Abstract

A new cultivar of Dianthus plant named ‘WP10 XAV04’ which is characterized by a compact mounding habit, silver-gray foliage, fragrant fully double pink flowers with ruffled petal edges. In combination, these characteristics set ‘WP10 XAV04’ apart from all other existing varieties of Dianthus known to the inventor.

Description

Genus: DIANTHUS.
Species: ×hybrida.
Denomination: ‘WP10 XAV04’.
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 and landscape. The new cultivar is known botanically as Dianthus×hybrida and will be referred to hereinafter by the cultivar name ‘WP10 XAV04’.
‘WP10 XAV04’ 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 XAV04’ in 2004 for its fragrant pink fully double flowers, ruffled petal edges and silver-gray foliage.
‘WP10 XAV04’ resulted from the controlled cross pollination between two earlier selections of Dianthus from the inventor's breeding program, namely Dianthus ‘Devon Flavia’ (U.S. Plant Pat. No. 15,903) as female parent and Selection ‘FLA 02.13’ (unpatented and unreleased) as male parent.
‘WP10 XAV04’ is distinguishable from the female parent as follows: Whereas the flower of ‘WP10 XAV04’ is pink, fully double with ruffled petal edges, the flower of ‘Devon Flavia’ is lighter pink with a rose eye, semi-double with more fimbriated petals. In addition the foliage of the ‘Devon Flavia’ is blue-green in color, while the foliage of ‘WP10 XAV04’ is silver-gray in color.
‘WP10 XAV04’ is distinguishable from the male parent as follows: Whereas ‘WP10 XAV04’ has a compact mounding habit, the habit of the male parent is considerably taller and looser.
The variety of Dianthus which is considered by the inventor to most closely resemble ‘WP10 XAV04’ is the inventor's variety Dianthus ‘WP08 NIK03’ (U.S. Plant Pat. No. 21,418). The flowers of ‘WP08 NIK03’ are similar in size and shape but are magenta in color rather than the mid pink color of ‘WP10 XAV04’. The foliage of ‘WP08 NIK03’ is gray-green in color, while the foliage of ‘WP10 XAV04’ is silver-gray. In addition, at nine months of age, the height of a plant of ‘WP08 NIK03’ is approximately half of the height of a plant of ‘WP10 XAV04’.
Asexual reproduction of ‘WP10 XAV04’ 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. The inventor has determined that ‘WP10 XAV04’ is stable and reproduces true to type in successive generations of asexual propagation.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new Dianthus cultivar ‘WP10 XAV04’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘WP10 XAV04’ 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 XAV04’ exhibits a compact mounding habit.
    • 2. The flowers of Dianthus ‘WP10 XAV04’ are fully double.
    • 3. The flowers of Dianthus ‘WP10 XAV04’ are pink in color.
    • 4. The edges of the petals of Dianthus ‘WP10 XAV04’ are ruffled.
    • 5. Dianthus ‘WP10 XAV04’ blooms from May through October.
    • 6. Dianthus ‘WP10 XAV04’ exhibits silver-gray foliage.
    • 7. At nine months of age, the height of the foliage mound of Dianthus ‘WP10 XAV04’ is 24 cm to 28 cm, and the width is 10 cm to 12 cm.
    • 8. Dianthus ‘WP10 XAV04’ is perennial and is hardy at least to −15° C.
    • 9. Dianthus ‘WP10 XAV04’ 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 XAV04’ 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 XAV04’.
The drawing labeled as FIG. 1 depicts an entire flowering plant of ‘WP10 XAV04’.
The drawing labeled as FIG. 2 depicts a close-up view of the flower of ‘WP10 XAV04’.
All drawings were made from 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 XAV04’. Data was collected in spring from 1.5-litre container plants in spring, and grown indoors in a frost-protected greenhouse in Devon, United Kingdom. The color determinations are in accordance with the 2002 edition of The 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.
