Description

Botanical designation: Hydrangea macrophylla X Hydrangea hybrida.
Cultivar denomination: ‘FRCK 003 S 9’.
CROSS-REFERENCED TO CLOSELY RELATED APPLICATIONS
Title: Hydrangea Plant Named ‘FRCK 003 S 123’
First Named Inventor/Applicant: Hiroyuki Mekada
Filed: Concurrently with the instant application
STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT
A Japanese Plant Breeder's Rights application for the instant plant was filed by the Assignee, Shimane Prefecture of Shimane, Japan on Jun. 22, 2020, application number 34777. Foreign priority is not claimed to this application.
The Inventors/Applicants and Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventors/Applicants and/or the Assignee. Inventors/Applicants and Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for sales prior to the filing date but less than one year prior to the effective filing date.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hydrangea plant, botanically known as Hydrangea macrophylla X Hydrangea hybrida, commercially referred to as a Mophead Hydrangea and hereinafter referred to by the name ‘FRCK 003 S 9’.
The new Hydrangea plant is a product of a planned breeding program conducted by the Inventors in Izumo-shi, Shimane, Japan. The objective of the breeding program is to create new freely-branching Hydrangea plants with compact plant habit and large inflorescences with double-type sterile flowers.
The new Hydrangea plant originated from a self-pollination made by the Inventors in June, 2010 in Izumo-shi, Shimane, Japan, of a proprietary selection of Hydrangea macrophylla X Hydrangea hybrida identified as code number FRCK-003, not patented. The new Hydrangea plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated self-pollination in a controlled greenhouse environment in Izumo-shi, Shimane, Japan in April, 2015.
Asexual reproduction of the new Hydrangea plant by vegetative tip cuttings in a controlled environment in Izumo-shi, Shimane, Japan since January, 2016 has shown that the unique features of this new Hydrangea plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Hydrangea 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 ‘FRCK 003 S 9’. These characteristics in combination distinguish ‘FRCK 003 S 9’ as a new and distinct Hydrangea plant:
    • 1. Relatively compact and uniformly mounding plant habit.
    • 2. Freely branching habit.
    • 3. Strong and sturdy stems.
    • 4. Freely flowering habit.
    • 5. Large and dense mophead inflorescences with numerous double-type sterile flowers that can be “blued”.
    • 6. Good post-production longevity.
Plants of the new Hydrangea can be compared to plants of the parent selection. Plants of the new Hydrangea differ primarily from plants of the parent selection in inflorescence and flower form. Plants of the new Hydrangea have mophead inflorescences with double-type sterile flowers whereas plants of the parent selection have lacecap inflorescences with single-type sterile flowers.
Plants of the new Hydrangea can be compared to plants of the Hydrangea macrophylla X Hydrangea hybrida ‘FRCK 003 S 123’, disclosed in a U.S. Plant patent application Ser. No. 17/506,251 filed concurrently, primarily in sterile flower color. When “blued”, plants of the new Hydrangea have blue-colored sterile flowers whereas plants of ‘FRCK 003 S 123’ have violet blue and white bi-colored sterile flowers. In addition, plants of the new Hydrangea have mophead-type inflorescences whereas plants of ‘FRCK 003 S 123’ have lacecap-type inflorescences.
Plants of the new Hydrangea can be compared to plants of the Hydrangea macrophylla ‘Akanegumo’, not patented. In side-by-side comparisons, plants of the new Hydrangea differ primarily from plants of ‘Akanegumo’ in the following characteristics:
    • 1. Plants of the new Hydrangea have fewer lenticels on the stems than plants of ‘Akanegumo’.
    • 2. Plants of the new Hydrangea have darker green-colored leaves than plants of ‘Akanegumo’.
    • 3. Plants of the new Hydrangea flower later than plants of ‘Akanegumo’.
    • 4. Plants of the new Hydrangea have larger inflorescences with more sterile flowers than plants of ‘Akanegumo’.
    • 5. Sterile flowers of plants of the new Hydrangea are double-types whereas sterile flowers of plants of ‘Akanegumo’ are single-types.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the unique appearance of the new Hydrangea 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 from the color values cited in the detailed botanical description which accurately describe the colors of the new Hydrangea plant.
The photograph at the top of the sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘FRCK 003 S 9’ grown in a container.
The photograph at the bottom of the sheet (FIG. 2) is a close-up view of a typical inflorescence of ‘FRCK 003 S 9’.
 DETAILED BOTANICAL DESCRIPTION
