plant named ‘Hokomalure’

Abstract

A new cultivar of Hydrangea macrophylla plant named ‘Hokomalure’ that is characterized by its leaves that are very dark brown-red in color, its sterile flowers that are picotee colored (yellow and pink) when young and mature to pink, its sterile sepal edges that are crenate, its upright plant habit, and its suitability as a potted plant.

Description

Botanical classification: Hydrangea macrophylla.

Varietal denomination: ‘Hokomalure’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is related to U.S. Plant Patents for a plant derived from the same breeding program that are entitled Hydrangea Plant Named ‘Hortfire’ (U.S. Pat. No. 29,058) and Hydrangea Plant Named ‘Horthamp’ (U.S. Plant Pat. No. 29,005).

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

‘Hokomalure’ 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 dark leaves, a floriferous blooming habit and other desirable traits.

‘Hokomalure’ arose from a controlled cross made by one of the Inventors in Boskoop, The Netherlands in June of 2012 between Hydrangea ‘Sweet Fantasy’ (not patented) as the female parent and an unnamed and unpatented proprietary plant in the Inventor's breeding program (reference no. 07-120-08) as the male parent. ‘Hokomalure’ was selected as a single unique plant from amongst the resulting seedlings in August of 2014.

Asexual propagation of the new cultivar was first accomplished by stem cuttings by one of the Inventors in August of 2014 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 ‘Hokomalure’ as a unique cultivar of Hydrangea macrophylla.

• 1. ‘Hokomalure’ exhibits leaves that are very dark brown-red in color.
• 2. ‘Hokomalure’ exhibits sterile flowers with sepal edges that are crenate.
• 3. ‘Hokomalure’ exhibits an upright plant habit.
• 4. ‘Hokomalure’ exhibits suitability as a potted plant.
• 5. ‘Hokomalure’ exhibits picotee colored sterile flowers when young (yellow and pink) that mature to pink.

The female parent of ‘Hokomalure’ differs from ‘Hokomalure’ in having sterile flower sepals that are pink with dark pink stripes and smooth margins and in having green leaves. The male parent of ‘Hokomalure’ differs from ‘Hokomalure’ in having leaves that are lighter red in color and sterile flower sepals that are more picotee in color. ‘Hokomalure’ can be most closely compared to the Hydrangea macrophylla cultivars ‘Hortfire’ and ‘Horthamp’. ‘Hortfire’ is similar to ‘Hokomalure’ in having sterile flower sepals that are picotee colored and in having with deeper crenate margins, lighter color leaves and a more floriferous blooming habit. ‘Horthamp’ is similar to ‘Hokomalure’ in having sterile flower sepals that are picotee colored, dark color leaves and an upright growing habit. ‘Horthamp’ differs from ‘Hokomalure’ in having sterile flower sepals with a more intense flower color and smooth margins, leaves that are lighter in color, and a more floriferous blooming habit.
