Snow on the Mountain – Promoting Variegation
I have used Snow on the Mountain to crowd out other invasive weeds, but this year, more than half of my Snow on the Mountain has reverted to solid green. The bed is in full sun for more than 10 hours a day but the soil quality is poor. What can I do to promote the white-green variegation?

There is nothing that can be done. Variegation is a genetic mishap that only shows in clusters of cells at the originating growth point. Anything that does not grow from this original cluster will not have variegation.
Unfortunately, there is no way to control this, and it may turn up again randomly in the future.
