Claims
What is claimed is:
1. A new and distinct cultivar of Dianthus plant named `DDTBW13-0`
as herein illustrated and described.
Description
Latin name of the genus and species: Dianthus hybrid.
Variety denomination: `DDTBW13-0`.
BACKGROUND OF THE INVENTION
The new cultivar is a product of a planned breeding program. The
new variety originated as the result of the crossing of the female
parent, an unpatented, proprietary Dianthus referred to as
`13-307-001`.and the pollen parent, a different unpatented
proprietary Dianthus referred to as `13-130-002`. The crossing was
made during July 2017 at a commercial greenhouse in Santa Paula,
Calif. `DDTBW13-0` was discovered and selected at a commercial
greenhouse in Santa Paula, Calif., in December of 2018.
Asexual reproduction of the new cultivar `DDTBW13-0` was first
performed in Santa Paula, Calif. at a research greenhouse by
vegetative terminal cuttings in January of 2019. `DDTBW13-0` has
since produced several generations and has shown that the unique
features of this cultivar are stable and reproduced true to
type.
SUMMARY OF THE INVENTION
The cultivar `DDTBW13-0` has not been observed under all possible
environmental conditions. The phenotype may vary somewhat with
variations in environment such as temperature, day length, 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 `DDTBW13-0`. These
characteristics in combination distinguish `DDTBW13-0` as a new and
distinct Dianthus cultivar: 1. Unique burgundy colored flowers with
a distinct white margin on the petals. 2. Early flowering. 3.
Suitability for both garden and container uses. 4. Extended bloom
time into Summer and Fall months. 5. Hardy to USDA Zone 5.
PARENTAL COMPARISON
Plants of the new cultivar `DDTBW13-0` are comparable to the seed
parent in most horticultural characteristics; however, the new
variety `DDTBW13-0` differs in the following: 1. Plants of the new
variety are more compact than plants of the seed parent.
Plants of the new cultivar `DDTBW13-0` are comparable to the pollen
parent in most horticultural characteristics; however, the new
variety `DDTBW13-0` differs in the following: 1. The new variety
produces multi-whorled flowers, the pollen parent produces single
flowers.
COMMERCIAL COMPARISON
Plants of the new cultivar `DDTBW13-0` are comparable to the
commercial Dianthus variety `DDTHP02-0`, U.S. Plant Pat. No.
28,102. The two Dianthus varieties are similar in most
horticultural characteristics; however, the new variety `DDTBW13-0`
differs in the following: 1. The new variety produces bi-color
burgundy and white flowers while this comparator has solid pink
flowers. 2. Foliage of the new variety is longer and narrower than
foliage of this comparator. 3. Plants of the new variety are on
average 2.5 cm taller than plants of this comparator.
Plants of the new cultivar `DDTBW13-0` are comparable to the
commercial Dianthus variety `DCACR08-0`, U.S. Plant Pat. No.
30,026. The two Dianthus varieties are similar in most
horticultural characteristics; however, the new variety `DDTBW13-0`
differs in the following: 1. The new variety produces bi-color
burgundy and white flowers while this comparator has solid dark
pink flowers. 2. Foliage of the new variety is brighter green than
foliage of this comparator.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color a
typical plant of `DDTBW13-0` in a greenhouse in Santa Paula, Calif.
This plant are approximately 12 weeks old, grown in a 6 inch
pot.
FIG. 2 illustrates a close-up view of the flowers.
The photographs were taken using conventional techniques and
although colors may appear different from actual colors due to
light reflectance it is as accurate as possible by conventional
photographic techniques.
