Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0012] The accompanying photograph in FIG. 1 illustrates in full color a typical plants of RIKACPMC grown outdoors in Grand Haven, Mich. Plants in FIG. 1 are approximately 5 years old, and exhibit the characteristic semi-pyramidal growth.

[0013] FIG. 2 illustrates a plant of the new variety at approximately 2 years old in a 2 gallon container. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
