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: “The special value of ‘Kenbane’, a flower of my own raising, lies in its lateness. It comes when nearly all other trumpets are over. It is a very large bold flower of great substance, holding its head well up on a very strong stout stem, and having dark blue-green upright foliage: it is a very vigorous plant, making a fine display when others are past their best.”
