Cool-season color for fall and winter windowboxes, these petite violas pair creamy yellow petals with deep purple faces—a cheerful two-tone that reads bright even on gray days. They're smaller than pansies but tougher in the cold, and they'll keep flowering through Alabama's mild winters if you deadhead spent blooms.

Plant them now through December in any decent soil and a spot that gets decent light. They handle frost without complaint and ask very little once established.
