Tidal Wave Series petunias are vigorous hybrid annuals that deliver one of the largest, most award-winning trailing displays of the season. These adaptable plants grow 4-8 inches tall and mature in 100-109 days, thriving in full sun across hardiness zones 7-11. What makes them truly special is their remarkable growth flexibility: depending on your spacing, they'll vine, mound, or spread as a ground cover, giving you control over how they perform in your garden. Their hardy, prolific blooms make them as reliable as they are spectacular.

Tidal Wave Series petunias possess a genuinely unique growth habit that shifts based on how you space them, giving you remarkable garden design flexibility. At 36-inch spacing, they'll sprawl dramatically as ground covers or trailing specimens, while tighter spacing encourages a more mounded form. The vigorous vines burst continuously with blooms throughout the growing season, earning them recognition as one of the most award-winning petunia lines available. This combination of adaptability, vigor, and prolific flowering makes them standout performers for gardeners seeking reliable, large-scale color impact.
Tidal Wave Series petunias are grown exclusively for ornamental display. Their trailing and ground-cover capabilities make them exceptional choices for hanging baskets, window boxes, and sprawling bed plantings where you want dramatic seasonal color impact. The mounding habit also allows them to fill large landscape areas efficiently, while their trailing form excels in elevated containers where cascading blooms are desired.

Start seeds indoors 6-8 weeks before your last spring frost. Sow seeds on the surface or barely press them into moist seed-starting mix, as petunia seeds need light to germinate. Maintain soil temperature around 70-75°F and provide bright, indirect light until seedlings emerge. Keep soil consistently moist but not soggy to prevent damping off.
Transplant seedlings outdoors after all danger of frost has passed and soil has warmed. Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days. Space plants 36 inches apart to fully accommodate their vigorous, spreading growth habit. Plant at the same depth they were growing in containers to avoid burying the stem.
Pinch back young seedlings once they have 4-6 leaves to encourage branching and fuller growth. During the growing season, deadhead spent flowers regularly to maintain vigor and promote continuous blooming. Light pruning to shape or control the spreading habit is optional and depends on your desired form; the plants naturally adjust between mounding and trailing depending on spacing and light conditions.

“Tidal Wave Series petunias are modern hybrid developments from Petunia x hybrida breeding lines, created to deliver exceptional vigor and novel growth characteristics. The series was specifically bred to exhibit variable growth habits, a breakthrough that allows the same plant to perform differently depending on cultural conditions. This flexibility represented a significant departure from traditional petunia breeding, which often locked plants into fixed growth forms. The award-winning status of the series reflects years of refinement to achieve the vigorous, heat-tolerant performance that made them popular among both home gardeners and professional landscapers.”
