Corona very widely expanded, with rim deeply dentate.
A description according to deJager’s 1965 catalog: “a very large and immensely tall flower of distinct character with large spreading white perianth; the large wide and medium length crown is also white and has a very boardy flanged deeply serrated brim, which give the flower a most distinct and striking appearance.”
There are no photos of "Kibo" in Daffseek.
