Abstract

A new cultivar of Hydrangea macrophylla named ‘Fanfare’ that is characterized by its ability to re-bloom on new growth after deadheading, its consistently formed rounded, hortensia type inflorescences with sepals that are round to broadly elliptic in shape and blue in color with white to pale pink margins when grown under acidic soil conditions and pink in color with white margins when grown under alkaline soil conditions, its compact growth habit with strong stems that enable pot culture without the need for staking, its dark green glossy foliage and its hardiness at least in U.S.D.A. Zones 5 to 9.

Description

Botanical classification: Hydrangea macrophylla.

Varietal denomination: ‘Fanfare’.

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, ‘Fanfare’. ‘Fanfare’ represents a new mophead type bigleaf hydrangea, a deciduous shrub grown for landscape use and for use as a potted plant.

‘Fanfare’ was derived from an ongoing controlled breeding program in a nursery that focuses on new cultivars of bigleaf hydrangeas for container and landscape use. ‘Fanfare’ originated from a cross made in the Inventor's nursery in June 1999 in Shizuoka, Japan between an unpatented proprietary selection of Hydrangea macrophylla designated as H3-67 as the female and Hydrangea macrophylla ‘Alexsandria’ (not patented) as the male parent. The new Hydrangea was selected as a unique single plant from the progeny of the cross in March 2006.

Asexual reproduction of the new cultivar was first accomplished by softwood stem cuttings by the Inventor in Shizuoka, Japan in May 2007. The characteristics of this cultivar have been determined to be 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 ‘Fanfare’ as a unique cultivar of Hydrangea macrophylla.

- 1. ‘Fanfare’ is a strong bloomer and exhibits a re-blooming habit with inflorescences produced from early summer until fall with removal of spent blooms; observed in Shizuoka, Japan, Niagara on the Lake, Ontario, Canada, and Warsaw, N.C.
- 2. ‘Fanfare’ exhibits consistently formed hortensia type inflorescences that are rounded in shape.
- 3. The sterile flowers of ‘Fanfare’ exhibit sepals that are round to broadly elliptic in shape with marginal variegation; blue in color with white to pale pink margins when grown under acidic soil conditions and pink in color with white margins when grown under alkaline soil conditions.
- 4. ‘Fanfare’ exhibits a compact growth habit with strong stems that enable pot culture without the need for staking.
- 5. ‘Fanfare’ exhibits dark green glossy foliage.
- 6. ‘Fanfare’ is hardy at least to U.S.D.A. Zones 5 to 9.

The new cultivar of Hydrangea differs from its parents, H3-67 and ‘Alexsandria’, in having sterile flowers with sepals that exhibit marginal variegation whereas the sepals of the parent plants are non-variegated. ‘Fanfare’ can be most closely compared to the cultivar ‘Harlequin’ (not patented) which also exhibits sterile flowers with white variegated sepal margins and in having similar foliage characteristics. ‘Harlequin’ differs from ‘Fanfare’ in having sterile flowers sepals that are deep pink in color with white margins and also differs in blooming on old wood and lacking a reblooming habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the newHydrangea.

The photographs were taken of three year-old plants of ‘Fanfare’ as grown outdoors in three-gallon containers in Shizuoka, Japan.

The photograph in FIG. 1 illustrates the foliage, flowering habit and plant habit as observed when grown under acidic soil conditions.

The photograph in FIG. 2 illustrates a close-up view of inflorescences of ‘Fanfare’ as grown under acidic soil conditions.

The photograph in FIG. 3 illustrates a close-up view of inflorescences of ‘Fanfare’ as grown under alkaline soil conditions.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Hydrangea.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of a three year-old plants of ‘Fanfare’ as grown outdoors in three-gallon container in Shizuoka, Japan. The detailed data was taken from plants growing under alkaline conditions with color data provided for the flowers of plants grown under acidic condition were differences exist. Phenotypic differences may be observed with variations in environmental, climatic, and cultural 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.
