Dianthus plant named ‘Devon Starling’

Abstract

A new cultivar of Dianthus plant named ‘Devon Starling’ that is characterized by pronounced compact habit, grey-green foliage, and vivid purple flowers. In combination these traits set ‘Devon Starling’ apart from all other existing varieties of Dianthus known to the inventor.

Description

Genus: Dianthus.

Species: ×hybrida.

Denomination: Devon Starling.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of carnation that is grown for use as a flowering plant for pots and containers. The new cultivar is known botanically as Dianthus×hybrida and will be referred to hereinafter by the cultivar name ‘Devon Starling’.

‘Devon Starling’ is a complex hybrid plant that is the product of a breeding program started by the inventor in 1980. The breeding program is ongoing, conducted in a cultivated area of Houndspool, Dawlish, Devon, United Kingdom. The primary focus of the breeding program is to produce new cultivars of carnations that exhibit unique growth habit. The inventor selected ‘Devon Starling’ in 2000 for its unique pronounced compact habit accompanied by abundant vivid purple flowers that bloom from May through October.

‘Devon Starling’ is a dwarf carnation exhibiting pronounced compact habit, grey-green foliage, and vivid purple flowers. The colors of stems, leaves, calyx, and epicalyx are of material retaining the characteristic waxy bloom of Dianthus. ‘Devon Starling’ resulted from the open pollination between Dianthus ‘Peace’ (unpatented) as female parent plant and an unidentified and unknown variety of Dianthus as male parent plant. Dianthus ‘Peace’ is a cultivar of unknown parentage but derived from Dianthus gratianopolitanus (species, unpatented) and other Dianthus species and hybrids.

‘Devon Starling’ is distinguishable from the female parent by pronounced compact habit and purple flowers. Dianthus gratianopolitanus, also known as the Cheddar Pink, has pink flowers on a loose open plant habit.

The varieties of Dianthus which are considered by the inventor to most closely resemble ‘Devon Starling’ are the two unpatented varieties Dianthus ‘Whatfield Magenta’ and Dianthus ‘Warden Hybrid’. When compared with these two varieties, the flowers of ‘Devon Starling’ are larger and exhibit a deeper and more saturated coloration. In addition, plants of ‘Devon Starling’ flower over a longer period than the two varieties and the plant habit of ‘Devon Starling’ is more compact and mounding.

Asexual reproduction of the new cultivar was first accomplished by the inventor in 2000 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 ‘Devon Starling’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘Devon Starling’ 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.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Dianthus variety ‘Devon Starling’ 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 ‘Devon Starling’.

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 plants grown in 1.5-liter 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.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar ‘Devon Starling’. Data was collected in spring from 1.5-liter container plants in spring, 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. No chemicals were used to treat the plants. Growing conditions are typical to other Dianthus.
