Green shading at base of flower; cup has expanded mouth.
A description according to 1947 Max Schling Seedsmen catalog: “An exquisite pure ice white trumpet of utmost refinement, perfection of proportion, beauty of form and quality of texture. Broad perianth of fine substance and lovely somewhat slender but graceful bell-flanged trumpet, green rather than yellow shading at the base of the flower.”
There are no photos of "Saint Mary" in Daffseek.
