Description
White Hybrid Shock Wave Petunia Seeds 5967.
Earliest Spreading Petunia with Masses of Rain-Resistant Pure White Blooms.
White Hybrid Shock Wave Petunia (Petunia x hybrida) is the earliest-flowering spreading petunia variety on the market, bringing fast, luminous white colour to containers, hanging baskets, and garden borders. Growing 20 to 25 cm in height with an impressive mounded spread of 60 to 90 cm, a single plant rapidly fills a 25 cm container to overflowing with masses of crisp, 4 cm pure white blossoms. These lush, self-cleaning plants bounce back from heavy summer rain faster than any other petunia, maintaining a tidy, bloom-covered appearance all season long without requiring manual deadheading.

What you need to know to Plant & Grow
Shock Wave Petunias require warm indoor germinating temperatures and surface lighting before transplanting into sunny outdoor locations in late spring.
-
Indoor Sowing (Recommended): Start pelleted seeds indoors in a sterile soil-less mix 6 to 8 weeks before planting out in late spring. Surface sow seeds directly on top of the medium—do not cover, as light is necessary for germination.
-
Pellet Dissolution & Germination: Gently mist sown seeds with water until the protective coating dissolves completely—dissolving the pellet is essential for germination to occur. Apply bottom heat to maintain a soil temperature of 25°C throughout the 14-day germination period (cooler temperatures will extend germination time).
-
Growing On & Transplanting: Once germinated, move seedlings under lights at a cooler temperature of 15°C. Harden off young plants before transplanting outside in late May once spring frost risks have passed, spacing plants 20 cm apart in full sun.
-
Care & Maintenance: Self-cleaning blooms require no manual deadheading. Water consistently and feed regularly with a balanced liquid fertilizer to support rapid growth and continuous white flower production through autumn.
