Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) 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.

(2) The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘H220914’.

(3) The photograph on the second sheet (FIG. 2) is a close-up view of typical inflorescences of ‘H220914’.

(4) The photograph on the third sheet (FIG. 3) is a side perspective view on the left of a typical flowering plant of ‘H220914’ that has not been “blued”, that is, treated with aluminum sulfate, and a side perspective view on the right of a typical flowering plant of ‘H220914’ that has been “blued”.

DETAILED BOTANICAL DESCRIPTION

(5) Plants used in the aforementioned photographs and in the following description were grown during the spring and early summer in 13-cm containers in a glass-covered greenhouse in Lengerich, Germany and under cultural practices typical of commercial Hydrangea production. During the production of the plants, day and night temperatures averaged 17° C. Plants of the new Hydrangea were one year old when the photographs and description were taken. Plants of the new Hydrangea can be successfully treated with aluminum sulfate to “blue” the inflorescences.
