Supercascade White Petunia

Supercascade White is a single grandiflora petunia with large white flowers on a compact, upright-mounded plant. PanAmerican Seed lists 4–5-inch blooms and a 10–15-inch height by 10–12-inch width, with flowering from spring through late summer. ### Garden use The white flowers brighten sunny containers and annual beds and pair easily with stronger colors. The plant’s modest, mounded form suits patios, path edges, and grouped seasonal displays. ### Growing conditions Grow in full sun and moist, well-drained soil. Illinois Extension describes petunias as half-hardy annuals, so treat this selection as seasonal color where frost occurs. The exact breeder page documents the white selection’s flower size, plant habit, mature dimensions, and bloom season. ## Maintenance Water to keep the root zone evenly moist, and let excess drain away. Pinch stems if they become stretched or untidy, and clear away damaged growth during routine care. Replace the plant once cold weather ends the seasonal display.
