Description

Botanical designation: Hydrangea macrophylla.

Cultivar denomination: ‘Dancing Angel’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea, botanically known as Hydrangea macrophylla and hereinafter referred to by the name ‘Dancing Angel’.

The new Hydrangea is a naturally-occurring branch mutation of the Hydrangea macrophylla cultivar Pink Candy, not patented. The cultivar Dancing Angel was discovered and selected by the Inventor in April, 2000 from within a population of plants of the parent cultivar in a controlled environment in Honjo-shi, Saitama Prefecture, Japan.

Asexual reproduction of the new cultivar by softwood cuttings in Honjo-shi, Saitama Prefecture, Japan since June, 2000 has shown that the unique features of this new Hydrangea plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The cultivar Dancing Angel has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dancing Angel’. These characteristics in combination distinguish ‘Dancing Angel’ as a new and distinct cultivar of Hydrangea:

    • 1. Upright and mounded plant habit.
    • 2. Strong roots and stems.
    • 3. Strong and dark green-colored leaves that are dark yellow and purple-variegated in the autumn.
    • 4. Large mophead-type inflorescences with pink and red purple bi-colored flowers.

Plants of the new Hydrangea differ primarily from plants of the parent, the cultivar Pink Candy, in foliage and flower color as plants of the cultivar Pink Candy do not have variegated foliage in the autumn and have solid pink-colored flowers.

Plants of the new Hydrangea can be compared to plants of the cultivar Kumiko, disclosed in U.S. Plant Pat. No. 6,924. Plants of the new Hydrangea differ primarily from plants of the cultivar Kumiko in the foliage and flower color as plants of the cultivar Kumiko do not have variegated foliage in the autumn and have purple pink-colored flowers. In addition, plants of the new Hydrangea are more compact and have smaller leaves and flowers than plants of the cultivar Kumiko.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the unique appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Hydrangea.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Dancing Angel’ grown in a container.

The photograph on the second sheet is a top perspective view of a typical plant of ‘Dancing Angel’ during the autumn after the flowers have abscised showing the variegated foliage.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used in the aforementioned photographs and in the following description were grown in Honjo-shi, Saitama Prefecture, Japan in a polyethylene-covered greenhouse and under conditions which closely approximate commercial production conditions.

Plants of the new Hydrangea were about one year old when the photographs and description were taken.
