Madness® Sky Blue Petunia

Madness® Sky Blue is a named grandiflora petunia selection with blue-toned flowers. PanAmerican Seed identifies the exact selection as PAS1527149 and lists a mounded, upright habit, 10–15 inch height, 10–12 inch spread, and spring-through-late-summer bloom in sun. ## Garden Use Use the blue color as a cool accent in a sunny annual bed, container, or coordinated group planting. The listed 8–10 inch spacing helps create a connected display while allowing room for the mature spread. Pair it with contrasting warm colors or foliage without mixing labels when separate selections need to remain identifiable. ## Growing Conditions Petunias flower best with abundant light and well-drained soil. University of Minnesota Extension recommends at least five or six hours of sun. A container’s limited soil volume dries faster than a garden bed, so check moisture more often during warm or breezy conditions. ## Maintenance Wait until frost danger has passed before planting outdoors. Water when the root zone starts to dry and follow fertilizer directions for the planting medium. Remove faded blooms when practical to keep pots and beds tidy.
