Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying colored photograph illustrates the overall appearance of the new Solenostemon 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 Solenostemon.

Root description.—Medium in thickness, fibrous; typically white to creamy white in color, actual color of the roots is dependent on substrate composition, water quality, fertilizers, substrate temperature and age of roots.
