Abstract
A new and distinct cultivar of Hydrangea plant named ‘HYLV17522’, characterized by its relatively compact, upright to broadly spreading and mounding plant habit; moderately vigorous growth habit; freely branching habit; strong and sturdy stems; freely flowering habit; panicles with yellowish green-colored sterile flowers that become dark red in color with subsequent development; and good garden performance.
Description
Botanical designation: Hydrangea paniculata.
Cultivar denomination: ‘HYLV17522’.
An European Community Plant Breeder's Rights application for this plant was filed by the Applicant/Assignee of the instant application, Kwekerij Lendert de Vos of Reeuwijk, The Netherlands on Sep. 24, 2021, application number 2021/2376. Foreign priority is not claimed to this European Plant Breeder's Rights application.
The present invention relates to a new and distinct cultivar of Hydrangea plant, botanically known as Hydrangea paniculata, commercially referred to as a Paniculated Hydrangea and hereinafter referred to by the name ‘HYLV17522’.
The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in Reeuwijk, The Netherlands. The objective of the breeding program is to create new compact and strong Hydrangea plants with attractive inflorescences and good postproduction longevity.
The new Hydrangea plant originated from an open-pollination during the summer of 2015 of a proprietary selection of Hydrangea paniculata identified as code number P13502, not patented, as the female, or seed, parent with an unknown selection of Hydrangea paniculata 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 open-pollination in a controlled greenhouse environment in Reeuwijk, The Netherlands in August, 2017.
Asexual reproduction of the new Hydrangea plant by terminal vegetative cuttings since August, 2017 in a controlled greenhouse environment in Reeuwijk, 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.
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 ‘HYLV17522’. These characteristics in combination distinguish ‘HYLV17522’ as a new and distinct Hydrangea plant:
-
- 1. Relatively compact, upright to broadly spreading and mounding plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Strong and sturdy stems.
- 5 Freely flowering habit.
- 6. Panicles with yellowish green-colored sterile flowers that become dark red in color with subsequent development.
- 7. Good garden performance.
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. Inflorescences of plants of the new Hydrangea are taller and more conical in shape than inflorescences of plants of the female parent selection.
- 2. Sterile flowers of plants of the new Hydrangea are yellowish green in color becoming dark red at the end of the flowering season whereas sterile flowers of plants of the female parent selection are white in color.
Plants of the new Hydrangea can be compared to plants of Hydrangea paniculata ‘HYLV17520’, disclosed in U.S. Plant patent application Ser. No. 18/101,574 filed concurrently. In side-by-side comparisons, plants of the new Hydrangea differ primarily from plants of ‘HYLV17520’ in the following characteristics:
-
- 1. Plants of the new Hydrangea are taller and somewhat more outwardly spreading than plants of ‘HYLV17520’.
- 2. Plants of the new Hydrangea have longer leaves than plants of ‘HYLV17520’.
- 3. Inflorescences of plants of the new Hydrangea are taller and narrower than inflorescences of plants of ‘HYLV17520’.
- 4. Inflorescences of plants of the new Hydrangea have more sterile flowers than inflorescences of plants of ‘HYLV17520’.
Plants of the new Hydrangea can also be compared to plants of Hydrangea paniculata ‘Diamant Rouge’, not patented. In side-by-side comparisons, plants of the new Hydrangea differ primarily from plants of ‘Diamant Rouge’ in the following characteristics:
-
- 1. Plants of the new Hydrangea are more compact and shorter than plants of ‘Diamant Rouge’.
- 2. Plants of the new Hydrangea are denser and have stronger and sturdier stems than plants of ‘Diamant Rouge’.
- 3. Inflorescences of plants of the new Hydrangea are denser and more uniform in shape than inflorescences of plants of ‘Diamant Rouge’.
- 4. Inflorescences of plants of the new Hydrangea have smaller sterile flowers than inflorescences of plants of ‘Diamant Rouge’.
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.
Plants used in the aforementioned photographs and in the following description were grown during the summer in 21-cm containers in an outdoor nursery in Reeuwijk, The Netherlands and under cultural practices typical of commercial Hydrangea production. During the production of the plants, day temperatures ranged from 18° C. to 30° C., night temperatures ranged from 8° C. to 18° C. Plants of the new Hydrangea were pinched in the early summer. Plants were three 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. Paniculated Hydrangea plants are not typically treated with aluminum sulfate to “blue” the flower color.
