Sea campion is a tough, mat-forming coastal perennial known for its masses of white flowers with inflated calyces, perfect for rock gardens or seaside plantings. It tolerates salt spray, poor soils, and exposed positions, making it ideal for challenging spots where other plants struggle. Plant in full sun to partial shade with excellent drainage and water only when the soil becomes dry.
