Title: Hydrangea Plant Named ‘HIHAI’
Applicant: Roy Robin van Dijk
Filed: Concurrently with the instant application
STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE
An European Community Plant Breeder's Rights application for the instant plant was filed by the Assignee, Hi Breeding B.V. of De Lier, The Netherlands, on Sep. 9, 2019, application number 2019/2200. Foreign priority is not claimed to this 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 exemption 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 ‘HIFLA’.
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 in March, 2011 of a proprietary selection of Hydrangea macrophylla identified as code number 1340, not patented, as the female, or seed, parent with a proprietary selection of Hydrangea macrophylla identified as code number 1014, 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 in April, 2013.
Asexual reproduction of the new Hydrangea plant by terminal vegetative cuttings since June, 2016 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 ‘HIFLA’. These characteristics in combination distinguish ‘HIFLA’ as a new and distinct Hydrangea plant:
    • 1. Upright and broadly spreading plant habit.
    • 2. Freely branching habit.
    • 3. Strong and sturdy stems.
    • 4. Freely and reblooming flowering habit.
    • 5. Large and dense inflorescences with red purple-colored sterile flowers.
    • 6. 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 the following characteristics:
    • 1. Stems of plants of the new Hydrangea are sturdier than stems of plants of the female parent selection.
    • 2. Leaves of plants of the new Hydrangea are darker green in color than leaves of plants of the female parent selection.
    • 3. Sterile flower sepals of plants of the new Hydrangea are darker red purple green in color than sterile flower sepals of plants of the female parent selection.
    • 4. Sterile flower sepals of plants of the new Hydrangea are more cupped than and not as flat as sterile flower sepals of 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 the following characteristics:
    • 1. Stems of plants of the new Hydrangea are sturdier than stems of plants of the male parent selection.
    • 2. Plants of the new Hydrangea will rebloom whereas plants of the male parent selection do not rebloom.
Plants of the new Hydrangea can be compared to plants of Hydrangea macrophylla ‘HIHAI’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Hydrangea differ primarily from plants of ‘HIHAI’ in the following characteristics:
    • 1. Plants of the new Hydrangea have larger leaves than plants of ‘HIHAI’.
    • 2. Sterile flower sepals of plants of the new Hydrangea are red purple in color whereas sterile flower sepals of plants of ‘HIHAI’ are white in color.
Plants of the new Hydrangea can also be compared to plants of Hydrangea macrophylla ‘Leuchtfeuer’, not patented. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Leuchtfeuer’ in the following characteristics:
    • 1. Stems of plants of the new Hydrangea are sturdier than stems of plants of ‘Leuchtfeuer’.
    • 2. Leaves of plants of the new Hydrangea are glossier than leaves of plants of ‘Leuchtfeuer’.
    • 3. Plants of the new Hydrangea will rebloom whereas plants of ‘Leuchtfeuer’ do not rebloom.
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 is a side perspective view of a typical flowering plant of ‘HIFLA’ grown in a container.
The photograph at the top of the second sheet is a close-up view of a typical inflorescence of ‘HIFLA’, and the photograph at the bottom of the second sheet is a close-up view of typical leaves of ‘HIFLA’.
 DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and in the following description were grown during the early spring in 13-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 lightly levels were about 4,000 lux for 16 hours per day. Plants of the new Hydrangea were pinched one time and were two years old when the photographs and description were 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. Plants are not typically “blued” (treated with aluminum sulfate).
