Madness® Spring Petunia

Madness® Spring is a named grandiflora petunia selection in the PanAmerican Madness series. The official detail page identifies its code as PAS3220 and lists mounded, upright growth, a 10–15 inch height, 10–12 inch spread, and flowering from spring through late summer in sun. ## Garden Use The moderate, upright mound suits containers and defined groups in sunny seasonal beds. Use the listed 8–10 inch spacing as a planting guide and leave room for the recorded spread. “Spring” is part of this selection’s name; the page separately describes its bloom window as extending through late summer. ## Growing Conditions Provide plenty of light and soil or potting mix that drains well. University of Minnesota Extension recommends at least five or six hours of sun for petunias. Check containers more frequently than in-ground plantings because their smaller soil volume dries sooner. ## Maintenance Set plants out after frost danger has passed. Water as the mix begins to dry and follow the fertilizer label for container or bed plantings. Remove faded flowers when practical to maintain a tidy display.
