Yuki translates to snow in Japanese, and this variety creates a soft
blanket of brilliant, large, pearly white snow flowers sitting atop
unique variegated foliage. The 1939 seed catalog for J. Tanaka &
Co. from Osaka, Japan, mentions that the Japanese love to grow
morning glories on rooftop gardens in cities or large towns, and
mentions that these are very well suited to rooftop containers.
