Gardeners' Notes:

This beauty was received as a gift, and what a gift, indeed! it's velvety depth of color is stunning, and this year, despite the draught here in western KY, it is blooming for the second time, now in late October. Mme. Gaudichau must have been a stately and elegant beauty to be remembered in this iris' name.

Last year I purchased a fat, plump rhizome from Superstition Iris Gardens (love them) and early this Spring it sent up 2 strong, straight stalks each loaded with 4 dark purple blooms. Beautiful flowers.
Hydridized by Millet & Fils, introduced in 1914, AIS Award of Merit in 1924, 1927 and 1929. Royal Hort. Society Awards in 1924, 1927 and 1929.

Per the 1928 Lee R. Bonnewitz Peony and Iris catalog from Van Wert, Ohio:
MADAME GAUDICHAU (Millet). The President of the Iris Society, Mr. Wister, discovered this variety in France during the war, and at his suggestion we immediately imported it, and it is now universally acknowledged to be one of the best Irises in the world. We have, we believe, the largest stock of it in the United States, but we are offering to sell this year, only one thousand rhizomes, as we wish, if possible, to plant a full acre of it to supply the immense wholesale trade with the Catalog Seed Houses and Nurseries which we are sure will develop for this and the other outstanding varieties of Irises. $1.00
