Claims
What is claimed is:
1. A new and distinct cultivar of Hydrangea plant named `Pinky
Ring`, substantially as herein illustrated and described.
Description
Latin name of genus and species of plant claimed: Hydrangea
macrophylla.
Variety denomination: `Pinky Ring`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Hydrangea plant botanically known as Hydrangea macrophylla and
hereinafter referred to by the cultivar name `Pinky Ring`.
The new cultivar originated in a controlled breeding program in
Kiryu-shi, Japan during June 2011. The objective of the breeding
program was the development of Hydrangea cultivars that have
double-type florets with a picotee flower color pattern and a
compact-upright growth habit.
The new Hydrangea cultivar is the result of cross-pollination. The
female (seed) parent of the new cultivar is a proprietary Hydrangea
macrophylla breeding selection coded KD10, not patented,
characterized by its double-type, lacecap, medium pink-colored
inflorescences, dark green-colored foliage, and moderately
vigorous, compact-upright growth habit. The male (pollen) parent of
the new cultivar is a proprietary Hydrangea macrophylla breeding
selection coded K16, not patented, characterized by its
single-type, lacecap, pink-colored inflorescences having a picotee
flower color pattern, dark green-colored foliage, and moderately
vigorous, compact-upright growth habit. The new cultivar was
discovered and selected as a single flowering plant within the
progeny of the above stated cross-pollination during April 2013 in
a controlled environment in in Kiryu-shi, Japan.
Asexual reproduction of the new cultivar by softwood cuttings since
June 2014 in Kiryu-shi, Japan has demonstrated that the new
cultivar reproduces true to type with all of the characteristics,
as herein described, firmly fixed and retained through successive
generations of such asexual propagation.
SUMMARY OF THE INVENTION
The following characteristics of the new cultivar have been
repeatedly observed and can be used to distinguish `Pinky Ring` as
a new and distinct cultivar of Hydrangea plant: 1. Double-type,
modified lacecap inflorescences, having light pink-colored sterile
florets with a darker pink picotee color pattern; 2. Dark
green-colored foliage; and 3. Moderately vigorous, compact-upright
growth habit.
Plants of the new cultivar differ from plants of the female parent
primarily in having a picotee flower color pattern. Plants of the
new cultivar differ from plants of the male parent primarily in
having a double-type flower.
Of the many commercially available Hydrangea cultivars, the most
similar in comparison to the new cultivar is `Posy-Bouquet Noble
II`, not patented. However, in comparison, plants of the new
cultivar differ from plants of `Posy-Bouquet Noble II` in at least
the following characteristics: 1. Plants of the new cultivar have
florets with a picotee color pattern unlike plants of `Posy-Bouquet
Noble II`; 2. Plants of the new cultivar have a more compact growth
habit than plants of `Posy-Bouquet Noble II`; and 3. Plants of the
new cultivar have darker green-colored foliage than plants of
`Posy-Bouquet Noble II`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show, as nearly true as it is
reasonably possible to make the same in color illustrations of this
type, typical flower and foliage characteristics of the new
cultivar. Colors in the photographs may differ slightly from the
color values cited in the detailed description, which accurately
describes the colors of `Pinky Ring`. The plants were approximately
one-year old and were grown in one-gallon containers in a
poly-covered greenhouse in Kiryu-shi, Japan. Plants were given one
pinch at transplant.
FIG. 1 illustrates a side view of the overall growth and flowering
habit of `Pinky Ring`.
FIG. 2 illustrates an inflorescence with fully-open florets of
`Pinky Ring`.
DETAILED BOTANICAL DESCRIPTION
The new cultivar has not been observed under all possible
environmental conditions to date. Accordingly, it is possible that
the phenotype may vary somewhat with variations in the environment,
such as temperature, light intensity, and day length, without,
however, any variance in genotype.
The chart used in the identification of colors described herein is
The R.H.S. Colour Chart of The Royal Horticultural Society, London,
England, 2007 edition, except where general color terms of ordinary
significance are used. The color values were determined in July
2016 under natural light conditions in Iyo, Japan.
The following descriptions and measurements describe approximately
one-year old plants produced from softwood cuttings from stock
plants and grown under conditions comparable to those used in
commercial practice. The plants were grown in one-gallon containers
in a poly-covered greenhouse in Kiryu-shi, Japan. Plants were given
one pinch at transplant. Day temperatures ranged from a high of
97.degree. F. (36.degree. C.) to a low of 43.degree. F. (6.degree.
C.). Night temperatures ranged from a high of 77.degree. F.
(25.degree. C.) to a low of 25.degree. F. (-4.degree. C.).
Greenhouse light levels of 30,000 lux to 100,000 lux were
maintained during the day. No supplemental lighting was provided.
Measurements and numerical values represent averages of typical
plants. Botanical classification: Hydrangea macrophylla cultivar
