Abstract

A new and distinct cultivar of Hydrangea plant named ‘HBAnavy’, characterized by its upright and somewhat outwardly spreading plant habit; vigorous growth habit; strong and sturdy stems; freely flowering habit; and large inflorescences with numerous violet blue-colored sterile flowers.

Description

Botanical designation: Hydrangea macrophylla.
Cultivar denomination: ‘HBAnavy’.
BACKGROUND OF THE INVENTION
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 ‘HBAnavy’.
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 and 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, 2007 in De Kwakel, The Netherlands, of a proprietary selection of Hydrangea macrophylla identified as code number 202131-008, not patented, as the female, or seed, parent with a proprietary selection of Hydrangea macrophylla identified as code number 203158-006, 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, 2009.
Asexual reproduction of the new Hydrangea plant by vegetative cuttings in a controlled environment in De Kwakel, The Netherlands since June, 2009 has shown that the unique features of this new Hydrangea plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Hydrangea have not been observed under all possible 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 ‘HBAnavy’. These characteristics in combination distinguish ‘HBAnavy’ as a new and distinct Hydrangea plant:
    • 1. Upright and somewhat outwardly spreading plant habit.
    • 2. Vigorous growth habit.
    • 3. Strong and sturdy stems.
    • 4. Freely flowering habit.
    • 5. Large inflorescences with numerous violet blue-colored sterile flowers.
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 female parent selection in the following characteristics:
    • 1. Plants of the new Hydrangea and the female parent selection differ in sterile flower color as plants of the female parent selection have lighter blue-colored sterile flowers.
    • 2. Plants of the new Hydrangea have better postproduction longevity 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 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 ‘Elbtal’, not patented. In side-by-side comparisons conducted in Glandorf, Germany, plants of the new Hydrangea differed from plants of ‘Elbtal’ in the following characteristics:
    • 1. Plants of the new Hydrangea had thicker and stronger lateral branches than plants of ‘Elbtal’.
    • 2. Plants of the new Hydrangea had larger inflorescences than plants of ‘Elbtal’.
    • 3. Plants of the new Hydrangea and ‘Elbtal’ differed in sterile flower color as plants of ‘Elbtal’ had light blue-colored sterile flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates 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 photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Hydrangea plant.
The photograph comprises a side perspective view of a typical inflorescence and leaves of ‘HBAnavy’.
 DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photograph and in the following description were grown during the spring and summer in 17-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial Hydrangea production.
