USPP20628P2 - Dianthus plant named ‘BRIGHT EYES’ - Google Patents

Abstract

A new cultivar of Dianthus plant named ‘BRIGHT EYES’ that is characterized by compact habit, grey-green foliage, and double flowers that are predominantly white in color with deep plum-red centers. In combination these traits set ‘BRIGHT EYES’ apart from all other existing varieties of Dianthus known to the inventor.

Description

Genus: Dianthus.

Species: ×hybrida.

Denomination: ‘BRIGHT EYES’.

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 2007/1925 filed Sep. 3, 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 ‘BRIGHT EYES’.

‘BRIGHT EYES’ 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 ‘BRIGHT EYES’ in 2002 for its double flowers which are colored white with a deep plum red center.

‘BRIGHT EYES’ resulted from the controlled pollination between an unreleased and unpatented Dianthus previously raised by the inventor and known by its code name Dianthus ‘Tricia’ as female parent plant, and an unknown Dianthus as male parent plant.

‘BRIGHT EYES’ is distinguishable from the female parent whose flowers are pale pink with a dark eye. The male parent is unknown and cannot be described.

The varieties of Dianthus which are considered by the inventor to most closely resemble ‘BRIGHT EYES’ are Dianthus ‘Cranmere Pool’ (unpatented) and Dianthus ‘Lady Madonna’ (unpatented). The flowers of ‘Cranmere Pool’ are more double and are larger than the flowers of ‘BRIGHT EYES’. The margins of the flower petals of ‘Lady Madonna’ are more deeply fimbriated than the margins of the flower petals of ‘BRIGHT EYES’. ‘BRIGHT EYES’ is also a more vigorous plant than ‘Lady Madonna’.

Asexual reproduction of the new cultivar was first accomplished by the inventor in 2002 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 ‘BRIGHT EYES’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘BRIGHT EYES’ 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. ‘BRIGHT EYES’ exhibits a compact habit.
  • 2. ‘BRIGHT EYES’ blooms profusely.
  • 3. ‘BRIGHT EYES’ exhibits double flowers that are predominantly white in color with deep plum-red centers.
  • 4. ‘BRIGHT EYES’ blooms from April through October.
  • 5. ‘BRIGHT EYES’ exhibits grey-green foliage.
  • 6. At maturity, the height of the foliage mound of ‘BRIGHT EYES’ is 50 cm to 60 cm; the width is 35 cm to 40 cm.
  • 7. ‘BRIGHT EYES’ is perennial and is hardy to −15° C.
  • 8. ‘BRIGHT EYES’ 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 ‘BRIGHT EYES’ 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 ‘BRIGHT EYES’.

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-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 ‘BRIGHT EYES’. Data was collected in spring from 1.5-litre container plants in spring, which were growing in a cold (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.
