Comments

Fl. large, soft yellow; perianth segments overlapping; corona slightly darker in tone than the perianth.

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: “Sulphur Prince, a rather late flowering large tall soft yellow trumpet, of beautiful form and quality, was highly commended at the Wisely Trials’ it has the virtues of quite exceptional vigor, freedom of bloom and increase.”
