Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying photograph illustrates the overall appearance of the new Osteospermum 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 Osteospermum plant. The photograph is a side perspective view of a typical flowering plant of Doostmardarli grown in a container.

DETAILED BOTANICAL DESCRIPTION

(2) The aforementioned photograph, following observations and measurements describe plants grown during the summer and autumn in 10.5-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under cultural practices typical of commercial Osteospermum production. During the production of the plants, day temperatures ranged from 18 C. to 30 C. and night temperatures ranged from 14 C. to 18 C. Plants were pinched five weeks after sticking unrooted cuttings; plants were 13 weeks old when the photograph was taken and 15 weeks old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
