The Earliest Spreading Petunia with Masses of Rain-Resistant Coral-Pink Blooms.
Coral Crush Hybrid Shock Wave Petunia (Petunia x hybrida) is the earliest-flowering spreading petunia variety available, delivering fast, high-impact colour to hanging baskets and garden beds. Growing 20 to 25 cm in height with an impressive mounded spread of 60 to 90 cm, a single plant quickly fills a 25 cm container to overflowing with masses of vibrant, 4 cm coral-pink blossoms.

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 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 coral-pink flower production through autumn.
