Pelargonium plant named ‘Kuegraroli’

#Botanical designation: Pelargonium crispum×Pelargonium grandiflorum.

#Cultivar denomination: ‘KUEGRAROLI’.

#The present invention relates to a new and distinct cultivar of Pelargonium plant, botanically known as Pelargonium crispum×Pelargonium grandiflorum and hereinafter referred to by the name ‘Kuegraroli’.

#The accompanying colored photograph illustrates the overall appearance of the new Pelargonium 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 Pelargonium plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Kuegraroli’ grown in a container.

#The aforementioned photograph and following observations, measurements and values describe plants grown 12-cm containers in Dresden, Germany in a glass-covered greenhouse during the summer and under conditions which closely approximate commercial Pelargonium production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were 13 weeks old when the photograph and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
