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.

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

DETAILED BOTANICAL DESCRIPTION

(3) Plants used in the aforementioned photograph and in the following detailed description were grown during the autumn and winter in 13-cm containers in a glass-covered greenhouse in Rheinberg, Germany under natural season conditions and 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. Plants were pinched one time about three weeks after planting rooted cuttings and were 23 weeks old when the photographs and the description were taken. Measurements and numerical values represent averages for typical flowering plants. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
