Fl. ivory white, facing slightly downwards; perianth segments very broadly ovate, not prominently mucronate, a little inflexed, with margins slightly wavy, very smooth, overlapping half; the inner segments twisted; corona cylindrical, angled, rim flanged, notched, minutely crenate.

According to The American Horticultural Society’s 1937 issue of the The American Daffodil Year Book, Guy L. Wilson’s article “Some Modern Daffodils for Garden Decoration” states: “It is a perfectly beautiful large flower of ideal form and balance, great substance and very durable, growing in size and whiteness as the flower ages, a plant of splendid vigor and freedom of bloom, making heavy healthy bulbs.”
