Peace Lily (Spathiphyllum spp.)
The Peace Lily (Spathiphyllum spp.) is a beloved tropical shade-loving perennial prized for its lush, deep emerald ribbed foliage and pure white architectural blooms. Highly communicative, the Peace Lily gently droops its leaves when thirsty, serving as one of the clearest visual communicators in the plant world.
What is commonly called the Peace Lily "flower" is actually a modified white protective leaf bract known as a spathe. The true flowers are the tiny, dense florets clustered along the central vertical spike, known as the spadix.

Peace Lily is NOT a "True Lily"
True lilies (genera Lilium and Hemerocallis, like Easter or Tiger lilies) contain a severe, unidentified toxin that causes acute, fatal renal failure in cats from even minor pollen ingestion. In contrast, Peace Lily (Spathiphyllum) is not a true lily. It contains insoluble calcium oxalate crystals which cause mouth irritation, drooling, and vomiting, but does NOT cause feline kidney failure.
Why Won't My Peace Lily Bloom?
While Peace Lilies survive in dark corners, they require bright, filtered indirect light to generate the metabolic energy needed for white spathes. If foliage is lush but no blooms appear, move the plant 3 feet closer to an east-facing window and apply a diluted balanced organic fertilizer during spring.
