Abstract
A new and distinct cultivar of Hydrangea plant named ‘Hortmablush’, characterized by its upright to broadly spreading plant habit; moderately vigorous growth habit and moderate growth rate; freely branching habit with strong and thick sturdy stems; strong root system; mophead-type inflorescences with numerous red purple and white bi-colored sterile flowers; and good postproduction longevity.
Description
Botanical designation: Hydrangea macrophylla.
Cultivar denomination: ‘HORTMABLUSH’.
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 ‘Hortmablush’.
The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in Boskoop, The Netherlands. The objective of the breeding program was to create new Hydrangea plants with strong root system and large inflorescences with numerous bi-colored sterile flowers and good postproduction longevity.
The new Hydrangea plant originated from a cross-pollination made by the Inventor in April, 2006 in Boskoop, The Netherlands, of a proprietary selection of Hydrangea macrophylla identified as code number 03-015-06, not patented, as the female, or seed, parent with a proprietary selection of Hydrangea macrophylla identified as code number 02-029-06, not patented, as the male, or pollen, parent. The new Hydrangea plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Boskoop, The Netherlands in July, 2014.
Asexual reproduction of the new Hydrangea plant by vegetative terminal cuttings in a controlled environment in Boskoop, The Netherlands 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 ‘Hortmablush’. These characteristics in combination distinguish ‘Hortmablush’ as a new and distinct Hydrangea plant:
-
- 1. Upright to broadly spreading plant habit.
- 2. Moderately vigorous growth habit and moderate growth rate.
- 3. Freely branching habit with strong and thick sturdy stems.
- 4. Strong root system.
- 5. Mophead-type inflorescences with numerous red purple and white bi-colored sterile flowers.
- 6. Good postproduction 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 sterile flower color as sterile flower sepals of plants of the female parent selection are solid red purple 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 growth habit as plants of the new Hydrangea are stronger and have stronger root systems than plants of the male parent selection. In addition, plants of the new Hydrangea are more freely branching than plants of the male parent selection.
Plants of the new Hydrangea can be compared to plants of the Hydrangea macrophylla ‘Harlequin’, not patented. In side-by-side comparisons plants of the new Hydrangea differ primarily from plants of ‘Harlequin’ in the following characteristics:
-
- 1. Plants of the new Hydrangea are more compact than and not as tall as plants of ‘Harlequin’.
- 2. Plants of the new Hydrangea are more freely branching than plants of ‘Harlequin’.
- 3. Plants of the new Hydrangea have stronger lateral branches than plants of ‘Harlequin’.
- 4. Plants of the new Hydrangea have sturdier sterile flowers than plants of ‘Harlequin’.
Plants of the new Hydrangea can also be compared to plants of the Hydrangea macrophylla ‘Hortmaserena’, not patented. In side-by-side comparisons plants of the new Hydrangea differ primarily from plants of ‘Hortmaserena’ in the following characteristics:
-
- 1. Plants of the new Hydrangea have shorter lateral branches than plants of ‘Hortmaserena’.
- 2. Plants of the new Hydrangea and ‘Hortmaserena’ differ in sterile flower color as plants of ‘Hortmaserena’ have sterile flower sepals that are darker red purple in color with narrower white-colored margins.
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 ‘Hortmablush’.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Hortmablush’.
Plants used in the aforementioned photographs and in the following description were grown during the late spring 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 18° C. to 25° C. 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. 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.
