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 ‘HICANA14’.

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 2017 of a proprietary selection of Hydrangea macrophylla identified as code number 1563, not patented, as the female, or seed, parent with a proprietary selection of Hydrangea macrophylla identified as code number 1794, 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 2019.

Asexual reproduction of the new Hydrangea plant by terminal vegetative cuttings since July 2019 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 ‘HICANA14’. These characteristics in combination distinguish ‘HICANA14’ as a new and distinct Hydrangea plant:

    • 1. Upright and broadly spreading 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 mophead inflorescences with 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 the following characteristics:

    • 1. Plants of the new Hydrangea have sturdier stems than plants of the female parent selection.
    • 2. Sterile flowers of plants of the new Hydrangea are purplish red in color whereas sterile flowers of plants of the female parent selection are purplish pink in color.

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. Plants of the new Hydrangea are more vigorous than plants of the male parent selection.
    • 2. Plants of the new Hydrangea have sturdier stems than 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 stem strength as stems of plants of the new Hydrangea are sturdier than stems of plants of ‘HBA 202911’. In addition, sterile flowers of plants of the new Hydrangea are purplish red in color whereas sterile flowers of plants of ‘HBA 202911’ are purplish pink in color.

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 ‘HICANA14’ grown in a container.

The photograph on the top of the second sheet (FIG. 2) is a close-up view of a typical flowering plant of ‘HICANA14’.

 DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and in the following description were grown during the late summer 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 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. 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 of the new Hydrangea can be treated with aluminum sulfate to “blue” the flower color.
