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 of 2) is a side perspective view of a typical flowering plant of HIFIR grown in a container.

(3) The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical inflorescence of HIFIR.

DETAILED BOTANICAL DESCRIPTION

(4) Plants used in the aforementioned photographs and in the following description were grown during the autumn in 13-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under cultural practices typical of commercial Hydrangea production. During the production of the plants, day temperatures ranged from 20 C. to 35 C., night temperatures ranged from 10 C. to 22 C. and lightly levels were about 4,000 lux. Plants of the new Hydrangea were pinched one time and were two years old when the photographs and description were taken.
