From J.C. Nicholls iris catalog for 1928: “Snow white with beard and throat greenish white. Good texture. Falls nearly horizontal. Grows and blooms well. Fine Iris of a very pure color. Would be wonderful if a little larger, taller, and the blooms were carried on the stems less stiffly.”
Note: Thought to be an albino sport of Flavescens.
