Description
Botanical designation: Hydrangea macrophylla.
Cultivar denomination: ‘HBA 214903’.
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 ‘HBA 214903’.
The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program was to create new freely-branching Hydrangea plants with strong sturdy stems, large inflorescences, attractive flower color and good postproduction longevity.
The new Hydrangea plant originated from a cross-pollination made by the Inventor in April, 2008 in De Kwakel, The Netherlands, of a proprietary selection of Hydrangea macrophylla identified as code number 617, not patented, as the female, or seed, parent with a proprietary selection of Hydrangea macrophylla identified as code number 03-0134-055, 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 De Kwakel, The Netherlands in March, 2010.
Asexual reproduction of the new Hydrangea plant by vegetative cuttings in a controlled environment in De Kwakel, The Netherlands since June, 2010 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 ‘HBA 214903’. These characteristics in combination distinguish ‘HBA 214903’ as a new and distinct Hydrangea plant:
-
- 1. Upright plant habit; vigorous growth habit.
- 2. Rapid growth rate; freely branching habit.
- 3. Strong and sturdy stems.
- 4. Freely and uniformly flowering habit; does not require a cold temperature treatment for flower initiation and development.
- 5. Mophead-type inflorescences with numerous pink-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 sepal color as plants of the new Hydrangea have darker pink-colored sterile flower sepals than plants of the female parent selection.
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 more vigorous than plants of the male parent selection.
Plants of the new Hydrangea can be compared to plants of the Hydrangea hybrida ‘Agrihydravijf’, disclosed in U.S. Plant Pat. No. 19,731. In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new Hydrangea differ from plants of ‘Agrihydravijf’ in the following characteristics:
-
- 1. Plants of the new Hydrangea are faster-growing than plants of ‘Agrihydravijf’.
- 2. Plants of the new Hydrangea have broader leaves than plants of ‘Agrihydravijf’.
- 3. Plants of the new Hydrangea do not require a cold treatment for flower initiation and development whereas plants of ‘Agrihydravijf’ require a cold treatment for flower initiation and development.
- 4. Plants of the new Hydrangea have more sterile flowers per inflorescence than plants of ‘Agrihydravijf’.
- 5. Sepal margins of sterile flowers of plants of the new Hydrangea are entire whereas sepal margins of sterile flowers of ‘Agrihydravijf’ are serrate to crenate.
- 6. Plants of the new Hydrangea have darker pink-colored sterile flower sepals than plants of ‘Agrihydravijf’.
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 ‘HBA 214903’.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘HBA 214903’.
Plants used in the aforementioned photographs and in the following description were grown during the spring in 13-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial Hydrangea production. During the production of the plants, day and night temperatures averaged 17° C. Plants of the new Hydrangea were five months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
