Description

Botanical designation: Dianthus superbus.
Cultivar denomination: ‘HOLKAHORISCARLET’.
CROSS-REFERENCED TO CLOSELY-RELATED APPLICATIONS
Applicant: Kazuyuki Shishido
Title: Dianthus Plant Named ‘Holkahoripink’
Plant patent application Ser. No. 14/999,641
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Dianthus plant, botanically known as Dianthus superbus, grown commercially as a container and garden plant and hereinafter referred to by the name ‘Holkahoriscarlet’.
The new Dianthus plant is a product of a planned breeding program conducted by the Inventor in Yokoshibahikari, Sanbu, Chiba, Japan. The objective of the breeding program is to create new container Dianthus plants with numerous attractive flowers.
The new Dianthus is a naturally-occurring whole plant mutation of Dianthus superbus ‘Holkahori’, not patented. The new Dianthus plant was discovered and selected by the Inventor as a single flowering plant from a population of plants of ‘Holkahori’ in a controlled greenhouse environment in Yokoshibahikari, Sanbu, Chiba, Japan on Aug. 19, 2013.
Asexual reproduction of the new Dianthus plant by terminal cuttings propagated in a controlled greenhouse environment in Yokoshibahikari, Sanbu, Chiba, Japan since November, 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 ‘Holkahoriscarlet’. These characteristics in combination distinguish ‘Holkahoriscarlet’ as a new and distinct Dianthus plant:
    • 1. Compact, uniformly mounding and upright to broadly spreading plant habit.
    • 2. Relatively small leaves.
    • 3. Freely flowering habit.
    • 4. Intense scarlet-colored single flowers.
    • 5. Good container and garden performance.
Plants of the new Dianthus differ primarily from plants of the mutation parent, ‘Holkahori’, in flower color as plants of ‘Holkahori’ have dark pink-colored flowers.
Plants of the new Dianthus can be compared to Dianthus superbus ‘Holkahoripink’, disclosed in a U.S. Plant patent application Ser. No. 14/999,641. Plants of the new Dianthus differ primarily from plants of ‘Holkahoripink’, in flower color as plants of ‘Holkahoripink’ have pink-colored flowers.
Plants of the new Dianthus can also be compared to plants of Dianthus caryophyllus ‘Hilbeakate’, disclosed in U.S. Plant Pat. No. 28,023. In side-by-side comparisons, plants of the new Dianthus differ primarily from plants of ‘Hilbeakate’ in the following characteristics:
    • 1. Plants of the new Dianthus flower earlier than plants of ‘Hilbeakate’.
    • 2. Plants of the new Dianthus have slightly larger flowers than plants of ‘Hilbeakate’.
    • 3. Plants of the new Dianthus and ‘Hilbeakate’ differ in flower color as plants of ‘Hilbeakate’ have dark pink-colored flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph illustrates 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 photograph 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 comprises a side perspective view of a typical flowering plant of ‘Holkahoriscarlet’ grown in a container.
 DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photograph and following observations and measurements were grown during the late winter and early spring in 10.5-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial container Dianthus production.
