Description

Botanical designation: Dianthus caryophyllus.

Cultivar denomination: ‘HILSOIMRE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus caryophyllus, grown commercially as a cut flower plant and hereinafter referred to by the name ‘Hilsoimre’.

The new Carnation plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new cut flower Carnation plants with numerous flat flowers with a single whorl of petals.

The new Carnation plant originated from a cross-pollination made by the Inventor in De Kwakel, The Netherlands in June, 2009 of a proprietary selection of Dianthus caryophyllus identified as code number WS 03-544, not patented, as the female, or seed, parent with a proprietary selection of Dianthus caryophyllus identified as code number WS 06-549, not patented, as the male, or pollen, parent. The new Carnation plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in September, 2010.

Asexual reproduction of the new Carnation plant by terminal cuttings propagated in a controlled greenhouse environment in De Kwakel, The Netherlands since October, 2010 has shown that the unique features of this new Carnation plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Carnation 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 ‘Hilsoimre’. These characteristics in combination distinguish ‘Hilsoimre’ as a new and distinct Carnation plant:

    • 1. Upright plant habit.
    • 2. Freely flowering habit.
    • 3. Flat red purple-colored flowers with a single whorl of petals; flowers face mostly upright.
    • 4. Good postproduction longevity.

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

    • 1. Plants of the new Carnation are not as freely flowering as plants of the female parent selection.
    • 2. Flowers of plants of the new Carnation face more upright than flowers of plants of the female parent selection.
    • 3. Flower petals of plants of the new Carnation are red purple in color whereas flower petals of plants of the female parent selection are dark red in color.

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

    • 1. Plants of the new Carnation are not as freely flowering as plants of the male parent selection.
    • 2. Flower petals of plants of the new Carnation are red purple in color whereas flower petals of plants of the male parent selection are light orange in color.

Plants of the new Carnation can be compared to plants of Dianthus caryophyllus ‘Hilsogil’, not patented. In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new Carnation differed from plants of ‘Hilsogil’ in the following characteristics:

    • 1. Flowers of plants of the new Carnation faced more upright than flowers of plants of ‘Hilsogil’.
    • 2. Flower petals of plants of the new Carnation were red purple in color whereas flower petals of plants of ‘Hilsogil’ were light red in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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

The photograph comprises a side perspective view of a typical flowering stem of ‘Hilsoimre’.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the spring and early summer in ground beds in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial cut flower Carnation production. During the production of the plants, day temperatures ranged from 10° C. to 25° C. and night temperatures ranged from 8° C. to 12° C. Plants were pinched one time five weeks after planting. Plants used for the photograph and description were nine months old. 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.
