The above and below images are of the F2 Yukako sport. As I try to get the lighting just right to reflect the true color of the green stripes on the write petal background you can seethe variation on different intensities in the green stripe.
As this is the F2, it has remained true to form in both plant leaf and shape and flower color. The F3 is already out of tissue culture culture and in a month or so should have it’s first flowering. If it (as I hope and expect) will demonstrate the same stability, the cultivar will be given a name and it will be registered with AVSA.
