Description

Genus and species: Dianthus×hybrida.

Variety denomination: ‘WP13 GIL05’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority under 35 U.S.C. 119 of the earlier application for European Community Plant Variety Rights, which was filed for the instant plant variety on May 10, 2013, Application Number 2013/1279.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of hardy garden pink, 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 ‘WP13 GIL05’.

‘WP13 GIL05’ is a complex hybrid plant that is the product of a long term breeding program conducted in a cultivated area of Houndspool, Dawlish, Devon, United Kingdom. ‘WP13 GIL05’ was selected in 2005 for its semi-double white flowers with deep maroon eye, fringed petal edges, moderate to strong spicy clove-like fragrance and gray-blue foliage.

‘WP13 GIL05’ arose and was selected as a seedling which resulted from the open pollination of two prior selections of Dianthus. The male parent is known as Dianthus code name ‘Renata’ (unpatented and unreleased) and the female plant was unnamed and unreleased, and not retained. The male parent and female parent had both been grown within the inventor's stock of breeding lines.

Asexual reproduction of ‘WP13 GIL05’ was first accomplished in 2005 in a cultivated area of Houndspool, United Kingdom. The method of asexual propagation used was shoot cuttings. ‘WP13 GIL05’ was determined to be stable and reproduces true to type in successive generations of asexual propagation via vegetative cuttings.

SUMMARY

The following traits have been repeatedly observed and represent the characteristics of the new Dianthus cultivar ‘WP13 GIL05’. ‘WP13 GIL05’ 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. ‘WP13 GIL05’ exhibits a compact mounding habit.
  • 2. ‘WP13 GIL05’ bears semi-double white flowers with a deep maroon eye.
  • 3. The petals of ‘WP13 GIL05’ are ruffled with distinct fimbriated apices.
  • 4. ‘WP13 GIL05’ blooms from May through September.
  • 5. The flowers of ‘WP13 GIL05’ exhibit moderate to strong spicy or clove-like fragrance.
  • 6. ‘WP13 GIL05’ exhibits glaucous blue green foliage.
  • 7. At maturity, the height of the foliage mound of ‘WP13 GIL05’ is 24 cm, and the width is 19 cm.
  • 8. ‘WP13 GIL05’ is perennial and is hardy at least to −15° C.
  • 9. ‘WP13 GIL05’ is suitable for use as a flowering plant in pots and containers, and for use as a cut flower and in bouquets.

COMPARISON WITH PARENTAL LINE AND KNOWN VARIETY

‘WP13 GIL05’ is distinguishable from the male parent as follows. Whereas the flower shape and color of ‘Renata’ is similar to ‘WP13 GIL05’, the vegetative habit of the two varieties is very different. ‘Renata’ is much less vigorous than ‘WP13 GIL05’ and exhibits shorter flower stems and a stiffer more erect habit. In addition, the foliage of ‘Renata’ exhibits shorter and wider leaves than that of ‘WP13 GIL05’.

The identity of the female parent is unknown and therefore a comparison is not possible.

The variety of Dianthus considered to most closely resemble ‘WP13 GIL05’ is the semi-double white with maroon eye flowered Dianthus ‘Brilliant Star’ (U.S. Plant Pat. No. 13,025). In comparison with ‘WP13 GIL05’, the plant of ‘Brilliant Star’ exhibits less plant vigor and a more compact habit with flowers borne on shorter stems than ‘WP13 GIL05’. In addition, the flowers of ‘WP13 GIL05’ exhibit a distinctly fimbriated petal edge in comparison to ‘Brilliant Star’ which has a less fringed edge.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Dianthus variety ‘WP13 GIL05’ showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘WP13 GIL05’.

FIG. 1 depicts an entire flowering plant of ‘WP13 GIL05’.

FIG. 2 depicts a close-up view of the flowers and buds of ‘WP13 GIL05’.

All photographs were made from one year 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 photographs 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.
