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.”
