Abstract

A new and distinct cultivar of Hydrangea plant named ‘HIFIR’, characterized by its upright and broadly spreading plant habit; freely branching habit; strong and sturdy stems; freely and continuous flowering habit; large and dense inflorescences with red to red purple-colored sterile flowers; and good post-production longevity.

Description

Botanical designation: Hydrangea macrophylla.

Cultivar denomination: ‘HIFIR’.

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 ‘HIFIR’.

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 April, 2013 of two unnamed proprietary selections of Hydrangea macrophylla, not patented. 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, 2015.

Asexual reproduction of the new Hydrangea plant by terminal vegetative cuttings since June, 2015 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 ‘HIFIR’. These characteristics in combination distinguish ‘HIFIR’ 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 continuous flowering habit.
    • 5. Large and dense inflorescences with red to red purple-colored sterile flowers.
    • 6. Good post-production longevity.

Plants of the new Hydrangea can be compared to plants of the parent selections. Plants of the new Hydrangea differ primarily from plants of the parent selections in the following characteristics:

    • 1. Plants of the new Hydrangea are sturdier than plants of the parent selections.
    • 2. Plants of the new Hydrangea have longer postproduction longevity than plants of the parent selections.

Plants of the new Hydrangea can also be compared to plants of Hydrangea macrophylla ‘Hot Red’, not patented. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Hot Red’ in the following characteristics:

    • 1. Leaves of plants of the new Hydrangea are darker green in color than leaves of plants of ‘Hot Red’.
    • 2. Sterile flowers of plants of the new Hydrangea are sturdier than sterile flowers of plants of ‘Hot Red’.
    • 3. Sepals of sterile flowers of plants of the new Hydrangea are more undulate than sepals of sterile flowers of plants of ‘Hot Red’.
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 of 2) is a side perspective view of a typical flowering plant of ‘HIFIR’ grown in a container.

The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical inflorescence of ‘HIFIR’.

 DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and in the following description were grown during the autumn 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. 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).
