#Plants shown in the aforementioned photographs and used in the following description were grown in containers under conditions which closely approximate commercial production conditions during the summer in an outdoor nursery in Hillegom, The Netherlands. Plants in the photographs and those used for the description were about one year old when the photographs and desciption were taken. During the production of the plants, day temperatures ranged from 14° C. to 30° C. and night temperatures ranged from 6° C. to 17° 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.
