Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The photographs of the new plant demonstrate the overall appearance of trial garden at a wholesale perennial nursery in Zeeland, Mich., USA. The colors are as accurate as reasonably possible with color reproductions. Some slight variation of color may occur as a result of lighting quality, intensity, wavelength, and direction or reflection.

DETAILED BOTANICAL DESCRIPTION
