‘Dainty’ is a name that has been applied to three different varieties. I would guess that this should be Dainty (California), which is a sport from ‘Tricolor’ that should be white with red stripes and a fringed edge. How that differs from ‘Cinderella’, a sport of ‘Fred Sander’ with the same characteristics and which also derives from ‘Tricolor’ via ‘Lady de Saumerez’, I don’t know.
