Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying photograph illustrates the overall appearance of the new Poinsettia 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 Poinsettia plant. The photograph is a side perspective views of a typical flowering plant of Dopoinjadwhipe grown in a container.

DETAILED BOTANICAL DESCRIPTION

(2) The aforementioned photograph and following observations and measurements describe plants grown in Rheinberg, Germany during the summer and autumn in 13-cm containers in a glass-covered greenhouse and under cultural practices typical of commercial Poinsettia production. During the production of the plants, day and night temperatures averaged 18 C. and light levels averaged 4,500 lux. Single plants were grown in 13-cm containers and were pinched one time about three weeks after planting the rooted young plants. Plants were 23 weeks old when the photograph and the detailed description were taken. In the following description, color references are made to Pantone Color Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
