Ser. No. 15/999,929
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 ‘Hokomagrevo’.
The new Hydrangea is a naturally-occurring whole plant mutation of Hydrangea macrophylla ‘Hokomarevo’, disclosed in U.S. Plant Pat. No. 22,260. The new Hydrangea plant was discovered and selected by the Inventors as a single flowering plant from within a population of plants of ‘Hokomarevo’ in a controlled greenhouse environment in Boskoop, The Netherlands on Jun. 24, 2015.
Asexual reproduction of the new Hydrangea plant by vegetative terminal cuttings in a controlled environment in Boskoop, The Netherlands since August, 2015 has shown that the unique features of this new Hydrangea plant are stable and reproduced true to type in successive generations.
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 ‘Hokomagrevo’. These characteristics in combination distinguish ‘Hokomagrevo’ as a new and distinct Hydrangea plant:
-
- 1. Compact, upright and somewhat outwardly spreading plant habit.
- 2. Moderately vigorous to vigorous growth habit and moderate growth rate.
- 3. Freely branching habit with strong and thick sturdy stems.
- 4. Freely flowering habit.
- 5. Compact mophead-type inflorescences with green, white and light purple-colored sterile flowers.
- 6. Good postproduction longevity.
Plants of the new Hydrangea can be compared to plants of the mutation parent, ‘Hokomarevo’. Plants of the new Hydrangea differ primarily from plants of ‘Hokomarevo’ in sterile flower color as sterile flower sepals of plants of the new Hydrangea are green, white and light purple in color whereas sterile flower sepals of plants of ‘Hokomarevo’ are red purple in color becoming red purple and green with development.
Plants of the new Hydrangea can be compared to plants of Hydrangea macrophylla ‘Hokomarore’, disclosed in U.S. Plant patent application Ser. No. 15/999,929. Plants of the new Hydrangea differ primarily from plants of ‘Hokomarore’ in sterile flower color as sterile flower sepals of plants of the new Hydrangea are green, white and light purple in color whereas sterile flower sepals of plants of ‘Hokomarore’ are red purple in color.
Plants of the new Hydrangea can be compared to plants of the Hydrangea macrophylla ‘Hokomathyst’, disclosed in U.S. Plant Pat. No. 22,261. In side-by-side comparisons plants of the new Hydrangea differ primarily from plants of ‘Hokomathyst’ in the following characteristics:
-
- 1. Plants of the new Hydrangea are more compact than plants of ‘Hokomathyst’.
- 2. Plants of the new Hydrangea are more outwardly spreading than and not as upright as plants of ‘Hokomathyst’.
- 3. Plants of the new Hydrangea have smaller inflorescences than plants of ‘Hokomathyst’.
- 4. Plants of the new Hydrangea differ from plants of ‘Hokomathyst’ in sterile flower color as sterile flower sepals of plants of the new Hydrangea are green, white and light purple in color whereas sterile flower sepals of plants of ‘Hokomathyst’ are red purple in color with green-colored margins.
Plants of the new Hydrangea can be compared to plants of the Hydrangea macrophylla ‘Hortmagreclo’, disclosed in U.S. Plant Pat. No. 28,063. In side-by-side comparisons plants of the new Hydrangea differ primarily from plants of ‘Hortmagreclo’ in the following characteristics:
-
- 1. Plants of the new Hydrangea are more compact than plants of ‘Hortmagreclo’.
- 2. Plants of the new Hydrangea have smaller inflorescences than plants of ‘Hortmagreclo’.
- 3. Plants of the new Hydrangea differ from plants of ‘Hortmagreclo’ in sterile flower color as sterile flower sepals of plants of the new Hydrangea are green, white and light purple in color whereas sterile flower sepals of plants of ‘Hortmagreclo’ are green to dark green in color.
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 ‘Hokomagrevo’ grown in a container.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical inflorescence of ‘Hokomagrevo’.
Plants used in the aforementioned photographs and in the following description were grown during the summer in 17-cm containers in a glass-covered greenhouse in Boskoop, 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. and night temperatures ranged from 10° C. to 22° C. Plants of the new Hydrangea were two years old when the photographs and description were taken. Plants of the new Hydrangea are not typically treated with aluminum sulfate to “blue” the inflorescences. 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.
