Do all Black-Eyed Lucy's have some yellow spotting?

[Oxylepy]

How do you produce all-white Black-Eyed Lucy's then?

Luck of the draw and/or great genetics.

Sulfurs tend to make more defined patches, while Fires tend to have the best chance of getting pure whites. I suppose if people took a few pure whites and kept breeding them, ultimately they could make a pure white genetic line, but the number of generations you would go through would be staggering.

this one looks pure:

Have to see it in person to be sure, though
