Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photographs illustrate typical plants of ‘COUHAGIE’ grown outdoors in Vosges, France. Plants are approximately 2-3 years old, grown in the ground in a trial field. The Figures illustrate inflorescences of the new variety at different stages of maturity. 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.

(2) FIG. 1 illustrates a plant of ‘COUHAGIE’ with inflorescences just fully open, in bright light.

(3) FIG. 2 illustrates a plant of ‘COUHAGIE’ with inflorescences in the fully mature stage of maturity.
