Abstract

A new cultivar of Hydrangea macrophylla plant named ‘Hokomalega’ that is characterized by its very floriferous blooming habit, its sterile flowers that have sepals with crenate margins, its inflorescences that are pink in color with a touch of green, and its suitability as a potted plant.

Description

Botanical classification: Hydrangea macrophylla.

Varietal denomination: ‘Hokomalega’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is related to U.S. Plant Patents for a plant derived from the same breeding program that is entitled Hydrangea Plant Named ‘Hokomac’ (U.S. Plant Pat. No. 22,259).

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, ‘Hokomalega’. ‘Hokomalega’ represents a new bigleaf Hydrangea, a perennial shrub grown for landscape use and as a potted plant.

‘Hokomalega’ derived from an ongoing controlled breeding program directed by the Inventors. An objective of the breeding program included developing a new cultivar of Hydrangea with pink flowers, a floriferous blooming habit and other desirable traits.

‘Hokomalega’ arose from a controlled cross made by the Inventors in Boskoop, The Netherlands in May of 2007 between Hydrangea ‘Hokomac’ as the female parent and Hydrangea ‘Glowing Alps’ (not patented) as the male parent. ‘Hokomalega’ was selected as a single unique plant from amongst the resulting seedlings in June of 2009.

Asexual propagation of the new cultivar was first accomplished by stem cuttings by one of the Inventors in August of 2009 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 ‘Hokomalega’ as a unique cultivar of Hydrangea macrophylla.

- 1. ‘Hokomalega’ exhibits a very floriferous blooming habit.
- 2. ‘Hokomalega’ exhibits sterile flowers that have sepals with crenate margins.
- 3. ‘Hokomalega’ exhibits inflorescences that are pink in color with a touch of green.
- 4. ‘Hokomalega’ exhibits suitability as a potted plant.

The female parent of ‘Hokomalega’ differs from ‘Hokomalega’ in having sterile sepals that have more green coloration, less crenate margins and a more flattened mophead. The male parent of ‘Hokomalega’ differs from ‘Hokomalega’ in having a darker pink inflorescence and sepals with smooth margins and no green coloration. ‘Hokomalega’ can be most closely compared to the Hydrangea macrophylla cultivars ‘Hortmacaro’ (U.S. Plant Pat. No. 31,263) and ‘Hokomapiclo’ (not patented). ‘Hortmacaro’ and ‘Hokomapiclo’ are both similar to ‘Hokomalega’ in having sterile flowers that are pink in color with sepals that have crenate margins. ‘Hortmacaro’ differs from ‘Hokomalega’ in having a different shaped mophead, leaves and sterile sepal margins that are more crenate and a firmer sterile sepal texture. ‘Hokomapiclo’ differs from ‘Hokomalega’ in having inflorescences that are lighter pink in color, sterile flowers with sepals that are more green in color with larger crenated margins.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

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 disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hydrangea. The photographs were taken of a two-year-old plant of ‘Hokomalega’ as grown in a greenhouse in a 17-cm container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a side view of the plant habit of ‘Hokomalega’ in bloom.

The photograph in FIG. 2 provides a close-up view of a fully open inflorescence of ‘Hokomalega’.

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

The photograph in FIG. 4 provides a view of an inflorescence when plants were grown with aluminum sulfate and a soil pH of <6.5.

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.
