Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

[0022] The accompanying colored photograph illustrates the overall appearance of the new Zonal Geranium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Zonal Geranium plant.

[0023] The photograph comprises a side perspective view of a typical flowering plant of Pacswiros grown in a container.

DETAILED BOTANICAL DESCRIPTION

[0024] The aforementioned photograph and following observations, measurements and values describe plants grown in 19-cm containers during the winter, spring and summer in a glass-covered greenhouse in Dresden, Germany and under cultural practices typical of commercial Zonal Geranium production. During the production of the plants, day temperatures averaged 18 C., night temperatures averaged 16 C. and light levels ranged from 15 kilolux to 100 kilolux. Plants were three months old when the photograph was taken and nine months old when the detailed description was taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
