Description

DESCRIPTION OF THE DRAWINGS

(1) The accompanying photographic images illustrate the new variety at approximately twelve 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 an entire plant 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 greenhouse heated to a minimum of approximately 13° C. during the cool season, which is otherwise kept at ambient temperatures with a light shade of about 30% in the hot season. The color readings and measurements were taken indoors in Grand Saline, Tex. under fluorescent lighting near natural window light on approximately twelve month old plants that were grown in 2 gallon containers. Color references are primarily to the 1995 R.H.S. Colour Chart of The Royal Horticultural Society of London, 3.sup.rd Edition, except where general color terms are used.
