Abstract

A new cultivar of Hydrangea macrophylla plant named ‘Hokomasoma’ that is characterized by its mounded and compact growth habit, its inflorescences that are pink in color, its well-branched habit, and its suitability as a potted plant and garden plant.

Description

Botanical classification: Hydrangea macrophylla.

Varietal denomination: ‘Hokomasoma’.

BACKGROUND OF THE INVENTION

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

‘Hokomasoma’ 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 good branching, inflorescences with different shades of pink and suitability as a potted plant and as a garden plant.

‘Hokomasoma’ arose from a controlled cross made by the Inventors in Boskoop, The Netherlands in May of 2014 between an unnamed and unpatented proprietary plant in the Inventor's breeding program, reference no. 12-065-13, as the female parent and Hydrangea ‘Magical Opal’ (U.S. Plant Pat. No. 20,483) as the male parent.

Asexual propagation of the new cultivar was first accomplished by stem cuttings under the direction of the Inventors in July of 2016 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.

SUMMARY OF THE INVENTION

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

• • 1. ‘Hokomasoma’ exhibits a mounded and compact growth habit.
  • 2. ‘Hokomasoma’ exhibits inflorescences that are pink in color.
  • 3. ‘Hokomasoma’ exhibits a well-branched habit.
  • 4. ‘Hokomasoma’ exhibits suitability as a potted plant and garden plant.

The female parent of ‘Hokomasoma’ differs from ‘Hokomasoma’ in having sterile sepals that are picotee in form, longer stems, and leaves that are darker green in color. The male parent of ‘Hokomasoma’ differs from ‘Hokomasoma’ in having longer stems, larger leaves, and inflorescences with more flowers that are darker pink in color. ‘Hokomasoma’ can be most closely compared to the Hydrangea macrophylla cultivars ‘Kolmagimar’ (not patented) and ‘Hokomarore’ (U.S. Plant Pat. No. 31,264). Both ‘Kolmagimar’ and ‘Hokomarore’ are similar to ‘Hokomasoma’ in having pink inflorescences and suitability as a potted plant. ‘Kolmagimar’ differs from ‘Hokomasoma’ in having inflorescences that are slightly darker pink in color, leaf margins that are more dentated, and flower margins that are serrate. ‘Hokomarore’ differs from ‘Hokomasoma’ in having sterile flowers that are more cup-shaped, inflorescence texture that is harder (firmer), and inflorescences with more flowers.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Hydrangea. The photographs were taken of a 1-year-old plant as grown in 2-gallon containers in Abbotsford, British Columbia, Canada.

The photograph in FIG. 1 provides a side view of ‘Hokomasoma’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Hokomasoma’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘Hokomasoma’.

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.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a description of 1-year-old plants as grown outdoors in 2-gallon containers in Abbotsford, British Columbia, Canada. The plants were grown under non-bluing conditions.
