Description

Botanical designation: Dianthus hybrida.

Cultivar denomination: ‘KonD1044K2’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dianthus plant, botanically known as Dianthus hybrida, grown commercially as a container and garden plant and hereinafter referred to by the name ‘KonD1044K2’.

The new Dianthus plant is a product of a planned breeding program conducted by the Inventor in Westerbrok, The Netherlands. The objective of the breeding program is to create new hardy Dianthus plants with remontant flowering habit with good container and garden performance.

The new Dianthus plant originated from a cross-pollination in May, 2009 of a proprietary selection of Dianthus hybrida identified as code number E1408, not patented, as the female, or seed, parent with a proprietary selection of Dianthus hybrida identified as code number D900, not patented, as the male, or pollen, plant. The new Dianthus plant was discovered and selected by the Inventor in July, 2010 as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Westerbrok, The Netherlands.

Asexual reproduction of the new Dianthus plant by vegetive terminal cuttings propagated in a controlled greenhouse environment in Chicago, Ill. since September, 2010 has shown that the unique features of this new Dianthus plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Dianthus have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KonD1044K2’. These characteristics in combination distinguish ‘KonD1044K2’ as a new and distinct Dianthus plant:

    • 1. Uniformly mounding and upright to broadly spreading plant habit; dense and bushy appearance.
    • 2. Relatively long dark green-colored leaves.
    • 3. Freely and remontant flowering habit.
    • 4. Relatively large red pink-colored single flowers with purple-colored central ring and white-colored throat.
    • 5. No vernalization requirement for flowering.
    • 6. Good container and garden performance.

Plants of the new Dianthus differ primarily from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Dianthus are more compact than and not as vigorous as plants of the female parent selection.
    • 2. Plants of the new Dianthus have larger flowers than plants of the female parent selection.

Plants of the new Dianthus differ primarily from plants of the male parent selection in the following characteristics:

    • 1. Plants of the new Dianthus have larger flowers than plants of the male parent selection.
    • 2. Plants of the new Dianthus and the male parent selection differ in flower color as plants of the male parent selection have light red purple-colored flowers.

Plants of the new Dianthus can also be compared to plants of Dianthus caryophyllus ‘Kahori’, not patented. In side-by-side comparisons, plants of the new Dianthus differ primarily from plants of ‘Kahori’ in the following characteristics:

    • 1. Plants of the new Dianthus are more vigorous than plants of ‘Kahori’.
    • 2. Plants of the new Dianthus have larger flowers than plants of ‘Kahori’.
    • 3. Plants of the new Dianthus rebloom more consistently than plants of ‘Kahori’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Dianthus plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Dianthus plant.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘KonD1044K2’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘KonD1044K2’.

 DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the winter and spring in one-gallon containers in a glass-covered greenhouse in Elburn, Ill. and under cultural practices typical of commercial container Dianthus production. During the final production phase of the plants, day temperatures ranged from 18° C. to 21° C. and night temperatures ranged from 13° C. to 16° C. Plants were pinched two times during the propagation phase and were eight months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
