If you’re fact-checking “Peace lily: thanks to this one ingredient, it will bloom for up to 10 years in a row,” the claim is misleading.
There isn’t a single ingredient proven to make a peace lily bloom continuously for 10 years. Peace lilies (Spathiphyllum) can produce flowers year after year with proper care, but light is one of the most important factors for flowering. They prefer bright, indirect light.

What actually helps
🌱 Bright, indirect light: Too little light may keep the plant alive while preventing flowering.

🪴 Light feeding: A diluted, balanced houseplant fertilizer during active growth can help. University extension guidance recommends using fertilizer at low strength because overfertilizing can burn the roots and leaf tips.

There are commercial flowering treatments involving the plant hormone gibberellic acid (GA₃) that can induce flowering in peace lilies, but that’s a specialized horticultural treatment—not a household “secret ingredient,” and it doesn’t guarantee 10 years of continuous blooming.

Bottom line: If a post says one kitchen ingredient—such as banana peel, rice water, coffee, sugar, or cinnamon—will keep a peace lily blooming for 10 years, that’s not supported by good horticultural evidence. Consistent light, watering, and modest fertilization are far more important.
