The tallest of the Ride The Wave family, award-winning Tidal Wave petunias create an extremely full plant covered with an amazing number of 2-in. (5-cm) blooms. Plants first grow outward, then up, and finally in both directions to make an outstanding, shrublike shape that continues to hold its form all season. An excellent landscape performer with terrific Botrytis tolerance and quick recovery from rain, the plants resist lodging so they won’t fall open and expose a bare centre like other petunias can. Tidal Wave is well-suited to large containers, or sold green in 1801 or similar pack size. Plant habit is based on how closely the plants are placed in the garden. Spaced a minimum of 12 in. (30 cm) apart, Tidal Wave forms a dense, mounded hedge, 16 to 22 in. (40 to 55 cm) tall. The stiff stems help to maintain the habit through the season. Spaced up to 24 in. (60 cm) apart in the garden, Tidal Wave spreads like a groundcover, 2.5 to 4 ft. (75 to 120 cm) per plant. Tidal Wave is only supplied as pelleted seed.
