Description

Botanical designation: Hydrangea macrophylla.
Cultivar denomination: ‘HIMEA’.
STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE
An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee of the instant application, Hi Breeding B.V. of De Lier, The Netherlands on Nov. 15, 2021, application number 2021/2936. Foreign priority is not claimed to this European Plant Breeder's Rights application.
The Inventor/Applicant 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 Inventor/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or 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, commercially referred to as a mophead-type Hydrangea and hereinafter referred to by the name ‘HIMEA’.
The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program is to create new sturdy and strong Hydrangea plants with attractive inflorescences and good postproduction longevity.
The new Hydrangea plant originated from a cross-pollination on Apr. 5, 2016 of a proprietary selection of Hydrangea macrophylla identified as code number 1452, not patented, as the female, or seed, parent with a proprietary selection of Hydrangea macrophylla identified as code number 1671, not patented, as the male, or pollen, parent. The new Hydrangea plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Lier, The Netherlands on Apr. 12, 2018.
Asexual reproduction of the new Hydrangea plant by terminal vegetative cuttings since Jul. 12, 2018 in a controlled greenhouse environment in De Lier, The Netherlands has shown that the unique features of this new Hydrangea plant are stable and reproduced true to type in successive generations of asexual reproduction.
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 ‘HIMEA’. These characteristics in combination distinguish ‘HIMEA’ as a new and distinct Hydrangea plant:
    • 1. Compact, upright and broadly outwardly spreading and mounding plant habit.
    • 2. Moderately vigorous and moderate growth rate.
    • 3. Freely branching habit.
    • 4. Strong and sturdy stems.
    • 5. Dark green-colored leaves.
    • 6. Freely flowering habit.
    • 7. Large and dense inflorescences with vivid purplish red-colored sterile flowers.
    • 8. Good post-production longevity.
Plants of the new Hydrangea can be compared to plants of the female parent selection. Plants of the new Hydrangea differ primarily from plants of the female parent selection in growth habit as plants of the new Hydrangea are not as vigorous as plants of the female parent selection.
Plants of the new Hydrangea can be compared to plants of the male parent selection. Plants of the new Hydrangea differ primarily from plants of the male parent selection in stein strength as stems of plants of the new Hydrangea are sturdier than stems of plants of the male parent selection. In addition, sepals of sterile flowers of plants of the new Hydrangea are lighter in color than sepals of sterile flowers of plants of the male parent selection.
Plants of the new Hydrangea can be compared to plants of Hydrangea macrophylla ‘HBA 202911’, not patented. In side-by-side comparisons, plants of the new Hydrangea differ primarily from plants of ‘HBA 202911’ in the following characteristics:
    • 1. Stems of plants of the new Hydrangea are sturdier than stems of plants of ‘HBA 202911’.
    • 2. Sepals of sterile flowers of plants of the new Hydrangea are lighter in color than sepals of sterile flowers of plants of ‘HBA 202911’.
Plants of the new Hydrangea can also be compared to plants of Hydrangea macrophylla ‘LAVBLAA’, not patented. In side-by-side comparisons, plants of the new Hydrangea differ primarily from plants of ‘LAVBLAA’ in the following characteristics:
    • 1. Stems of plants of the new Hydrangea are sturdier than stems of plants of ‘LAVBLAA’.
    • 2. Sepals of sterile flowers of plants of the new Hydrangea are lighter in color than sepals of sterile flowers of plants of ‘LAVBLAA’.
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 on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘HIMEA’ grown in a container.
The photograph at the top of the second sheet (FIG. 2) is a close-up view of typical inflorescences of ‘HIMEA’.
The photograph at the bottom of the second sheet (FIG. 3) is a close-up view of typical leaves of ‘HIMEA’.
The photograph on the third sheet (FIG. 4) is a top perspective view of a typical flowering plant of ‘HIMEA’ that has been treated with aluminum sulfate, or “blued”.
 DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and in the following description were grown during the late winter and early spring in 14-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under cultural practices typical of commercial Hydrangea production. During the production of the plants, day temperatures ranged from 20° C. to 35° C., night temperatures ranged from 10° C. to 22° C. and light levels averaged 4,000 lux. Plants of the new Hydrangea were pinched one time and were 18 months old when the photographs and description were taken.
