Corona bright clear yellow. 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: “For those who like a well contrasted bicolor, ‘Jack Spratt’ is a very bright and effective; it is a neat flower with pure white perianth, and slender bright yellow trumpet and is a very good doer.”
There are no photos of "Jack Spratt" in Daffseek.
