Abstract

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

Description

Genus: Dianthus. Species: ×hybrida.

Denomination: DEVON FLORES.

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 FLORES’.

‘DEVON FLORES’ 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 FLORES’ in 2001 for its unique pronounced compact habit accompanied by abundant bright magenta flowers that bloom from May through October.

‘DEVON FLORES’ is a dwarf carnation exhibiting pronounced compact habit, grey-green foliage, and bright magenta flowers. The colors of stems, leaves, calyx, and epicalyx are of material retaining the characteristic waxy bloom of Dianthus. ‘DEVON FLORES’ resulted from the open pollination between a number of different breeding lines, each of them a complex hybrid derived from D. gratianopolitanus, D. plumarius and others. The variety of Dianthus which is considered by the inventor to most closely resemble ‘DEVON FLORES’ is the inventor's variety Dianthus ‘Devon Winnie’ (U.S. Plant Pat. No. 14,893). ‘DEVON FLORES’ is very vigorous compared to the moderately vigorous ‘Devon Winnie’. ‘DEVON FLORES’ has a stronger perfume and is a deeper magenta than ‘Devon Winnie’.

Asexual reproduction of the new cultivar was first accomplished by the inventor in 2001 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 of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Dianthus cultivar ‘DEVON FLORES’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘DEVON FLORES’ 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.

  • 5. At maturity, the height of the foliage mound of Dianthus ‘DEVON FLORES’ is 15 cm to 20 cm. The mature width is 20 cm to 30 cm.
  • 6. Dianthus ‘DEVON FLORES’ is a perennial herb.
  • 7. Dianthus ‘DEVON FLORES’ is suitable for use as a flowering plant in pots, containers, window boxes and the garden.
  • 8. Dianthus ‘DEVON FLORES’ is hardy to minus 15° Centigrade.

BRIEF DESCRIPTION OF THE DRAWING

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

The drawing labeled as FIG. 1 depicts an entire flowering plant. The drawing was made of a plant grown in 1.5-liter container in a cold glasshouse in Devon, United Kingdom. No chemicals were used to treat the plant. The drawing was 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 FLORES’. 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 2001 edition of The Royal Horticultural Society Colour Chart 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.
