Botanical classification: Hydrangea macrophylla.

Varietal denomination: ‘Hokomapfloy’.


The present invention relates to a new and distinct cultivar of Hydrangea macrophylla and will be referred to hereafter by its cultivar name, ‘Hokomapfloy’. ‘Hokomapfloy’ represents a new bigleaf Hydrangea, a perennial shrub grown for use in the landscape, as a potted plant, and as a cut flower.

‘Hokomapfloy’ derived from an ongoing controlled breeding program directed by the Inventors. The goal of the breeding program included developing a new cultivar of Hydrangea with hard (sturdy) textured flowers and suitability as a potted plant and as a cut flower.

‘Hokomapfloy’ arose from a controlled cross made by the Inventors in Boskoop, The Netherlands in May of 2006 between unnamed and unpatented proprietary plants in the Inventor's breeding program, reference no. 03-058-01 as the female parent and reference no. 03-056-01 as the male parent. The new cultivar was selected as a single unique plant in May of 2008 from the resulting seedling from the above cross.

Asexual propagation of the new cultivar was first accomplished by stem cuttings under the direction of the Inventors in July of 2008 in Boskoop, The Netherlands. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.


The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Hokomapfloy’ as a unique cultivar of Hydrangea macrophylla.

    • 1. ‘Hokomapfloy’ exhibits a compact, densely branched and rounded plant habit.
    • 2. ‘Hokomapfloy’ exhibits clear pink inflorescences that as also perform well under bluing conditions.
    • 3. ‘Hokomapfloy’ exhibits mophead inflorescences with a hard (sturdy) texture.
    • 4. ‘Hokomapfloy’ exhibits suitability as a potted plant and for cut flowers.
    • 5. ‘Hokomapfloy’ exhibits unique cup-shaped sterile flowers.

Both the female and male parent of ‘Hokomapfloy’ differ from ‘Hokomapfloy’ in having inflorescences that are red in color and sterile flowers that are less cup-shaped. ‘Hokomapfloy’ can be most closely compared to the Hydrangea macrophylla cultivars ‘Verena’ (not patented) and ‘Magical Opal’ (U.S. Plant Pat. No. 20,483). Both ‘Verena’ and ‘Magical Opal’ are similar to ‘Hokomapfloy’ in having pink inflorescences that perform well under bluing conditions and suitability for growing as a cut flower. Both ‘Verena’ and ‘Magical Opal’ differ from ‘Hokomapfloy’ in having less sterile flowers per inflorescence, sterile flowers that are less cup-shaped, and inflorescences that are softer in texture.


The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosures and/or sales that fall within a one-year grace period to the filing date. Disclosures include a website listing by Monrovia.


The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Hydrangea. The photographs were taken of plants 3 years in age as grown outdoors in 5-liter containers in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a side view of the inflorescences ‘Hokomapfloy’ in bloom when grown under bluing conditions.

The photograph in FIG. 2 provides a view of the inflorescences of ‘Hokomapfloy’ when grown under non-bluing conditions.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Hydrangea.


The following is a detailed description of 2-year-old plants of ‘Hokomapfloy’ as grown outdoors in 2-gallon containers in Dayton, Oregon and grown under bluing conditions (with exception of sterile sepal color provided as well when grown under non-bluing conditions). The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
