Abstract

A new and distinct cultivar of Hydrangea plant named ‘Saxbicodapi’, characterized by its upright and mounded plant habit; moderately vigorous to vigorous growth habit; strong stems; and large mophead-type inflorescences with red purple and green-colored sterile flowers and when treated with aluminum sulfate become darker red purple in color with development.

Description

Botanical designation: Hydrangea macrophylla.

Cultivar denomination: ‘SAXBICODAPI’.

BACKGROUND OF THE INVENTION

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

The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in Dresden, Germany. The objective of the breeding program was to develop new container-type Hydrangea plants with strong stems, early flowering response and attractive leaf, stem and flower coloration.

The new Hydrangea plant originated from a cross-pollination in 2009 of two unidentified proprietary selections of Hydrangea macrophylla, not patented. The new Hydrangea plant was discovered and selected by the Inventor in 2011 as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Dresden, Germany.

Asexual reproduction of the new cultivar by softwood cuttings in Dresden, Germany since June, 2011 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

Plants of the new Hydrangea have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Saxbicodapi’. These characteristics in combination distinguish ‘Saxbicodapi’ as a new and distinct Hydrangea plant:

- 1. Upright and mounded plant habit.
- 2. Moderately vigorous to vigorous growth habit.
- 3. Strong stems.
- 4. Large mophead-type inflorescences with red purple and green-colored sterile flowers and when treated with aluminum sulfate become darker red purple in color with development.

Plants of the new Hydrangea differ primarily from plants of the parent selections in plant habit as plants of the new Hydrangea are more compact than plants of the parent selections.

Plants of the new Hydrangea can be compared to plants of Hydrangea macrophylla ‘Horwack’, disclosed in U.S. Plant Pat. No. 25,577. Plants of the new Hydrangea differ primarily from plants of ‘Horwack’ in the following characteristics:

- 1. Plants of the new Hydrangea have stronger stems than plants of ‘Horwack’.
- 2. Plants of the new Hydrangea have larger leaves than plants of ‘Horwack’.
- 3. Plants of the new Hydrangea and ‘Horwack’ differ in sterile flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the unique appearance of the new Hydrangea plant 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 plant.

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

The photograph on the second sheet is a close-up view of a typical developing inflorescence of Saxbicodapi'.

The photograph on the third sheet is a close-up view of a typical developed inflorescence of Saxbicodapi'.

Plants used in the photographs were treated with aluminum sulfate.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and in the following description were grown in 3-liter containers in a glass-covered greenhouse in Dresden, Germany and under cultural conditions typical of commercial Hydrangea production conditions. Plants of the new Hydrangea were two years old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 18° C. to 25° C. and night temperatures ranged from 16° C. to 17° C. Some of the plants were treated with aluminum sulfate to “blue” the inflorescences (hereinafter referred to as “blued” plants) and some of the plants were not treated with aluminum sulfate (hereinafter referred to as non-“blued” plants). In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
