#In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown in Odense, Denmark during the spring in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial Osteospermum production. During the production of the plants, day temperatures ranged from 14° C. to 20° C., night temperatures averaged 14° C. and light levels ranged from 200 to 800 watts per square meter. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were about 15 weeks old when the photographs and description were taken.
