Abstract

A new cultivar of Dianthus plant named ‘Devon Octavia’ that is characterized by compact mounding habit, medium-green foliage and pink and red flowers that bloom from April to October. In combination these traits set ‘Devon Octavia’ apart from all other existing varieties of Dianthus known to the inventor.

Description

Genus: Dianthus.
Species: xhybrida.
Denomination: ‘Devon Octavia’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of carnation that is grown for use as an ornamental container plant. The new cultivar is known botanically as Dianthus xhybrida and will be referred to hereinafter by the cultivar name ‘Devon Octavia’.
‘Devon Octavia’ is a hybrid plant that is the product of a breeding program started by the inventor in 1980. The breeding program is not federally funded and is on going, conducted in 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.
‘Devon Octavia’ was selected in 2000, by the inventor, from a large group of open pollinated seedlings. The exact parents are unknown. The female parent plant is presumed to be an unidentified cultivar of Dianthus and the male parent is presumed to be an unidentified cultivar of Dianthus. There are no close comparison plants known to the inventor.
Asexual reproduction of the new cultivar ‘Devon Octavia’ was first accomplished by the inventor in 2000 in a cultivated area of Houndspool, United Kingdom. The method of sexual propagation used was vegetative 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 Octavia’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘Devon Octavia’ 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 variation in genotype.
1. Dianthus ‘Devon Octavia’ exhibits a compact mounding growth habit.
2. Dianthus ‘Devon Octavia’ exhibits pink and red flowers.
3. Dianthus ‘Devon Octavia’ exhibits medium-green foliage.
4. Dianthus ‘Devon Octavia’ is 25-30 cm. in height and 15-20 cm in width.
5. Dianthus ‘Devon Octavia’ is an evergreen perennial herb.
6. Dianthus ‘Devon Octavia’ blooms from April to October.
7. Dianthus ‘Devon Octavia’ 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 Octavia’ 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 Octavia’.
The drawing on sheet 1 illustrates a 4-month-old plant in a 1.0-litre container.
The drawing on sheet 2 is a close-up of a typical flowers. The plants in the drawings were grown from 3 cm-plugs in an open-sided polythene structure in Devon, United Kingdom. No chemicals were used to treat 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 Octavia’. Data was collected from plants grown in 1.5-litre containers grown under glass in Houndspool, 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.
