Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The photographs of the new plant demonstrate the overall appearance and unique traits of Purple Illusion as a three-year-old plant grown in a full-sun trial garden in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color.

(2) FIG. 1 shows the habit of the new plant in full flower.

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

DETAILED BOTANICAL DESCRIPTION

(4) The following descriptions and color references of Veronica Purple Illusion are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used.
