An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant, Hydrangea Breeders Association B.V. of De Kwakel, The Netherlands, on Mar. 7, 2023, application number 2023/0571. Foreign priority is not claimed to this application.
The present invention relates to a new and distinct cultivar of Hydrangea plant, botanically known as Hydrangea paniculata, commercially referred to as a panicle Hydrangea and hereinafter referred to by the name ‘HP221905’.
The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands and Lengerich, Germany. The objective of the breeding program was to create new compact and freely-branching Hydrangea plants with strong and sturdy stems, large inflorescences with numerous showy sterile flowers, attractive sterile flower color, high temperature tolerance and good garden performance.
The new Hydrangea plant originated from a self-pollination made by the Inventor during the summer of 2013 in De Kwakel, The Netherlands, of Hydrangea paniculata ‘HP217901’, disclosed in U.S. Plant Pat. No. 30,307. The new Hydrangea plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination in a controlled greenhouse environment in Lengerich, Germany during the summer of 2015.
Asexual reproduction of the new Hydrangea plant by vegetative tip cuttings in a controlled environment in De Kwakel, The Netherlands since the spring of 2017 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 ‘HP221905’. These characteristics in combination distinguish ‘HP221905’ as a new and distinct Hydrangea plant:
-
- 1. Relatively compact, upright to somewhat outwardly spreading and rounded to conical plant habit.
- 2. Vigorous growth habit and rapid growth rate.
- 3. Freely branching habit with strong, thick and sturdy stems.
- 4. Freely and uniformly flowering habit.
- 5. Large pyramidal to conical inflorescences with numerous light yellow green-colored sterile flowers.
- 6. Good garden performance.
Plants of the new Hydrangea can be compared to plants of the parent, ‘HP217901’. Plants of the new Hydrangea differ primarily from plants of ‘HP217901’ in flowering habit as plants of the new Hydrangea have more sterile flowers than inflorescences of plants of ‘HP217901’.
Plants of the new Hydrangea can be compared to plants of Hydrangea paniculata ‘HP221903’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons, plants of the new Hydrangea differ primarily from plants of ‘HP221903’ in the following characteristics:
-
- 1. Plants of the new Hydrangea are shorter than plants of ‘HP221903’.
- 2. Plants of the new Hydrangea are not as freely branching as plants of ‘HP221903’.
- 3. Inflorescences of plants of the new Hydrangea have fewer fertile and sterile flowers than inflorescences of plants of ‘HP221903’.
- 4. Plants of the new Hydrangea have larger sterile flowers than plants of ‘HP221903’.
- 5. Sterile sepals of plants of the new Hydrangea do not change color in the autumn whereas sterile sepals of plants of ‘HP221903’ become purplish red in the autumn.
Plants of the new Hydrangea can be compared to plants of Hydrangea paniculata ‘HP221904’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons, plants of the new Hydrangea differ primarily from plants of ‘HP221904’ in the following characteristics:
-
- 1. Plants of the new Hydrangea are shorter and broader than plants of ‘HP221904’.
- 2. Plants of the new Hydrangea flower earlier than plants of ‘HP221904’.
- 3. Inflorescences of plants of the new Hydrangea are pyramidal to conical in shape whereas inflorescences of plants of ‘HP221904’ are rounded conical in shape.
- 4. Inflorescences of plants of the new Hydrangea have fewer sterile flowers than inflorescences of plants of ‘HP221904’.
- 5. Sterile sepals of plants of the new Hydrangea are whiter in color than sterile sepals of plants of ‘HP221904’.
- 6. Sterile sepals of plants of the new Hydrangea do not change color in the autumn whereas sterile sepals of plants of ‘HP221904’ become purplish red in the autumn.
Plants of the new Hydrangea can also be compared to plants of the Hydrangea paniculata ‘HP217902’, disclosed in U.S. Plant Pat. No. 30,332. In side-by-side comparisons, plants of the new Hydrangea differ primarily from plants of ‘HP217902’ in the following characteristics:
-
- 1. Plants of the new Hydrangea are shorter than plants of ‘HP217902’.
- 2. Lateral branches of plants of the new Hydrangea are not as upright as lateral branches of plants of ‘HP217902’.
- 3. Inflorescences of plants of the new Hydrangea are pyramidal to conical in shape whereas inflorescences of plants of ‘HP217902’ are broadly pyramidal in shape.
- 4. Plants of the new Hydrangea have larger sterile flowers than plants of ‘HP217902’.
- 5. Inflorescences of plants of the new Hydrangea have more fertile flowers and fewer sterile flowers than inflorescences of plants of ‘HP217902’.
- 6. Sepals of sterile flowers of plants of the new Hydrangea are more white in color than sepals of sterile flowers of plants of ‘HP217902’.
- 7. Sterile flowers of plants of the new Hydrangea do not change color in the autumn whereas sterile flowers of plants of ‘HP217902’ become dark pink in color in the autumn.
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 ‘HP221905’ grown in a container.
The photograph on the second sheet (FIG. 2 ) is a close up view of a typical inflorescence of ‘HP221905’.
Plants used in the aforementioned photographs and in the following description were grown during the summer in 17-cm containers in an outdoor nursery in Lengerich, Germany and under cultural practices typical of commercial panicle Hydrangea production. During the production of the plants, day and night temperatures averaged 15 C. Plants of the new Hydrangea were 17 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.
