Claims
The invention claimed is:
1. A new and distinct cultivar of Dianthus plant named `WP08 NIK03`
as described and illustrated herein.
Description
Genus: Dianthus.
Species: .times.hybrida.
Denomination: `WP08 NIK03`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
hardy garden pink or carnation that is grown for use as a flowering
plant for pots and containers and for planting in the garden or
landscape. The new cultivar is known botanically as
Dianthus.times.hybrida and will be referred to hereinafter by the
cultivar name `WP08 NIK03`.
`WP08 NIK03` is a complex hybrid plant that is the product of a
breeding program started by the inventor in 1985. The breeding
program is conducted in a cultivated area of Houndspool, Dawlish,
Devon, United Kingdom. The inventor selected `WP08 NIK03` in 2003
for its extremely compact habit and its early-blooming large fully
double magenta-colored flowers.
`WP08 NIK03` resulted from the controlled pollination between two
unreleased and unpatented varieties, namely Dianthus code number
ASH21 as female parent plant and Dianthus code number 99.24 as male
parent plant.
`WP08 NIK03` is distinguishable from the female parent as follows:
The female parent has semi-double carmine flowers.
`WP08 NIK03` is distinguishable from the male parent as follows:
The male parent is taller in height and bears only single flowers
which are colored pink.
The variety of Dianthus which is considered by the inventor to most
closely resemble `WP08 NIK03` is the inventor's variety Dianthus
`DEVON PP11` (U.S. Plant Pat. No. 14,919). `WP08 NIK03` is
distinguishable from `DEVON PP11` as follows: `WP08 NIK03` is
shorter than `DEVON PP11` whose flowers are semi-double and
lavender colored.
Asexual reproduction of the new cultivar was first accomplished by
the inventor in 2003 in a cultivated area of Houndspool, United
Kingdom. The method of asexual propagation used was vegetative
cuttings. Since that time the characteristics of the new cultivar
have been determined stable and are reproduced true to type in
successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent
the characteristics of the new Dianthus cultivar `WP08 NIK03`.
These traits in combination distinguish this cultivar from all
other commercial varieties known to the inventor. `WP08 NIK03` has
not been tested under all possible conditions and phenotypic
differences may be observed with variations in environmental,
climatic and cultural conditions, however, without any variance in
genotype. 1. Dianthus `WP08 NIK03` exhibits an extremely compact
habit. At 9 months of age, the height of the foliage mound of
Dianthus `WP08 NIK03` is 10 cm to 14 cm, and the width of the plant
is 13 cm to 15 cm. 2. Dianthus `WP08 NIK03` blooms early and
profusely from March until October. 3. Dianthus `WP08 NIK03` bears
fully double magenta colored flowers. 4. Dianthus `WP08 NIK03`
exhibits grey-green foliage. 5. Dianthus `WP08 NIK03` is perennial
and is hardy to -15.degree. C. 6. Dianthus `WP08 NIK03` is suitable
for use as a flowering plant in pots and containers.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance
of the new Dianthus variety `WP08 NIK03` showing colors as true as
it is reasonably possible to obtain in colored reproductions of
this type. Colors in the drawings may differ from the color values
cited in the detailed botanical description, which accurately
describe the actual colors of the new variety `WP08 NIK03`.
The drawing labeled as FIG. 1 depicts an entire flowering
plant.
The drawing labeled as FIG. 2 depicts a close-up view of the
flower.
All drawings were made of 9 months old plants which have been grown
in 1.5-liter containers in a cold glasshouse in Devon, United
Kingdom. No chemicals were used to treat the plants. All drawings
were made using conventional techniques and although colors may
appear different from actual colors due to light reflectance they
are as accurate as possible by conventional photography.
DETAILED BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the new cultivar `WP08
NIK03`. Data was collected in spring from 1.5-liter container
plants in spring, and grown indoors in Devon, United Kingdom. The
color determinations are in accordance with the 2007 edition of The
Royal Horticultural Society Colour Chart of The Royal Horticultural
Society, London, England, except where general color terms of
ordinary dictionary significance are used. The colors of stems,
leaves, calyx, and epicalyx have been noted on plants which retain
the characteristic waxy bloom of Dianthus. No chemicals were used
to treat the plants. Growing conditions are typical to other
Dianthus. Botanical classification: Family.--Caryophyllaceae.
Genus.--Dianthus. Species.--.times.allwoodii. Denomination.--`WP08
NIK03`. Parentage: A complex Dianthus hybrid whose immediate
parents are unreleased hybrids from the inventor's breeding
program, identified as follows: Male parent.--Selection 99.24.
