Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying photograph illustrates the overall appearance of the new Dahlia 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 Dahlia plant.

(2) The photograph is a side perspective view of a typical flowering plant of Dodaxrasic grown in a container.

DETAILED BOTANICAL DESCRIPTION

(3) The aforementioned photograph and the following observations and measurements describe plants grown during the summer in 17-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under environmental conditions and cultural practices which approximate those generally used in commercial potted Dahlia production. During the production of the plants, day temperatures ranged from 18 C. to 30 C., night temperatures ranged from 16 C. to 22 C. and light levels were at least 135 watt/m.sup.2. Plants were pinched one time about four weeks after sticking unrooted cuttings. Plants were twelve weeks old when the photograph was taken and eleven 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.
