The clematis vine on our porch is a mass of purple blossoms . . .
Except for this single lovely aberration -- a white flower with pale lavender streaks.
Botanists call this sort of thing a 'sport' -- and sometimes new varieties are propagated from sports. And then, these new varieties may begin to revert to the original. So I'm wondering, was my purple clematis (Jackmani, I think) derived from a lighter shade of pale and is it trying to revert? Or is this pretty thing a real sport?
