Madness® Summer Petunia

Madness® Summer is a named grandiflora petunia selection in the PanAmerican series. PanAmerican Seed lists code PAS3225, a mounded and upright habit, 10–15 inch height, 10–12 inch spread, and flowering from spring through late summer in sun. ## Garden Use Use it as a compact seasonal accent in sunny containers or grouped in a bed. The 8–10 inch spacing on the product page gives a practical starting point for a connected planting while preserving room for the listed spread. “Summer” is the selection name; the stated flowering season begins in spring. ## Growing Conditions Provide abundant light and well-drained soil or potting mix. University of Minnesota Extension recommends five or six hours of sun or more for petunias. Containers dry faster than in-ground soil, so check them regularly and adjust watering to weather and pot size. ## Maintenance Transplant outdoors after frost danger has passed. Water when the root zone begins to dry and follow fertilizer instructions for the selected growing medium. Remove faded flowers when practical to keep the seasonal display neat.
