Petunia plant named ‘Sunsurf Akatora’

#Botanical designation: Petunia×hybrida.

#Cultivar denomination: ‘SUNSURF AKATORA’.

#The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Sunsurf Akatora’.

#The accompanying colored photographs illustrate the overall appearance of the new Petunia 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 of the new Petunia plant.

#The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunsurf Akatora’ grown in a container.

#The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunsurf Akatora’.

#The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring and early summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Petunia production. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants were four months old when the photographs and description were taken. 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.
