Abstract
A new and distinct cultivar of Hydrangea plant named ‘Pinky Ring’, characterized by its double-type, modified lacecap inflorescences, having light pink-colored sterile florets with a darker pink picotee color pattern, dark green-colored foliage, and moderately vigorous, compact-upright growth habit, is disclosed.
Description
Latin name of genus and species of plant claimed: Hydrangea macrophylla.
Variety denomination: ‘Pinky Ring’.
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.
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’.
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.
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° F. (36° C.) to a low of 43° F. (6° C.). Night temperatures ranged from a high of 77° F. (25° C.) to a low of 25° F. (−4° 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.
