Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The photograph of x Mangave ‘Dragon Lady’ demonstrates the overall appearance of the new plant including the unique traits as a two-year-old plant grown in a greenhouse and moved to a full-sun trial garden in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, temperature, source and direction may cause the appearance of minor variation in color.

(2) FIG. 1 shows a plant from above.

(3) FIG. 2 shows a close-up of the variegation coloration and marginal teeth.
