(R. Ernst, 96) Mid season bloom. 37"

"Sweet apricot-orange coloring. Standards have a slight pink cast more visible at the midribs that deepens the orange color. Bright orange beards on apricot-orange falls. A very pale shoulder wash of violet deepens the color. Mild ruffles and lace. Seven to nine buds. American Iris Society Honorable Mention '98."
