Dianthus plant named `WP08 IAN04`
Abstract
A new cultivar of Dianthus plant named `WP08 IAN04` that is
characterized by pronounced compact habit, grey-green foliage, and
flowers that are double and whose petal grounds are bright cherry
red with a pale pink margin, and which bloom from April through
October. In combination these traits set `WP08 IAN04` apart from
all other existing varieties of Dianthus known to the inventor.

Claims
The invention claimed is:
1. A new and distinct cultivar of Dianthus plant named `WP08 IAN04`
as described and illustrated herein.
Description
Genus: Dianthus.
Species: .times.hybrida.
Denomination: `WP08 IAN04`.
BACKGROUND OF THE INVENTION
This application claims the benefit of priority under 35 U.S.C.
119(f) of the application for a grant of European Community Plant
Breeders Rights which was filed for the instant plant variety on
Jun. 30, 2008, Application Number 2008/1511.
The present invention relates to a new and distinct cultivar of
hardy garden pink or carnation which 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 IAN04`.
`WP08 IAN04` 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 IAN04` in 2004
for its flowers that are double and whose petal grounds are bright
cherry red with a pale pink margin, and which bloom from April
through October.
`WP08 IAN04` resulted from the controlled pollination between two
unreleased and unpatented varieties, namely Dianthus code number
FLA 02.28 as female parent plant and Dianthus code number 99.17 as
male parent plant.
`WP08 IAN04` is distinguishable from the female parent as follows:
The female parent is smaller in height with light pink flowers.
`WP08 IAN04` is distinguishable from the male parent as follows:
The male parent is taller in height and has large single flower
whose color is carmine with white border. In addition, the buds of
`WP08 IAN04` exhibit a chocolate brown coloration.
The variety of Dianthus which is considered by the inventor to most
closely resemble `WP08 IAN04` is the inventor's variety Dianthus
`Coral Reef` (U.S. Plant Pat. No. 19,660). `WP08 IAN04` is
distinguishable from this variety as follows: `Coral Reef` bears
lighter salmon-pink flowers with a pale pink edge.
Asexual reproduction of the new cultivar was first accomplished by
the inventor in 2000 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 IAN04`.
These traits in combination distinguish this cultivar from all
other commercial varieties known to the inventor. `WP08 IAN04` 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 IAN04` exhibits a compact habit. 2.
Dianthus `WP08 IAN04` blooms profusely from April until October. 3.
Dianthus `WP08 IAN04` exhibits double flowers that are bright
cherry red with a pale pink edge. 4. Dianthus `WP08 IAN04` exhibits
grey-green foliage. 5. After nine months of growth, the height of
the foliage mound of Dianthus `WP08 IAN04` is 30 cm to 35 cm; the
width is 14 cm to 16 cm. 6. Dianthus `WP08 IAN04` is perennial and
is hardy to -15.degree. C.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance
of the new Dianthus variety `WP08 IAN04` 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 IAN04`.
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
IAN04`. Data was collected in spring from 1.5-liter container

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.
