DETAILED BOTANICAL DESCRIPTION

(4) Plants used in the aforementioned photographs and in the following detailed description were grown during the summer to late autumn in 16.5-cm containers in a polyethylene-covered greenhouse in Encinitas, California under natural season conditions and cultural practices typical of commercial Poinsettia production. During the production of the plants, day temperatures averaged 21 C., night temperatures ranged from 13 to 14 C. and light levels ranged from 3,500 to 4,500 foot-candles. Plants were pinched one time about six weeks after sticking unrooted cuttings and plants were 22 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.
