Spathiphyllum 'Sensation'Very large ribbed leaves set Spathiphyllum 'Sensation' apart as a giant peace lily. Glossy green blades rise on long petioles from a broad basal clump, with tall white spathes appearing above the foliage in steady conditions. As the rootball and leaf mass increase, pot stability and deeper moisture checks matter, while broad leaves can collect dust across the ribbed surface.
