Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photographs illustrate 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 photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors ofthe new Poinsettia plant.

(2) The photograph on the first sheet comprises a side perspective view of a typical flowering plant of LAZZPOSUGI grown in a container.

(3) The photograph on the second sheet is a close-up view of a typical inflorescence of LAZZPOSUGI.

DETAILED BOTANICAL DESCRIPTION

(4) The aforementioned photographs and following observations and measurements describe plants grown during the autumn and winter in 13-cm containers in a glass-covered greenhouse in Merano, Italy and under cultural practices typical of commercial Poinsettia production. During the production of the plants, day temperatures ranged from 15 C. to 20 C., night temperatures ranged from 10 C. to 15 C. and light levels ranged from 40 to 55 klux. Plants were pinched one time two weeks after planting, grown under natural daylength conditions and were five months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
