Dianthus plant named ‘Devon Elise’

Abstract

A new cultivar of Dianthus plant named ‘Devon Elise’ that is characterized by compact mounding habit, blue-green foliage and prominently fragrant pink flowers with pronounced dentation of the petals. In combination these traits set ‘Devon Elise’ apart from all other existing varieties of Dianthus known to the inventor.

Description

Genus: Dianthus. Species: ×hybrida.

Denomination: Devon Elise.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dianthus or garden pink that is grown for use as an ornamental container plant. It is known botanically as Dianthus×hybrida and will be referred to hereinafter by the cultivar name ‘Devon Elise’.

‘Devon Elise’ is the product of a breeding program started by the inventor in 1980 in a cultivated area of Houndspool, Dawlish, Devon, United Kingdom. The primary focus of the breeding program is to produce new cultivars of garden pinks that exhibit unique characteristics of flower color and form, and which, preferably, are highly and pleasantly fragrant. In addition, new varieties are selected for being well-proportioned in respect of ratio of overall height (including flower canopy) to overall width. A desirable characteristic of traditional garden pinks is the “pinking”, meaning dentation, of the petal margins, from which the plant name “pink” is derived, rather than the predominant pink coloration to the blooms. The flowers of ‘Devon Elise’ exhibit pronounced and attractive pinking.

‘Devon Elise’ is a chance hybrid plant that was selected in 2000 as a single seedling from a large group (which the inventor designated as Family 9754) of open-pollinated seedlings which itself had resulted from open-pollination of a group of unnamed and unreleased plants of Dianthus from the inventor's large collection of Dianthus. The inventor is unable to identify either the male or the female parent, or to draw comparisons between ‘Devon Elise’ and either parent.

‘Devon Elise’ exhibits blue-green foliage, pink flowers and a compact mounding growth habit. The inventor's variety, Dianthus Plant Named ‘Devon Winnie’ (U.S. Plant Pat. No. 14,893) exhibits similar blue-green foliage and compact habit. However, when compared with ‘Devon Winnie’ the blooms of ‘Devon Elise’ are lighter in color, tending to pink, with markedly more pronounced dentation of the petal margins. In addition, the blooms of ‘Devon Elise’ are much less double in form (fewer petals in an individual bloom) than the blooms of ‘Devon Winnie’.

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 stem cuttings. Since that time the characteristics of the new cultivar have been determined stable and are reproduced true to type in successive generations by vegetative propagation.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Dianthus cultivar ‘Devon Elise’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘Devon Elise’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, without however any change in genotype.

  • 5. Dianthus ‘Devon Elise’ is 15-18 cm. in height and 8-10 cm in width in a 1-liter container after 4-6 months.
  • 6. Dianthus ‘Devon Elise’ is an evergreen perennial herb.

  • 8. Dianthus ‘Devon Elise’ is hardy to minus 15° Centigrade.

BRIEF DESCRIPTION OF THE DRAWINGS

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

The drawing labeled as FIG. 1 illustrates an entire plant of ‘Devon Elise’ in flower.

The drawing labeled as FIG. 2 illustrates is a close-up view of two typical flowers of ‘Devon Elise’.

All drawings were made of nine month old grown in 1 liter containers under a cold glasshouse in Houndspool, 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 Elise’. Data was collected from plants grown in 1-liter containers under a cold glasshouse in Houndspool, 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.
