Description

Botanical designation: Dianthus hybrida.

Cultivar denomination: ‘KonD1335K1’.

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 ‘KonD1335K1’.

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, 2012 of a proprietary selection of Dianthus hybrida identified as code number D11229, not patented, as the female, or seed, parent with a proprietary selection of Dianthus hybrida identified as code number D934, not patented, as the male, or pollen, plant. The new Dianthus plant was discovered and selected by the Inventor in July, 2013 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, 2013 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 ‘KonD1335K1’. These characteristics in combination distinguish ‘KonD1335K1’ as a new and distinct Dianthus plant:

    • 1. Uniformly mounding and upright to broadly spreading plant habit; dense and bushy appearance.
    • 2. Freely and remontant flowering habit from early spring until the autumn.
    • 3. Dark red-colored single flowers.
    • 4. No vernalization requirement for flowering.
    • 5. 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 vigorous than 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 are not as vigorous as plants of the male parent selection.
    • 2. Plants of the new Dianthus and the male parent selection differ in flower form as plants of the new Dianthus have single flowers whereas plants of the male parent selection have semi-double flowers.

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

    • 1. Plants of the new Dianthus have shorter flowering stems than plants of ‘Fusilier’.
    • 2. Plants of the new Dianthus have larger flowers than plants of ‘Fusilier’.
    • 3. Plants of the new Dianthus have single-type flowers whereas plants of ‘Fusilier’ have semi-double flowers.

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 (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘KonD1335K1’ grown in an outdoor nursery.

The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flowering plant of ‘KonD1335K1’.

 DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and following observations and measurements were grown during the summer in ground beds and in 2.5-quart 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 13° C. to 27° C., night temperatures ranged from 7° C. to 18° C. and light levels ranged from 5,000 to 8,000 foot-candles. Plants were 18 weeks old when the photographs were taken and 20 weeks old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
