The Historic Iris Preservation Society website gallery lists:
From Marble Iris Gardens catalog for 1952: “A rich black-violet with a claret undertone. The uniformity of coloring, coupled with a harmonious dark brown beard, makes this one of the most sensational of all new dark Iris. The flowers are large and full petaled and with heavy substance and a smooth finish.”
From Fleur de Lis Gardens catalog for 1960: “Sensational and very fine black. Extra large and nicely ruffled with reddish undertone predominately in the stands and velvety black falls.”
No yellow, blue or beards other than noted.
