Description

DESCRIPTION OF THE DRAWINGS

(1) The accompanying photographic images illustrate the new variety at approximately six months of age, with the colors being as nearly true as is possible with color illustrations of this type:

(2) FIG. 1 illustrates a close-up view of a flower of the new variety; and

(3) FIG. 2 illustrates a close-up view of two flowers of the new variety.

DESCRIPTION OF THE PLANT

(4) The following detailed description sets forth the characteristics of the new variety. The plants were grown in a greenhouse heated to a minimum of 16 C. and covered with 33% black shade cloth.
