Upright Grandiflora Double Petunia Seeds

Double petunia flowers offer twice the color and visual impact in one bloom! These stunning varieties feature multiple rows of petals on each blossom, producing flowers with a fuller, ruffled appearance. As with other petunias, double petunias offer hues ranging from pale pastels to striking multicolors and deep, rich shades. Plus, seed mixes are available to grow a variety of colors — ideal for creating eye-catching beds, baskets and containers.

These annual beauties prefer well-drained locations with at least 6 hours of full sun daily to thrive and stay looking their best.
