I got a very interesting seedling with striped pink/white petals – yuri_panchul_2005_017_nodami_ushiro.
Striped sasanquas are very rare – the only one I know is a hybrid Stars’N'Stripes, and Stars’N'Stripes is not really a typical sasanqua – it is sensitive to sunlight and has elongated leaves comparing to traditional sasanquas. Most bicolor sasanquas are not striped, some are blotched – the blotching pattern is the result of a relatively harmless virus.
My new seedling’s parent is probably Nodami Ushiro. I am going to evaluate it for a while to make sure this striped pattern is stable. In the main time I will probably propagate it by grafting.
