Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photographs illustrate the overall appearance of the new Senecio 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 Senecio plant.

(2) The photograph at the top of the photographic sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘Sene Isiyore’ grown in a container.

(3) The photograph at the bottom of the photographic sheet (FIG. 2) is a close-up view of typical inflorescences of ‘Sene Isiyore’.

DETAILED BOTANICAL DESCRIPTION

(4) The aforementioned photographs, following observations and measurements describe plants grown during the spring in 24-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Senecio production. During the production of the plants, day temperatures averaged 10° C. and night temperatures averaged 5° C. Measurements and numerical values represent averages for typical flowering plants. Plants were six months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
