Abstract

A new cultivar of Dianthus plant named ‘WP08 ROS03’ that is characterized by upright, vase-shaped habit, semi-double flowers which are uniformly deep salmon-pink in color and which bloom profusely from April until October. In combination these traits set ‘WP08 ROS03’ apart from all other existing varieties of Dianthus known to the inventor.

Description

Genus: Dianthus.
Species: ×hybrida.
Denomination: ‘WP08 ROS03’.
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 2008/1509.
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×hybrida and will be referred to hereinafter by the cultivar name ‘WP08 ROS03’.
‘WP08 ROS03’ is a complex hybrid plant that is the product of a breeding program started by the inventor in 1985 and conducted in a cultivated area of Houndspool, Dawlish, Devon, United Kingdom. The inventor selected ‘WP08 ROS03’ in 2004 for its flowers that are deep salmon pink in color and semi-double in form.
‘WP08 ROS03’ resulted from the controlled pollination between two unreleased and unpatented varieties, namely Dianthus code number ASH20 as female parent plant and Dianthus code number 99.17 as male parent plant.
‘WP08 ROS03’ is distinguishable from the female parent as follows: The female parent has semi-double carmine flowers. The female parent is less vigorous than ‘WP08 ROS03’. The flowers of the female parent are also smaller and are pink with a darker pink eye.
‘WP08 ROS03’ is distinguishable from the male parent as follows: The male parent is much taller in height and has large single flowers which are colored carmine with a white border. In addition, the foliage of ‘WP08 ROS03’ is green whereas the color of the foliage of the male parent is gray-green.
The variety of Dianthus which is considered by the inventor to most closely resemble ‘WP08 ROS03’ is the inventor's variety Dianthus ‘Stardust’ (U.S. Plant patent application Ser. No. 12/228,983, filed on Aug. 8, 2008). ‘Stardust’ bears flowers which are double in form and pale pink in color.
Asexual reproduction of the new cultivar ‘WP08 ROS03’ was first accomplished by the inventor in 2004 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 ROS03’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘WP08 ROS03’ 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 ROS03’ exhibits an upright, vase-shaped plant habit.
    • 2. Dianthus ‘WP08 ROS03’ blooms profusely from April until October.
    • 3. Dianthus ‘WP08 ROS03’ bears semi-double flowers which are uniformly deep salmon-pink in color.
    • 4. Dianthus ‘WP08 ROS03’ exhibits green foliage.
    • 5. At maturity, the height of the foliage mound of Dianthus ‘WP08 ROS03’ is 15 cm to 20 cm; the width is 10 cm to 12 cm.
    • 6. Dianthus ‘WP08 ROS03’ is perennial and is hardy to −15° C.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new Dianthus variety ‘WP08 ROS03’ 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 ROS03’.
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 ROS03’. 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.
