Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0027] The accompanying colored photographs illustrate the overall appearance of the new Catharanthus 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 Catharanthus plant.

[0028] The photograph at the top of the sheet is a side perspective view of a typical flowering plant of ‘Suncatfe 43’ grown in a container.

[0029] The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Suncatfe 43’.

DETAILED BOTANICAL DESCRIPTION

[0030] The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer/early autumn in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial production. During the production of the plants, day temperatures averaged 25° C. and night temperatures averaged 15° C. Plants were six months old when the photographs were taken and seven months old when the description was taken.
