Hardy from zones 7-11, they thrive in full sun and naturally resist Tobacco Mosaic Virus, offering reliable performance without fussing.

Highlights
The Frost Series earns its name through stunning bicolored blooms with an even white "picotee" lining that contrasts beautifully against a signature color base. These 3-4 inch wide flowers sit atop tidy 12-15 inch mounds, making them equally at home in window boxes, hanging baskets, or garden beds. The compact, upright growth habit and virus resistance mean you get reliable, vigorous plants that flower prolifically without the usual petunia babying.
Common Uses
Frost Series Petunias excel in container gardening, particularly window boxes and hanging baskets where their compact mounding habit and abundant flowering shine. They're equally effective planted directly in garden beds and borders, where their upright growth keeps them from sprawling messily. The striking bicolored blooms make them natural focal points in mixed annual plantings or as a cohesive color statement on their own.

Care Instructions
Start Indoors
Start seeds indoors 6-8 weeks before your last spring frost. Petunia seeds are tiny and need light to germinate; sprinkle them on moist seed-starting mix without covering them. Maintain soil temperature around 70-75°F and keep seedlings under bright lights. Transplant seedlings into individual pots once they develop true leaves.
Transplant Outdoors
Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days. Transplant outdoors after all frost danger has passed and soil has warmed to at least 60°F. Space plants 14 inches apart in rows spaced 26 inches apart, or adjust spacing based on your garden layout. Plant at the same depth they were growing in their containers.
Pruning
Pinch back the growing tips of young transplants once they've established 3-4 sets of true leaves to encourage bushier, more compact mounding. Deadhead spent flowers regularly throughout the season to redirect energy into continuous blooming rather than seed production. The upright growth habit typically requires minimal pruning, though you can trim back any straggly stems in mid-summer to rejuvenate plant shape.
