Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0021] The accompanying colored photographs illustrate the overall appearance of the new Calibrachoa 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 slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa plant.

[0022] The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Duealcostra’ grown in a container.

[0023] The photograph on the second sheet is a close-up view of typical flowers of ‘Duealcostra’.

DETAILED BOTANICAL DESCRIPTION

[0024] The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Calibrachoa production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Rooted young plants were pinched one time three weeks after planting and were 16 weeks old when the photograph and description were taken.
