BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hydrangea plant, botanically known as Hydrangea macrophylla and hereinafter referred to by the name ‘Hokomathyst’.
The new Hydrangea plant is a naturally-occurring whole plant mutation of Hydrangea macrophylla ‘Xian’, not patented. The new Hydrangea plant was discovered and selected by the Inventors as a single flowering plant from within a population of plants of ‘Xian’ in a controlled greenhouse environment in Boskoop, The Netherlands in July, 2006.
Asexual reproduction of the new Hydrangea plant by vegetative cuttings in a controlled greenhouse environment in Boskoop, The Netherlands since August, 2006, 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 environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Hokomathyst’. These characteristics in combination distinguish ‘Hokomathyst’ as a new and distinct cultivar of Hydrangea plant:
    • 1. Broadly upright plant habit.
    • 2. Strong erect stems.
    • 3. Relatively small leaves.
    • 4. Mophead-type inflorescences with red purple-colored flowers with green-colored margins.
Plants of the new Hydrangea differ from plants of the parent, ‘Xian’, in the following characteristics:
    • 1. Plants of the new Hydrangea are more freely flowering than plants of ‘Xian’.
    • 2. Plants of the new Hydrangea and ‘Xian’ differ in flower color.
Plants of the new Hydrangea differ from plants of the Hydrangeas ‘Hokomac’ (U.S. Plant patent application Ser. No. 12/658,051) and ‘Hokomarevo’ (U.S. Plant patent application Ser. No. 12/658,049) primarily in flower color.
Plants of the new Hydrangea can also be compared to plants of Hydrangea ‘Magical Diamond’, not patented. Plants of the new Hydrangea differ primarily from plants of ‘Magical Diamond’ in the following characteristics:
    • 1. Plants of the new Hydrangea are more upright than plants of ‘Magical Diamond’.
    • 2. Plants of the new Hydrangea have stronger stems than plants of ‘Magical Diamond’.
    • 3. Inflorescences of plants of the new Hydrangea are flatter than and not as globular as inflorescences of plants of ‘Magical Diamond’.
    • 4. Sterile flowers of plants of the new Hydrangea have thicker and more durable sepals than sterile flowers of plants of ‘Magical Diamond’.
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 value cited in the detailed botanical description which accurately describe the colors of the new Hydrangea plant.
The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Hokomathyst’ grown in a container.
The photograph at the top of the second sheet is a close-up view of a typical inflorescence of ‘Hokomathyst’.
The photograph at the bottom of the second sheet is a close-up view of typical leaf of ‘Hokomathyst’.
 DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and in the following description were grown in two-liter containers during the late spring in a shaded glass-covered greenhouse in Boskoop, The Netherlands under conditions which closely approximate commercial production conditions. During the production of the plants, day and night temperatures ranged from 16° C. to 17° C. Plants of the new Hydrangea were two years old when the photographs and description were taken.
