Abstract

A new cultivar of Dianthus plant named ‘WP10 HEL01’ which is characterized by compact mounding plant habit, silver-gray foliage and fragrant semi double flowers which are pure white in color with a deep cherry eye. In combination, these characteristics set ‘WP10 HEL01’ apart from all other existing varieties of Dianthus known to the inventor.

Description

Genus: DIANTHUS.
Species: ×hybrida.
Denomination: ‘WP10 HEL01’.
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. 25, 2010, Application Number 2010/1268.
The present invention relates to a new and distinct cultivar of hardy Dianthus, also known as garden pink, which is grown for use as a flowering plant for pots and containers and for planting in the garden and landscape. The new cultivar is known botanically as Dianthus×hybrida and will be referred to hereinafter by the cultivar name ‘WP10 HEL01’.
‘WP10 HEL01’ is a complex hybrid plant that is the product of a long term breeding program conducted by the inventor in a cultivated area of Houndspool, Dawlish, Devon, United Kingdom. The inventor selected ‘WP10 HEL01’ in 2001 for its fragrant flowers which are semi-double and pure white in color with a deep cherry red eye, and also for its contrasting foliage. The foliage of ‘WP10 HEL01’ is markedly silver-gray in color.
‘WP10 HEL01’ was selected from seedlings raised by the inventor using seed which resulted from the open pollination of Dianthus ‘Mendlesham Minx’ (unpatented) as female parent plant. The inventor had deliberately exposed ‘Mendlesham Minx’ to open pollination by placing ‘Mendlesham Minx’ within a collection of the inventor's unreleased and unpatented seedlings during their flowering period.
‘WP10 HEL01’ is distinguishable from the female parent as follows: The habit of the female parent is more spreading, whereas ‘WP10 HEL01’ has a compact mounding habit. The flowers of the female parent are single, maroon in color with a white edge and flecks of white overall, whereas the flowers of ‘WP10 HEL01’ are semi-double and white in color with a deep cherry eye. The foliage of the female parent is blue-green as is typical of the genus Dianthus, whereas the foliage of ‘WP10 HEL01’ is silver-gray in color.
‘WP10 HEL01’ cannot be described in comparison with the unknown male parent.
The variety of Dianthus which is considered by the inventor to most closely resemble ‘WP10 HEL01’ is Dianthus ‘BRILLIANT STAR’ (U.S. Plant Pat. No. 13,025). ‘BRILLIANT STAR’ is distinguishable from ‘WP10 HEL01’ as follows: Mature plants of ‘BRILLIANT STAR’ are approximately 2.5 cm shorter in height than plants of ‘WP10 HEL01’. ‘BRILLIANT STAR’ has a more compact habit with flowers borne on shorter stems. The foliage of ‘BRILLIANT STAR’ is blue green in color. In addition, the flowers of ‘WP10 HEL01’ are larger and more double compared to the flowers of “BRILLIANT STAR’.
Asexual reproduction of ‘WP10 HEL01’ was first accomplished by the inventor in 2001 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 ‘WP10 HEL01’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘WP10 HEL01’ 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 ‘WP10 HEL01’ exhibits a compact mounding habit.
    • 2. The flowers of Dianthus ‘WP10 HEL01’ are semi double.
    • 3. The flowers of Dianthus ‘WP10 HEL01’ are pure white in color with a deep cherry eye.
    • 4. Dianthus ‘WP10 HEL01’ blooms from April through October.
    • 5. Dianthus ‘WP10 HEL01’ exhibits glaucous silver-gray foliage.
    • 6. At eight months of age, the height of the foliage mound of Dianthus ‘WP10 HEL01’ is 22 cm to 28 cm, and the width is 15 cm to 20 cm.
    • 7. Dianthus ‘WP10 HEL01’ is perennial and is hardy to −15° C.
8. Dianthus ‘WP10 HEL01’ 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 ‘WP10 HEL01’ 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 ‘WP10 HEL01’.
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-litre 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 ‘WP10 HEL01’. Data was collected in spring from 1.5-litre container plants, and grown indoors in Devon, United Kingdom. The color determinations are in accordance with the 2002 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.
