Tidal Wave Silver
A silver-edged spectacle that catches the light like moonlit lace—Tidal Wave Silver spills in a trailing cascade of soft, luminous blooms with cool-toned, subtly veined petals. Expect a velvety, petal-rich texture and a dense, spreading habit that blankets containers and beds with long-lasting color from early summer through fall. Grow it for show-stopping mass color in hanging baskets, window boxes, and tumbling borders where its trailing presence becomes the centerpiece.

Sowing Tips
Transplant Conditions
Wait until soil reaches 55°F and nights stay above 50°F before moving outdoors. Harden off for 7 days first.
Expert Note
Start petunia indoors early (they’re slow to establish), keep seedlings bright to prevent legginess, then transplant after night temperatures are reliably warm.
