Abstract
A new cultivar of Hydrangea macrophylla named ‘HORWACK’ that is characterized by its mophead type inflorescences with showy fertile flowers and smaller less numerous non-showy fertile flowers. its showy flowers that are bicolor with bright green and deep pink sepals, its remontant blooming habit, blooming in mid summer and repeat blooming in fall, its remontant blooming habit, its act plant habit with good branching, and its good disease resistance to powdery mildew and botrytis.
Description
Genus/species: Hydrangea macrophylla.
Varietal denomination: ‘HORWACK’.
The present invention relates to a new and distinct cultivar of Hydrangea macrophylla and will be referred to hereafter by its cultivar name, ‘HORWACK’. ‘HORWACK’ represents a new big leaf hydrangea, a perennial shrub grown for landscape use.
‘HORWACK’ arose from an ongoing breeding program by the Inventor with objectives of developing new cultivars of Hydrangea with improved disease resistance, good branching, with induction of primarily sterile flowers.
‘HORWACK’ originated from a cross conducted in the Inventor's trial garden in April of 2004 in Dresden, Germany between the cultivar ‘Green Shadow’ as the female parent and an unnamed plant of Hydrangea macrophylla from the Inventor's breeding program, designated as clone no. 59-96/1. The new Hydrangea was selected as a unique single plant from the progeny of the above cross in April of 2006.
Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings in Dresden, Germany in June of 2006 by the Inventor. Asexual propagation by softwood 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 ‘HORWACK’ as a unique cultivar of Hydrangea macrophylla.
-
- 1. ‘HORWACK’ exhibits showy flowers that are bicolor with bright green and deep pink sepals.
- 2. ‘HORWACK’ exhibits mophead type inflorescences with showy flowers and smaller less numerous non-showy fertile flowers.
- 3. ‘HORWACK’ exhibits a remontant blooming habit, blooming in mid summer and repeat blooming in fall.
- 4. ‘HORWACK’ exhibits a compact plant habit with good branching.
- 5. ‘HORWACK’ exhibits dark green-foliage.
- 6. ‘HORWACK’ has shown resistance to powdery mildew and botrytis.
‘GREEN SHADOW’, the female parent of ‘HORWACK’, differs from ‘HORWACK’ in having showy flowers that are bigger, less numerous, and less bright in coloration and in having less resistance to botrytis. The male parent, clone no. 59-96/1, differs from ‘HORWACK’ in having showy flowers that are dark pink without any green coloration and in having a more vigorous growth habit. ‘HORWACK’ can also be most closely compared to the cultivars; ‘Kolmagics’ (not patented) and ‘HORGEW’ (not patented). Both are similar in having bicolor showy flowers that are pink and green. ‘Kolmagics’ differs from ‘HORWACK’ in having inflorescences that are more ball-shaped and in having showy flower sepals that are more rounded in shape. ‘HORGEW’ differs from ‘HORWACK’ in having showy flower color that is less brilliant and distinct, in having poorer branching, and in having leaves that are lighter green in color.
The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Hydrangea. The plant in the photograph is about one-year-old in age as grown in a greenhouse in a 1-liter container in Dresden, Germany.
The photograph in FIG. 1 provides a view of ‘HORWACK’ in bloom.
The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the new Hydrangea.
The following is a detailed description of one year-old plants of ‘HORWACK’ as grown under greenhouse conditions in one-gallon containers in Abbotsford, B.C., Canada. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
