A description according to the 1947 Max Schling Seedsmen catalog: “Exceptional flower of beautiful proportion and finish, with a large recurved deep trumpet supported by an exceptionally substantial perianth; good stem and up-looking flower; the perianth is pale primrose and the trumpet a pure moon yellow when opening, giving the effect of moonlight through mist. When fully open the perianth turns slightly paler, justifying its classification under the is class.”
