netherlands.
Asexual reproduction of the new cultivar by terminal stem cuttings
since July 2014 in Hem, The Netherlands and Andijk, The Netherlands
has demonstrated that the new cultivar reproduces true-to-type with
all the characteristics, as herein described, firmly fixed and
retained through successive generations of such asexual
propagation.
SUMMARY OF THE INVENTION
The following characteristics of the new cultivar have been
repeatedly observed and can be used to distinguish `Baldenasp` as a
new and distinct cultivar of Dahlia plant: 1. Double-type, medium
red colored inflorescences; 2. Dark green-colored foliage; and 3.
Vigorous, upright-mounded growth habit.
Plants of the new cultivar differ from plants of the female parent
primarily in having medium red colored inflorescences, double-type
inflorescences, and increased growth vigor.
Of the many commercially available Dahlia cultivars, the most
similar in comparison to the new cultivar is DALAYA Vampire
`Baldenrek`, U.S. Plant Pat. No. 29,662. However, in comparison,
plants of the new cultivar differ from plants of `Baldenrek` in at
least the following characteristics: 1. Plants of the new cultivar
have lighter red colored inflorescences than plants of `Baldenrek`;
2. Plants of the new cultivar have larger diameter inflorescences
than plants of `Baldenrek`; and 3. Plants of the new cultivar more
ray florets per inflorescence than plants of `Baldenrek`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show, as nearly true as it is
reasonably possible to make the same in color illustrations of this
type, typical flower and foliage characteristics of the new
cultivar. Colors in the photographs differ slightly from the color
values cited in the detailed description, which accurately
describes the colors of `Baldenasp`. The 14-week-old plants were
grown in 6.5-inch pots for 10 weeks in a glass-covered greenhouse
in Hem, The Netherlands. Plants were given one pinch before
transplant.
FIG. 1 illustrates a side view of the overall growth and flowering
habit of `Baldenasp`.
FIG. 2 illustrates a close-up view of an individual inflorescence
of `Baldenasp`.
DETAILED BOTANICAL DESCRIPTION
The new cultivar has not been observed under all possible
environmental conditions to date. Accordingly, it is possible that
the phenotype may vary somewhat with variations in the environment,
such as temperature, light intensity, and day length, without,
however, any variance in genotype.
The chart used in the identification of colors described herein is
The RHS Colour Chart of The Royal Horticultural Society, London,
England, 2015 edition, except where general color terms of ordinary
significance are used. The color values were determined in March
2021 under natural light conditions in Boskoop, The
Netherlands.
The following descriptions and measurements describe 14-week-old
plants produced from cuttings from stock plants and grown in a
glass-covered greenhouse under conditions comparable to those used
in commercial practice. The plants were grown in Hem, The
Netherlands in 6.5-inch pots for 10 weeks utilizing a soilless
growth medium. Plants were given one pinch before transplant. Three
Daminozide treatments were applied: one at 2,500 ppm two weeks
after transplant, a second at 3,000 ppm four weeks after transplant
and a third at 3,500 ppm six weeks after transplant. Greenhouse
temperatures were maintained at an average of approximately
64.degree. F. (18.degree. C.) during the day and approximately
61.degree. F. (16.degree. C.) during the night. Supplemental
lighting was used. Measurements and numerical values represent
averages of typical plants. Botanical classification: Dahlia
