Claims
It is claimed:
1. A new and distinct Hydrangea plant named `H216906` as
illustrated and described.
Description
Botanical designation: Hydrangea macrophylla.
Cultivar denomination: `H216906`.
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 `H216906`.
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 with numerous showy sterile flowers, attractive
sterile flower color and good postproduction longevity.
The new Hydrangea plant originated from a cross-pollination made by
the Inventor in April, 2012 in De Kwakel, The Netherlands, of a
proprietary selection of Hydrangea macrophylla identified as code
number 10-0169-002, not patented, as the female, or seed, parent
with a proprietary selection of Hydrangea macrophylla identified as
code number 10-0167-091, 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, 2014.
Asexual reproduction of the new Hydrangea plant by vegetative
cuttings in a controlled environment in De Kwakel, The Netherlands
since June, 2014 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 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 `H216906`. These
characteristics in combination distinguish `H216906` as a new and
distinct Hydrangea plant: 1. Upright and rounded plant habit. 2.
Vigorous growth habit and moderate growth rate. 3. Freely branching
habit with strong, thick and sturdy stems. 4. Early, freely and
uniformly flowering habit. 5. Mophead-type inflorescences with
numerous double-type bright red purple-colored sterile flowers. 6.
Good postproduction longevity.
Plants of the new Hydrangea can be compared to plants of the female
and male parent selections. Plants of the new Hydrangea differ
primarily from plants of the female and male parent selections in
sterile flower type as sterile flowers of plants of the new
Hydrangea are double types with several whorls of sepals whereas
sterile flowers of plants of the female and male parent selections
are single types with a single whorl of sepals.
Plants of the new Hydrangea can be compared to plants of a
proprietary selection of Hydrangea macrophylla identified as code
number `12-0133-256`, disclosed in U.S. Patent pre-grant
publication number 20160057954. Although the new Hydrangea and the
proprietary selection have the same parents, in side-by-side
comparisons, plants of the new Hydrangea differ primarily from
plants of the proprietary selection 12-0133-256 in the following
characteristics: 1. Plants of the new Hydrangea are not as compact
as and are more vigorous than plants of the proprietary selection
12-0133-256. 2. Plants of the new Hydrangea have larger leaves than
plants of the proprietary selection 12-0133-256. 3. Sterile flowers
of plants of the new Hydrangea are bright red purple in color
whereas sterile flowers of plants of the proprietary selection
12-0133-256 are dark pink in color.
Plants of the new Hydrangea can also be compared to plants of the
Hydrangea hybrida `Agrihydravijf`, disclosed in U.S. Plant Pat. No.
19,731. In side-by-side comparisons, plants of the new Hydrangea
differ primarily from plants of `Agrihydravijf` in the following
characteristics: 1. Panicles of plants of the new Hydrangea are
broader than panicles of plants of `Agrihydravijf`. 2. Plants of
the new Hydrangea have more sterile flowers per inflorescence than
plants of `Agrihydravijf`. 3. Sterile flowers of plants of the new
Hydrangea are double types with several whorls of sepals whereas
sterile flowers of plants of `Agrihydravijf` are single types with
a single whorl of sepals. 4. Plants of the new Hydrangea have
darker red purple-colored sterile flower sepals than plants of
`Agrihydravijf`. 5. When "blued", plants of the new Hydrangea have
purple-colored sterile flower sepals whereas plants of
`Agrihydravijf` have light violet blue-colored flower sepals.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
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 `H216906`.
The photograph on the second sheet is a close-up view of a typical
inflorescence of that has not been "blued", that is, treated with
aluminum sulfate.
The photograph on the third sheet is a close-up view of a typical
inflorescence of `H216906` that has been "blued".
DETAILED BOTANICAL DESCRIPTION
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.degree. C. Plants of the new Hydrangea were exposed to
a cold (2.degree. to 8.degree. C.) temperature treatment for 6
weeks to break flower bud dormancy. Plants of the new Hydrangea
were pinched one time and were ten months old when the photographs
and description were taken. Plants of the new Hydrangea can be
successfully 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. Botanical description: Hydrangea macrophylla `H216906`.
