#The new Ruscus has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.
#The aforementioned photographs, following observations and measurements describe plants grown in 2-liter containers in Boskoop, The Netherlands, in an outdoor nursery and under commercial production practices. Plants used for the photographs and the description were about two years old. The photographs and description were taken during the fall with day temperatures ranging from 7° to 15° C. and night temperatures ranging from −4° C. to 8° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
