Abstract

A new cultivar of Dianthus plant named ‘STARDUST’ that is characterized by compact habit, grey-green foliage, and double flowers that are pale coral in color. In combination these traits set ‘STARDUST’ apart from all other existing varieties of Dianthus known to the inventor.

Description

Genus: Dianthus.
Species: ×hybrida.
Denomination: ‘STARDUST’.
BACKGROUND OF THE INVENTION
This application claims the benefit of priority under 35 U.S.C. 119(f) of the earlier application for European Community Plant Breeders Rights, Application Number 2007/2058 filed Sep. 19, 2007.
The present invention relates to a new and distinct cultivar of Dianthus that is grown for use as a flowering plant for pots and containers and as a hardy perennial for the garden and landscape. The new cultivar is known botanically as Dianthus×hybrida and will be referred to hereinafter by the cultivar name ‘STARDUST’.
‘STARDUST’ is a complex hybrid plant that is the product of a long term breeding program conducted in a greenhouse environment in Houndspool, Dawlish, Devon, United Kingdom. The primary focus of the breeding program is to produce new cultivars of Dianthus that exhibit unique growth habit and flower colors. The inventor selected ‘STARDUST’ in 2004 for its double flowers that are pale coral in color.
‘STARDUST’ resulted from the controlled pollination between an unreleased and unpatented Dianthus previously raised by the inventor and known by its code name Dianthus ‘SUW03.08’ as female parent plant, and an unreleased and unpatented Dianthus previously raised by the inventor and known by its code name Dianthus ‘00.16’ as male parent plant.
‘STARDUST’ is distinguishable from both of its parents by having smaller flowers and greyer, more glaucous foliage.
The variety of Dianthus which is considered by the inventor to most closely resemble ‘STARDUST’ is the inventor's variety Dianthus ‘Devon Winnie’ (U.S. Plant Pat. No. 14,893). Whereas the flowers of ‘STARDUST’ and ‘Devon Winnie’ are both double, those of ‘Devon Winnie’ are slightly smaller (ranging from 25 mm to 35 mm in diameter) and are dark pink in color.
Asexual reproduction of the new cultivar 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 ‘STARDUST’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘STARDUST’ 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. ‘STARDUST’ exhibits a compact habit.
    • 2. ‘STARDUST’ blooms profusely.
    • 3. ‘STARDUST’ exhibits double flowers that are a pale coral in color.
    • 4. ‘STARDUST’ blooms from March through October.
    • 5. ‘STARDUST’ exhibits grey-green foliage.
    • 6. At maturity, the height of the foliage mound of ‘STARDUST’ is 13 cm to 17 cm, and the width of the foliage mound is 17 cm to 20 cm.
    • 7. ‘STARDUST’ is perennial and is hardy to −15° C.
    • 8. ‘STARDUST’ 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 ‘STARDUST’ 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 ‘STARDUST’.
The drawing labeled as FIG. 1 depicts an entire flowering plant.
All drawings were made of 9 months old plants which have grown in 1.5-litre containers in a cold (unheated) 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 ‘STARDUST’. Data was collected in spring from 9 months old plants which have been grown in 1.5-litre containers in spring, and grown in an unheated glasshouse 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.
