Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The photographs of the new plant demonstrate the unique traits of ‘Pink Chenille’ and the overall appearance of a three-year-old plant in a full-sun, outdoor, research facility of a wholesale perennial nursery in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Variations in the ambient light spectrum, source, and direction may cause the appearance of minor variations in color.

(2) FIG. 1 shows the new plant in flower in the research facility.

(3) FIG. 2 shows a close-up of the flowers.
