Abstract

A new cultivar of Dianthus plant named ‘WP17 PIE54’ that is characterized by a compact mounding habit, large single magenta flowers with a darker contrasting band color, blooming from May through October, with a strong, pleasant spicy fragrance, strongly glaucous blue green foliage and is suitable for use as a flowering plant in pots and containers as well as for use as a cut flower and in bouquets, is disclosed.

Description

Genus and species: Dianthus x allwoodii hort.
Variety denomination: ‘WP17 PIE54’.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct cultivar of hardy Dianthus, commonly 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 x allwoodii hort. and will be referred to hereinafter by the cultivar name ‘WP17 PIE54’.
‘WP17 PIE54’ 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. ‘WP17 PIE54’ was selected in 2009 for its large single vibrant magenta flowers, its strong, pleasant spicy fragrance, and glaucous blue-green foliage.
‘WP17 PIE54’ arose and was selected as a seedling which resulted from the controlled pollination of two of the inventor's prior selections of Dianthus. The male parent is Dianthus code name ‘GI52’ (unpatented and unreleased) and the female parent is Dianthus code name ‘Tricia’ (unpatented and unreleased). The male parent and female parent had both been grown within the inventor's stock of breeding lines.
Asexual reproduction of ‘WP17 PIE54’ was first accomplished in 2009 in a cultivated area of Houndspool, United Kingdom using the propagation method of shoot cuttings. ‘WP17 PIE54’ has been determined to be stable and reproduces true to type in successive generations of asexual propagation.
SUMMARY
The following traits have been repeatedly observed and represent the characteristics of the new Dianthus cultivar ‘WP17 PIE54’. ‘WP17 PIE54’ 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.

    • 4. ‘WP17 PIE54’ blooms from May through October.
    • 5. The flowers of ‘WP17 PIE54’ exhibit a strong, pleasant spicy fragrance.
    • 6. ‘WP17 PIE54’ exhibits strongly glaucous blue-green foliage.
    • 7. At maturity, the height of the foliage mound of ‘WP17 PIE54’ is 45 cm, and the width is 30 cm to 35 cm.
    • 8. ‘WP17 PIE54’ is perennial and is hardy at least to minus 15° Centigrade.
    • 9. ‘WP17 PIE54’ is suitable for use as a flowering plant in pots and containers, and for use as a cut flower and in bouquets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying color photographs illustrate the overall appearance of the new Dianthus variety ‘WP17 PIE54’ 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 ‘WP17 PIE54’.
FIG. 1 depicts an entire flowering plant of ‘WP17 PIE54’.
FIG. 2 depicts a close-up view of the flower of ‘WP17 PIE54’.
Photographs were taken from a 9 months old plant which was growing in a glasshouse in a 3-liter container at the Inventor's nursery in Dawlish, 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.
BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the new cultivar ‘WP17 PIE54’. Data was collected from plants grown in 3-liter containers under an unheated glasshouse in Houndspool, Dawlish, United Kingdom.

COMPARISON WITH PARENTAL LINE AND KNOWN VARIETY
‘WP17 PIE54’ is distinguishable from the male parent as follows. Whereas the flower color and color combination of ‘GI52’ is similar to ‘WP17 PIE54’, the vegetative habit of the two varieties is very different. ‘GI52’ is much more vigorous than ‘WP17 PIE54’ and exhibits a looser habit and longer flower stems.
‘WP17 PIE54’ is distinguishable from the female parent as follows. Whereas the flower stem length and compact habit of ‘Tricia’ is similar to ‘WP17 PIE54’, the flower color of the two varieties is different. ‘Tricia’ has pale pink flowers with a darker eye.
The variety of Dianthus which the inventor considers to most closely resemble ‘WP17 PIE54’ is Dianthus Plant Named ‘WP15 PIE45’ (U.S. Plant patent application Ser. No. 15/731,061). In comparison with ‘WP15 PIE045’, ‘WP17 PIE54’ bears more flowers along each flowering stem. Whereas the flowers of ‘WP15 PIE45’ are predominantly pink-peach in color, the flowers of ‘WP17 PIE54’ are predominantly magenta in color.
