Comments

A description according to the 1964 Guy L. Wilson catalog: “This is a flower of exquisite quality and refinement and quite distinct character as its perianth is built of smoothly overlapping rather long pointed segments, while the crown its rather narrow and goblet-shaped but absolutely smooth. The whole flower is of the purest white possible throughout its entire life.”
